HVAC Engineer Skills

Figure. The HVAC practical engineer

 

A practical engineer

 

The best part after graduate from the engineering faculty is to be an engineer. Many people though that engineer is someone who can create something usefull by just produce it. The statement is not wrong but it just feels not complete whitout how to market the product, for example an HVAC engineer know how the air conditioning equipment work, how to calculate the cooling load, know the detail to make one simple air conditioning unit. Is it stoped until that step? I keep this question and answer it in the middle or at the last of this paper.

 

A practical engineer combine the theoritical knowlage with the practical training, in some case they can perform engineering duties. They know well the equipments work even more datail.

 

Being a practical engineer will get more advances in knowing the field like how to install the equipment, they know the principal and detail work of many aquipment. But in some cases practical engineer can not make basic design or detail design and also important decision related to the cost estimation. Therefore an engineering job to make such work.

 

Building construction

 

Many buildings constructed in this world, from small building until high risk building. Those building will be filled by many people who stay for a long time periods, the design made by engineer shall configure about the comfortability in the building design. In this step mechanical or HVAC engineer take part on design begins from basic design until the porsion of engineering job is finished.

 

What would be HVAC engineer know about the design in a building? The basic knowledges of air conditioning and that what next. The concept and construction or installation of air conditioning equipments. People in the building need healthy air ventilation so they can work inside the building, people need camfortability so they can work longer inside it.

 

To be an engineer we have to learn about equipments that used for construct an air conditioning system in a building. The equipment such as ducting, fans, water chillers, pumps, energy safing equipment, etc.

 

It is important to study those equipments to be an engineer who work in construction companies. By selecting one equipment from many types in the market is also a skill should have by HVAC designer or engineer. Selection of equipment is one of the steps in air conditioning design. This step also important it is because related to cost management in construction building project.

 

For example, water chiller, if I search using google there so many product of water-chiller sell on internet. Many companies offer good water-chiller equipment and also the installation even the maintenance for a couple of years. Some companies offering the guarantee for more than two years. In this case the engineers have to choose one of the products offered by the company.

 

chiller in the market

 

Simple control, the easiest control is on and off. costumers want to have a simple control for many equipments. Engineers should have skill to make an easy control in HVAC system. Usually in the college a control system is given to the student but it is still the theoritical study. In some real case engineer facing the problems about the sensors (pressure gauges, temperature gauges, etc). Where to put those sensors? Is it after compressor or before comrpessor, and so on. For engineer this is kind a simple problem, so the best way to solve this problems the student should know more the real industries by visiting them.

 

Design a system

I want to have skill and sense of engineering especially on air conditioning design. Designer has to know the basic understanding of design such as; draw the P&ID (piping and instrumentation diagram), basic concept of air conditioning system and also the equipments, cost estimation and scheduling the projects.

 

Piping and instrumentation diagram should be conducted with the skill of using CAD program. Engineer will be close with CAD program in a computer for example, AutoCAD. AutoCAD is a powerfull program for drawing many object. It could be used for 2D or 3D, but P & ID always made in 2D. Drawing skill is not an instant, an engineer should trained them self to make it as their habitual.

 

As I mentioned before that engineer should know about the control system, P & ID is the place to put the instrumentation equipment, i.e. presure gauges. So engineer could apply the basic knowledge of control in P & ID sheet. The pressure gauge may be represented by a symbol. If an engineer can make P & ID logically they can read it and understand the system work on it.

 

Equipments

 

In the futere, I want to understand more detail how all equipments related to air conditioning system works. So I can be come a specialist on HVAC and genaral mechanical engineering, true things I come here is to study and mastering air conditioning system works for a building. But the fact until now I don’t get what I was propose to. And I realized that I have to study what I propose by my self.

I want to study more about design and also the equipment, such as;

1. cooling system in the power plant
2. cooling system in the factories
3. cooling system in a high risk building
4. etc.

 

Cooling system in the power plant

 

Power plant is a huge energy conversion plant, the energy convert from mechanical to electrical by utilize steams to rotate a turbine and electric produce in generator. The steam than cooled by using cooling systems. Most power plant builds at near the beach to get cooling water but for some power plant (geothermal plant) they don’t use water from the beach but using cooling tower. And I think, those system is not one of air conditioning system that learn in the college.

 

Somehow I need more study another type of cooling system beside the regular air cooling system.

 

 

Cooling system in the factories

 

Food industrial has a major need on refrigeration system, because many kind of food has to be refrigerated to maintain the condition of body and the inside such as vitamins.

 

I was in fish processing factory when I was in undergraduate (mechanical engineering dept. University of Indonesia), the factory using a huge refrigeration system to keep the fish freez. The temperature on the food saving container is below -10 ^oC, I was look for the compressors they used and it was a big compressor with ammonia as the refrigerant. Not only the compressor but also the control of all those equipments. I am interest with the system and I want to make design that refrigerant system.

 

Cooling system in the high risk building

 

The focus application in air conditioning system is to maintain and control the air in the building. So many high risk building using central air conditioning system in order to keep the room in comfortable for occupant (people). High risk building usually used for office, appartement, and a mall in the ground floor. All the function for the building will be work if air is comfort for people stay inside it.

 

I want to learn about how the trully system work and also the equipment use in the building. The ducting technology, the chiller technology, fan technology, control relates to air conditioning tecnology, etc. but I don’t feel or I can’t absorb any of those things in the college, but I can see it in Mr. Choi, he can make a design on his company. I want to learn from him.

 

Price, Market and Bussines

 

There must be a cost for each action, to make all the design come true there is a cost for it. Engineers also have to estimate all cost to actualize the plan in design, and it is necessary to take a profit on what they do.

 

Price the design, price the construction or price the products and gain the profit it just same as make the products and gain the profit. But there is another problem that how to market the products. It is obviously that people will be interest with product that has a good quality but if the product is not exposed to market with selling strategy so the product would not be useful.

 

Engineering is also a bussiness to get more profit. The profit is measured by how many money that could be get by engineer. So engineer also has to sell their product/design to the market, use relation to sell the products is likely effective because the relation to other is one asset to know the products very well. Make as many relations to other people so they know your products.

 

Advertisement is another key to enter the market. TV, radio, internet, seminar, expo agenda, etc are the media for advertise the products.

 

Conclussion

 

It is a great deal to be an engineer, by using their intelectual making something to help many people life easier. Engineers have to know many thing related to their specialization; equipment, design (drawing, P&ID, etc), cost estimation, etc. and another important thing is marketize their products to as many costumers.

 

And I want to have all those skills.

 

Working Grand Design

my design

This grand design builds as a short guidance for my working time in this world, as I am who responsible for the family welfare. I hope this grand design will be implemented and make it as an effort to motivate my self.

 

This is the explaination of the grand design;

First after finished the Master Degree in Korea, the next step is working in the same major as my education background that is in Refrigeration and Air Conditioning Engineering, actually there are many things to choose on the working field, such as (look at this list);

1. Researcher

2. R&D (Research and Development in HVAC&R Company)

3. HVAC engineer

4. Refrigeration engineer

5. HVAC facility engineer

..

Even as a sales engineer,

 

I rather choose as HVAC engineer, despite in this major I am directed as a Researcher on Boiling and Convection which mean relates to heat and mass transfer, but I am the master student and I am choosing my capacity as HVAC, why I’m choosing HVAC, it is because after graduate the industry needs in HVAC engineer is very high. And what kind of industry will take part on HVAC, as I know there are;

1. The Oil/Gas/Power

2. Construction

3. Consultant

5. Manufacture

..

Even home industry,

 

Before go to Oil/Gas/Power industry I have to prepare some of the competention of HVAC engineer, such as (look the grand design figure above) basic science of HVAC and the most important is working experiences in this HVAC field. Absolutely the industry will choose their new commer with high quality which mean having working experience related to HVAC. How come I get experience working on the company while I am studying, I am not worry about it, the trully is, my present in this college it is because my name is used as some of projects being done even I am not directly involve on it, I could use it as refference in my ressume as working experiences. What next chalange is the language, if I want to works overseas my English should be improved even now I am using it as my communication language to krorean people, I think I need more practice in English and another language such Korea and Arab. I will learn it as a naturally it because I don’t have any more time to learn it.

Oil/Gas/Power Instead of the money [ being rich is a good things ], this area is so interesting, when I was graduate from Mech.Eng, I want to work related to my Final Report (it was about Power Cyclus) and then Alloh Swt, destined me work in PLN-E, power plant consultant and subsidiary company of PLN, and now writes this grand design it is my necessity to build my future carriers to entering oil company in Indonesia.

In the figure above for the working place I choose Overseas Oil/Gas/Power Company, because these companies are more attractive with the numeration and the working challenge is higher than in Indonesia and the most important is the working experience that I can get, as I said to build my carriers in Oil Company in Indonesia. A good Carrier should be build to have easy steps or smooth way to the top, as manager until director. This carrier shall not oddmented; I have to take some advantages in the carrier such as Working Partner and Big Network. Partner that I can trust on making my dream that is Build a Company and Network to support the company with some projects.

Aah, at last my dream to make a company will be come true, this company should be rise and grow fast to defeat other competitors (even big competitors).

 

I know this grand design will not exactly would come like written as it is. But I know by doing this is one step to the future.

Ngapain sih kuliah lagi

kuliah lagi

Alasan-alasan kenapa banyak orang ingin kuliah lagi, ini bisa terjadi pada Anda pembaca budiman, sama halnya perasaan yang anda alami ketika meninggalkan bangku sekolah tingkat SMU (senior high school). Perasaan tentang hal-hal yang menyenangkan ketika suatu tingkat pendidikan terlewati seperti teman, kegiatan, perasaan tidak terikat waktu, dan lain-lain.
Pada saat anda sudah bekerja, anda akan merasakan keinginan untuk kembali ke kampus minimal untuk melihat-lihat perkembangan kampus dulu dan sekarang dan terkadang ingin kembali kuliah lagi, baiklah cukup perasaan mellownya sampai disini. berikut alasan rasional kenapa orang mau kuliah lagi:
-
pertama, jika anda lulusanD3, atau diploma, anda merasa ada perbedaan status sosial, kepegawaian, karyawan di tempat anda bekerja dan tentu saja gaji anda lebih kecil dan sulit untuk naik dengan cepat dibandingkan dengan rekan kerja anda yang memiliki gelas S1 (Bachelor degree), maka dari itu anda punya alasan kuat untuk melanjutkan kuliah lagi ke tingkat S1.
-
kedua, jika kamu adalah karyawan, pegawai negeri, pegawai BUMN yang sudah lama bekerja sedang gelar anda adalah S1 maka untuk meningkatka nilai tawar anda pada posisi jabatan yang penting maka anda akan berfikir untuk menambah gelar anda baik itu Magister Management, MBa, MSc, dan sebagainya karena biasanya pada jabatan tertentu memiliki kriteria gelar.
-
ketiga, anda sudah merasa bosan dengan pekerjaan anda sehingga anda berhenti dan memutuskan untuk mengambil kuliah dan berniat mencari pekerjaan baru yang lebih baik dari sebelumnya setelah lulus kuliah.

ke empat,, coba anda isi alasan anda mau kuliah lagi di commentlah (klik disini)

cara memperoleh beasiswa luar negeri

buat masa depan

Saya akan mengajak kamu untuk berhenti sejenak untuk berfikir antara kuliah lagi atau langsung kerja. saya menganggap kamu sudah memilih melanjutkan kuliah pada master degree, tanpa banyak panjang kata, saya akan mengajarkan bagaimana memperoleh beasiswa yang persis saya jalani.

modal dasar /persyaratan general:

• • • • • • • IPK minimal 3 dari skala 4
            • TOEFL minimal 500 PBT atau 61 IBT
            • Niat dan Interest pada jurusan
            • Link
            • Dana
            • Percaya-diri

Jika sudah kamu miliki, maka kamu beruntung bisa melanjutkan pendidikan ke tahap master degree.
Alasan kenapa IPK minimal 3 dari skala 4, karena IPK pada saat mendaftar beasiswa ke perguruan tinggi baik luar maupun dalam biasanya mensyaratkan IPK minimal 3 bahkan ada yang lebih dari 3, namun tidak tertutup kemungkinan IPK dibawah 3 bisa diterima biasanya dengan syarat mendapat rekomendasi dari Pembimbing atau Advisor (advisor biasanya adalah Professor)
-
Alasan TOEFL minimal 500 PBT (paper base test) atau 61 (internet base test), TOEFL saat ini dipercaya untuk menunjukkan tingkat penguasaan bahasa inggris dan ini penting karena biasanya menjadi syarat umum untuk di terima di perguruan tinggi luar negeri
-
Niat, innamal ‘amalu binniyatu. ini penting karena kamu harus strugle dengan kehidupan di negara asing, dan kamu juga harus yakin pilihan jurusan anda benar. jangan asal mengambi jurusan karena sedang trend karena dengan mengikuti trend akan banyak saingan bagi kamu
-
Link, diperlukan karena biasanya dengan memperoleh link dari professor atau advisor akan mempermudah jalan kamu untuk memperoleh beasiswa.
-
Dana, kamu diwajibkan punya uang sebagai saving money jikalau beasiswa kamu tidak mencukupi namun biasanya besaran dana beasiswa yang akan kamu peroleh sudah cukup untuk living cost, tapi untuk menabung dari beasiswa akan sangat sulit.
-
percaya diri, self convidence kamu harus tinggi (atau istilahnya lebih baik narsis daripada minder, iya ga) karena kamu adalah penerima beasiswa dan pikiran serta tenaga diperlukan oleh advisor kamu.

(next for the part 2)

Konversi Energi

kalau kamu orang teknik mesin, maka pasti kamu tahu kalau di teknik mesin itu terbagi didalam 2 (dua) bagian besar yakni manufaktur dan konversi energi. betul kan,,

nah untuk Konversi energi bisa dilihat bagan dibawah ini

bagan konversi energi ala maul

ini yang ada di dalam pikiranku sewaktu kuliah dulu, jadi KE (Konversi Energi) itu bisa dibagi dalam 3 kategori lagi yakni Power Plant atau pembangkit tenaga listrik, refrigerasi atau teknik pendingin dan fluida.

I will married

our ring

setiap orang akan memikirkan mengenai pernikahan, sekarang adalah saatnya saya memikirkan hal tersebut

Everybody who has dream on married will get into it, by marry you will get serenity on a life. I term of serenity people were seeking in religion way and I believe by married my soul will calm.

I have found someone who will be my wife forever, she is a though woman ever I know, she has something that I do not have, its really completing each other.

we have our own dreams and we will rise it in our times together.

may Alloh SWT bless us together in our next journey.

PLTU akan kah cocok untuk indonesia

PLTU dan Polusinya

pemanfaatan sumber daya alam yang ada di Indonesia memberikan peluang untuk kita mengambil sebesar besarnya sumber daya alam tersebut, didalam tahun ini pemerintah telah melakukan awal pembangunan berbagai pembangkit listrik yang berbahan bakar batu bara, proyek 10.000 MW akan memanfaatkan sebagian besar berbahan bakar Batu Bara.

diseluruh indonesia akan dibangun PLTU, dan pembangunana di Jawa lebih besar lagi dikarenakan industri yang ada di Indonesia rata-rata berada di jawa. untuk memberikan daya kepada industri dan masyarakat maka di daerah Indramayu, pelabuanratu dan awar-awar dibangun PLTU yang akan dioperasikan oleh PJB.

pemakaian batu bara untuk PLTU akan meningkatkan harga dari batu bara itu sendiri, sama halnya dengan sumber energi lainnya seperti solar dan gas yang terus meningkat akan menaikkan harga. dengan peningkatan permintaan batu bara maka para produsen batu bara indonesia akan diminta untuk meningkatkan produksinya sehingga kebutuhan dari PLTU di seluruh Indonesia akan terpenuhi, oleh kerena itu diperlukan regulasi dari pemerintah soal pengaturan industri tambang batu bara ini. jika dilepaskan oleh mekanisme pasar maka PLTU yang telah dibangun akan mengalami kesulitan dalam men-supply bahan bakar atau bisa dikatakan antara PLTU akan terjadi persaingan dalam memperebutkan batu bara.

disisi lingkungan akan terjadi peningkatan sulfida SOx dan COx serta zat lain hasil pembakaran masuk ke lingkungan. issue yang sedang hangat adalah global warming, tak ayal bangsa kita akan menjadi salah satu bagian besar dari pemanasan dunia. ini akan terlihat dari kulitas udara, tanah dan air hasil dari pembuangan limbah PLTU. maka didalam melakukan perencanaan pembangunan PLTU harus dipikirkan bagaimana waste tersebut kembali di kelola agar limbah yang masuk kelingkungan terkurangi kandungan racunnya.

sesungguhnya ada cara yang paling innovative didalam menghasilkan energi listrik selain menggunakan PLTU yakni PLTN atau pembangkit listrik tenaga nuklir, teknologi nuklir sudah sangat maju sedangkan taknologi PLTU sudah menuju kadar staknan atau perkembangannya tidak rapid.

indonesia membutuhkan energi listrik yang besar dan nuklir akan memberikan solusinya

pindah kantor

PLN Enjiniring

hari ini, rabu 4 juni 2008, saya pindah kantor ini bukan artinya saya pindah kerjaan namun departemen saya akan pindah kantor, yang awalnya di KS Tubun gedung PLN jasa enjiniring, pindah ke daerah jalan kiyai Maja, dekat denan rumah sakit pusat pertamina.

perpindahan ini karena ruangan yang tersedia untuk departemen pembangkit kurang memadai sehingga diperlukan perluasan. yah, walaupun begitu suasana kantor tampaknya tidak akan berubah karena orang yang bekerja tetap sama. jika saya bisa memilih saya akan memilih suasana kantor yang ruangannya tidak ada satupun yang merokok di dalamnya.

kebiasaan yang sangat negative bagi suasana kantor disini. pertama kali saya bekerja disini saya pun kaget dengan lingkungan para perokok, heran saja karena kedisiplinan kurang ditegakkan, kata manager yang penting bertanggung jawab. hah, masak sih harus orang sakit dulu kemudian bertanggung jawab untuk membiayai rumah sakit, ya gak mungkin lah. saya akan bertindak akan sedikit keras mulai saat ini terhadap orang yang merkok disamping saya, ,

doakan saya ya..
