The air cooled chiller offers the most competitive price

Compression chillers are currently in high demand among consulting engineers and buyers due to their efficiency, affordability, variety of sizes, excellent performance, and ease of service and maintenance. The Compression Chiller Buying Guide helps you choose a good compression chiller that works well. If you want to buy the best compression chiller, read the article below to learn 10 important tips for choosing and buying the best air conditioning compression chiller.

How to choose the most suitable type of chiller

The first factor to be considered before purchasing any type of chiller is the type of unit (refrigerated or air-cooled chiller), the actual cooling capacity and then the amount of electricity required by the chiller; buyers should first select the type of chiller according to the specific facilities and conditions of their project and then obtain detailed information on things such as the selection of the appropriate capacity of the unit, the amount of electricity required (power branch) and the amount of electricity consumed, so that they can make a correct choice and have suitable equipment.

In short, air-cooled chillers are installed outdoors, usually on the roof of the building. These units do not require a water cooling tower or a constant supply of water, and they perform optimally in very hot and humid weather. On the other hand, air-cooled chillers require relatively more primary power distribution than water-cooled compression chillers.

To help you choose the best compression chiller, we refer you to the comparison table between air-cooled and water-cooled chillers in similar weather conditions.

Dear Customers, you can choose the best compression chiller you need, according to the specific possibilities and limitations of your project, at every stage of reading this article while contacting the experts of the specialized group of DamaTajhiz. Our colleagues in this specialized group are always ready to answer you, dear customers.

Determination of compressor type, capacity and authenticity of original refrigeration brand

The second important thing that buyers should pay attention to is the accurate calculation of chiller capacity and the type of compressor. The compressor is actually the beating heart of any compression chiller, which should be done before buying a chiller of its type (scroll, screw, piston, etc.), the right number and capacity, as well as the authenticity of the compressor manufacturing company (specification of the original compressor from its fake model) so that you can choose and buy the best compression chiller.

A collection that can honestly and impartially help you in choosing the right capacity of the compression chiller and the type of compressor (from the most reliable companies in the world that have the product authenticity code), our consultants and engineers in the DamaTajhiz collection are equipped Our colleagues are always ready to give you a competent response regarding the purchase of the best type of compression chiller to you, dear buyers.

Ensuring the high quality of internal mechanical and electrical equipment of the chiller

Before choosing and buying your compression chiller, in addition to the above points, you should check the authenticity of the brand and the manufacturer of the mechanical and electrical equipment of the unit, such as the compressor, contactors, control system, control circuit, relays, electric and manual valves, etc. He was fully informed about the quality and the manufacturing process of the unit.

There are companies that have used parts and equipment with apparently authentic names, but counterfeit ones during the construction of the equipment, which in the near future and after the operation of the equipment will cause irreparable and irreversible financial damage to the respected buyers.

Warranty of the most comprehensive after-sales service

A very important point to consider before buying a compression refrigeration unit is to buy it from a reliable company that not only guarantees the quality of the unit and the authenticity of its internal mechanical and electrical equipment, but is also responsible and committed to providing a warranty service. And after-sales service is also decent.

Due to the specialisation of the working system of these appliances and of the parts used in them, the selling company, in addition to being able to supply parts, must have the necessary expertise for the repair and maintenance of chillers throughout the country, so that in the event of a malfunctioning appliance, the buyer can benefit from its services in the shortest possible time by presenting the product warranty card.

Reliable and large centres are always committed to providing very favourable warranty services and a proper response to buyers, and are always taking steps to improve their services in this regard (by surveying buyers).

DamaTajhiz Collection, as the first and most respected specialised reference for the sale of all air conditioning equipment, with the benefit of expert forces, has always tried to provide decent warranty and after-sales services for all its products, including compression chillers. in such a way as to respond to the needs of customers in the shortest possible time.

Pay attention to the coefficient of performance of chillers (C.O.P)

The coefficient of performance of a compression chiller, usually referred to as COP, simply indicates the amount of cooling produced by the chiller per unit of electrical energy consumed, and the higher this number is, the more efficient the compression chiller. When choosing and buying a compression chiller, you should pay attention to the esteemed buyers.

Is cheapness always a positive factor?

When choosing and buying a compression refrigeration unit, you sometimes come across companies that sell their units cheaper, while in addition to not using quality and original parts and equipment inside the unit, even after At the time of selling the unit, they do not answer the buyers to solve the consecutive defects and subsequent problems (after-sales service) and they always have excuses to justify their work, so buyers should be very careful to avoid making a wrong choice and damage. Don't take this seriously in the future.

Since the types of compression chillers offered in the DamaTajhiz have a 24-month golden warranty on the unit with the possibility of replacing the compressor and a 15-year comprehensive after-sales service (with the benefit of expert teams) in different cities of the country, this collection, as the first specialised and reliable reference for the sale of all air conditioning equipment in the country, is ready to provide all types of compression chillers with the best materials, using original parts and with the best quality and the most reasonable price.

Ensure that all the components of the chiller are new!

One of the main points when buying a compression chiller is that the buyer should pay special attention to the new and healthy condition of the compression chiller and all related parts and equipment as the heart of the cooling system of the building and project, so that the second-hand compression chiller with used parts and buy a painted instead of a new compression chiller.

Unfortunately, there are only a few companies today that refurbish used chillers by using unsightly and unpleasant methods such as replacing defective parts and burnt electrical equipment, repainting and re-insulating the rotten body of the unit and rebranding it as a new chiller. that buyers should do the utmost care and investigation in this regard.

As it is very difficult and complicated to diagnose this problem and requires skilled and specialised personnel, it is recommended that you make your purchase only from very reputable and well-known centres and have peace of mind about the prices and the assurance of the authenticity of the goods. And with a golden guarantee and extensive after-sales service throughout the country, you will experience a satisfying and wise purchase.

Choice of chiller capacity in accordance with requirements

Sometimes there are companies that have been importing only a few chillers of a certain capacity for a long time, or have already produced them in their country and have them in stock. If you make a purchase enquiry to these companies, they will only think about selling their unit without considering the engineering calculations and specific conditions of your project, and will insist on selling the same capacity and model of unit. Therefore, you should have detailed information about the type and precision of the compression chiller you need and then proceed to purchase the compression chiller.

Buying a unit with a higher capacity, in addition to imposing a higher initial cost on the buyer, will cause the buyer to pay a lot of running costs (paying the cost of electricity), and vice versa, buying a compression chiller with a lower capacity than the project needs, in addition to the unit not responding and not providing proper air conditioning, will cause subsequent problems, including serious and irreparable financial losses to the unit.

Furthermore, at the time of selecting and inquiring about the purchase of the compression chiller you need, the nominal capacity of the chiller should not be the selection criterion and you should pay attention to and emphasise the actual capacity of the chiller in the conditions of your project. (especially for air cooled chillers)

Is there a need for compression refrigeration equipment?

As mentioned above, chillers are designed and supplied in a wide range of capacities and you should make the right choice according to your needs. Typically, compression chillers are manufactured in an integrated manner up to a capacity of approximately 500 tonnes of cooling. For example, suppose the cooling capacity required for your project is 200 tonnes of real cooling. Many European and Iranian brands produce this unit in an integrated manner. Of course, instead of one unit, you can use two chillers with 100 tonnes of real cooling capacity. Choose them and use them together in a modular way. There are advantages and disadvantages.

When using several chillers in a modular way, since the chillers are usually not working at peak load, sometimes one unit can meet your needs and the second unit does not need to be started frequently. This will increase the life of the chillers. In addition, if one chiller fails, the second compression chiller kicks in as a back-up, ensuring the relative satisfaction of the occupants throughout the building.

In addition to these advantages, the initial cost of buying several units is much higher than buying one. In addition, the purchase of two compression chillers requires more space for their installation and operation. Of course, it should be mentioned that today's integrated chillers are equipped with several compressors and several separate cooling circuits, called modular chillers, which practically overload a compression chiller in stages and with the advantages of several chillers, but in the form of a single chiller. It works seamlessly.

Which brand of water chiller should we buy?

Iran's air conditioning market today consists of a variety of foreign and domestic brands; Italy is one of the most prominent and leading countries in the chiller industry. In addition to Italy, chillers from Iran, China, Malaysia and Thailand are also very popular today. Mendi is an experienced and trained staff, equipped with modern machinery and equipment, and in accordance with international plans and standards, they are engaged in manufacturing all kinds of compression chillers in Iran.

The point that should be taken into consideration when choosing the capacity, type of brand and purchasing a compression chiller is the initial cost that you will pay to purchase the compression chiller required for the project. Normally, European compression chillers are much more expensive than chillers of the same capacity manufactured in Asian countries (Iran, China and Thailand), and chillers manufactured in Asian countries are usually a little more expensive or in the same price range as high-quality compression chillers manufactured by the company.

It is necessary to explain that a major part of this price difference between foreign chillers (European and Asian) and high quality chillers produced in Iran is only due to the reduction of costs related to imports, as well as the low price of energy and the lower cost of personnel and labour in Iran. .

Closing remarks

Choosing the right compression chiller for a building is very important for two reasons; First, the amount of cooling required for an environment in the summer has a direct relationship with the comfort and well-being of the residents, and the lack of proper ventilation and providing the desired temperature in the hot seasons for a space will practically make life in that place unbearable.

Second, compression chillers are a very important, capital and expensive equipment in a building, so choosing the correct type and capacity of the device should be done based on the specific facilities and conditions of the project and after performing detailed engineering calculations in this regard in order to avoid incurring costs. Additional costs and heavy financial losses to the buyers and users of the project will be completely prevented in the future.

Fortunately, today many technical and engineering companies are active and working in this field in Iran, which provide engineering calculation services and expert advice regarding the selection of suitable compression chiller with real capacity to the buyers.
