Guide to buying the DamaTajhiz water-cooled chiller

The most prominent companies in the world create screw, reciprocating, centrifugal, or scroll compressors, which are used to design and manufacture all different types of Water Cooled Chillers by the orders and requirements of the recognised buyers. It depends on the client's order from businesses like Copeland, Danfoss, Bitzer, etc. what kind of compressor brand is used in Water Cooled Chillers. The cold water compression chiller, whose performance is based on the condensation refrigeration cycle, is the driving force behind providing cold water for industrial refrigeration systems and air conditioning with a temperature of 7 degrees Celsius.
In the facilities industry, Water Cooled Chillers provide cold water for cooling coils in fan coils and air conditioners. When compared to air-cooled compression chillers, it can be said that the efficiency of water-cooled chillers is higher. When reviewing the technical specifications and purchase order, there is a wide range of topics related to Water Cooled Chillers, so if you want more information or answers to any questions you might have, you can get in touch with our experts in the sales engineering department of DamaTajhiz Group's air conditioning equipment.

The equipment used in the construction of DamaTajhiz Water Cooled Chillers

In general, the main components of the Damatajhiz Water Cooled Chiller are:

• Compressor

The main task of the compressor in the Damatajhiz Water Cooled Chiller is the process of compressing the refrigerant gas in a vapour compression refrigeration cycle.
By condensing the refrigerant gas in the compressor, the energy required to circulate it in a closed cycle is created.
Various compressors can be used in Water Cooled Chillers according to the required capacity, the type of refrigerant used, the use of the project, the conditions of the installation site, and other factors.
It should be noted that, due to the uneconomical use of Water Cooled Chillers in low capacities, usually screw and centrifugal compressors are used in these types of chillers, when their estimated production capacity is much higher.

• condenser

Condenser rejects the total heat transferred to the refrigerant due to the condensation process in the compressor as well as the heat caused by the evaporation process in the evaporator to the outside environment and finally leading to condensation of the refrigerant vapour.
In the water condenser, which is usually designed and manufactured in the form of a shell and tube heat exchanger, the refrigerant gas coming out of the compressor enters the converter shell with a high flow rate. It is placed in contact with and adjacent to the cold walls of the pipes, where the flow of cool water produced by The cooling tower passes through them and in this way the heat of the refrigerant gas is transferred to the water of the cooling tower and the refrigerant gas turns into a liquid.

• expansion valve

The expansion valve is installed in the liquid line between the condenser and the evaporator inlet.
The expansion valve is located opposite the compressor in the refrigeration system. While the compressor raises the refrigerant pressure and circulates it in the system.
The expansion valve reduces the pressure of the refrigerant liquid coming out of the condenser and prepares the refrigerant to enter the evaporator and absorb heat from the evaporator environment.
The two important tasks of this valve can be mentioned (1- reducing the pressure and temperature of the refrigerant and 2- controlling the flow rate of the liquid entering the evaporator by the temperature of the gas exiting the evaporator).
Expansion valves are designed and manufactured in two types, mechanical or thermostatic and electronic.
In compression chillers with high capacities, to control the refrigerant flow more accurately and reduce its pressure and temperature, and as a result, the use of an electronic expansion valve is recommended.

• operator

The process of heat absorption and refrigerant evaporation is the last thermodynamic process in the refrigeration cycle, which ultimately leads to the cold water produced by the Water Cooled Chiller, which is an evaporative evaporator that, in the form of a heat exchanger, transfers the heat of the water flow to the incoming cold refrigerant. , while reducing the water temperature, it also causes the complete evaporation of the coolant.

Usually, two types of heat exchangers are used as evaporators in Water Cooled Chillers, which are:

1. Shell and tube heat exchanger:

This converter is one of the common converters used in air conditioning and industrial cooling devices and consists of a cylindrical steel shell with several copper pipes inside.
In the shell and tube evaporator, the refrigerant liquid passes through the copper tubes and the water flow to cool the inside of the shell in contact with the outer surfaces of the U-tube. By absorbing heat from the walls of the pipes, the coolant reduces the temperature of the pipes and the water in their flow. While reducing the temperature of the water, the refrigerant also evaporates completely after absorbing the heat.

2. plate heat exchanger:

This type of heat exchanger is equipped with thin metal plates that are used to transfer heat between cold and hot fluid flows.
The most important advantage of the plate evaporator compared to the shell and tube evaporator is that the cold flow of the refrigerant and the hot flow of water are exposed to a greater surface area for heat exchange. (Water and coolant are completely distributed on the metal plates.)
As a result, the heat transfer is better and the water cools down in a shorter time. In other words, to produce the same volume of cold water, the dimensions of a plate evaporator will be much smaller than the dimensions of a shell and tube evaporator.
Despite the higher thermal efficiency of plate exchangers than shell and tube exchangers, they are mostly used as evaporators in chillers. Because the circulating water often has a lot of hardness and solutes, and due to the close distance between the metal plates of the plate exchangers, which have a shorter life, it may become a problem in a short period. In addition, if the plate converters are damaged, they cannot be changed and must be replaced with a new converter.

Important points before buying the Damatajhiz water cooled chiller

The following points should be taken into consideration when purchasing a DamaTajhiz cooling water chiller:

1. It is not advised to use water cooled chillers in cities and areas with high summer humidity levels because cooling towers must be used as a complementing device next to them.
2. According to the orders of reputable buyers, centrifugal, reciprocating and screw-type Water Cooled Chillers with very high capacities may be produced.
3. Typically, the compressors used in the Water Cooled Chiller devices come from reputable and original manufacturers like Copeland, Bitzer, etc.
4. To ensure that the required cold water compression chiller will fit through the engine room door and be transported to the foundation where it will be installed, be careful to order the correct measurements of the chiller.
5. In addition to placing the order for the required cold water compression chiller, the precise weight of the appliance was also known, allowing the company's experts to provide a machine and crane that would be adequate for loading and unloading this appliance.
6. DamaTajhiz manufactures Water Cooled Chillers based on the specifications of the customer, using a range of R134 or R22 refrigerants.
7. According to the type of order from the respected customer, there may be a change in technical requirements and a requirement for using specialised equipment in the design and construction of Water Cooled Chillers (such as the installation of steel evaporators or the creation of special condensers). Please get in touch with our professionals in the DamaTajhiz collection's air conditioning division to let them know about the adjustments and to learn more about the new costs.
8. Consider the discrepancy between the chiller's nominal capacity and its real capacity when selecting a Water Cooled Chiller.
9. The use of quality and original brand compressors (assurance of authenticity) Brand) has been mentioned as one of the determining factors to minimise the difference between the nominal capacity of the chiller and its actual capacity. Other determining factors include the length, diameter, number, and type of copper pipes used in the condenser and evaporator.
10. With choices like installing unique PLC system equipment, the ability to install apps and remote control, and the installation of more intelligent control equipment, the device can be made and designed in a customised manner.
