Water Chiller

Chillers

 

A chiller is a cooling system that removes heat by circulating heat-absorbing a refrigerant through a series of mechanisms through which the heat is released. The essential components of a chiller are a compressor, condenser, expansion valve, and evaporator. They work in unison to circulate a refrigerant that removes heat from a process, operation, or space.

There are several different types of chillers, each of which has a different process for removing heat. All chillers use air or water as a cooling method. For example, air cools a chiller system using fans, while a water-cooled chiller circulates water with a cooling tower.

Aside from the two cooling processes, chillers are further differentiated by the type of compressor they have. Compressors in all chillers have the same function: to compress the refrigerant and increase its temperature and pressure before it moves on to the condenser.

Refrigeration Types of Water Chillers                                                              

Air Cooled Chillers

Air cooled chillers use shell and tube evaporators to exchange heat between water and refrigerant. The refrigerant system absorbs the heat in the water. After cooling the water, the heat is brought to the condenser through the compressor, and then dissipated to the outside air by the cooling fan.

Characteristics of air-cooled chillers:

  • The air-cooled chiller does not need to be connected to a cooling tower, and is suitable for environments with poor impurities. (Impurities are easily mixed in the cold water tower, and the dust will cause the cooling water circulation circuit to be blocked, resulting in a decrease in cooling capacity).
  • Air-cooled chillers are most suitable for areas with poor water quality, which can save other accessories such as cold water towers.
  • The use of large-capacity condenser makes it easier and more convenient to operate.
  • The floor space is reduced to a greater extent, and the installation is very convenient.
  • The air-cooled chiller adopts the design of the upper air outlet.

Water Cooled Chillers

The water-cooled chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat in the water. After the water is cooled, the heat is transferred to the shell-and-tube condenser through the compressor. After the water absorbs heat, the heat is taken out to the external cooling tower through the water pipe for heat dissipation.

Characteristics of water-cooled chillers:

  • The box-type evaporator has a built-in automatic water replenishment device, which is convenient for installation and maintenance, and is suitable for special occasions such as large temperature difference and small flow.
  • The water-cooled condenser uses the latest high-efficiency external thread copper pipe, which has a large heat dissipation capacity. It adopts the latest CAD/CAM processing technology and cooperates with CNC machining center to make it, with compact structure, high efficiency and energy saving.
  • Configuration of industrial chiller unit: Equipped with single-chip control system, built-in compressor drier filter and expansion valve, maintenance hand valve interface and other devices to ensure reliable and safe operation of the machine, and easy maintenance.
  • The multi-function operation panel of the industrial chiller is equipped with an ammeter, control system insurance, compressor switch button, water pump switch button, electronic temperature controller, various safety and security fault lights, and unit startup and running indicator lights, which are simple to operate and easy to use.

Working Principle of Chiller                                                                              

The whole working principle process of industrial water chiller can be roughly divided into three parts: water circulation system, refrigeration circulation system and main control system. The water circulation system is also a part that directly reflects the function of the industrial water chiller. It transmits the cold water to the equipment that needs to be cooled, and the cold water absorbs the heat of the equipment and then transmits it back. The refrigeration cycle system is a process of cooling the cold water that absorbs heat. The refrigerant sublimates and then compresses to bring the heat in the cold water to the outside for dissipation. The main control system is the part of power control and internal structural components control.

Basic Structure of Chiller                                                                                  

Industrial water chiller consists of compressor, condenser, evaporator, expansion valve and other accessories.

  1. Compressor: in the industrial water chiller system, the compressor is the power to ensure refrigeration. The compressor is used to increase the pressure of the refrigerant in the system and make the refrigerant circulate in the refrigeration system to achieve the purpose of refrigeration.
  2. Condenser: high temperature and high pressure Freon of the refrigeration system enters the condenser after coming out of the compressor, releases a lot of heat to the cooling medium, and then is cooled and liquefied.
  3. Evaporator: when the Freon liquid of the refrigeration system enters the expansion valve for throttling and is sent to the evaporator, it belongs to the vaporization process. At this time, it needs to absorb a lot of heat to gradually reduce the valence and mass temperature to achieve the effect of refrigeration and cooling.
  4. Expansion valve: in the refrigerant system flow chart of the industrial water chiller, we found that there is a small part between the outlet of the condenser and the inlet of the evaporator, which is called thermal expansion valve. It is a throttling and depressurizing part to reduce the condensation pressure of the refrigerant to the evaporation pressure. Therefore, its role in the refrigeration system is essential. It is connected with the refrigeration compressor, evaporator, condenser It is also called the four components of the refrigeration system.
  5. Other accessories: including drying filter and high and low pressure controller. The drying filter is non detachable. The internal structure adopts molecular sieve structure, which can remove a small amount of impurities and water in the pipeline, so as to purify the system. The high and low pressure controller plays a protective role in the refrigeration system.
