Lengshui Ji refrigeration system basically by what composition

1, the compressor.
2, the condenser: the condenser in the cooling process plays a role in the output of heat and allow the refrigerant to be condensed. The high-pressure superheated vapor discharged from the refrigeration compressor enters the condenser and transfers all the heat it absorbs during operation, including the heat absorbed from the evaporator and the refrigeration compressor to the surrounding medium (water or Air) away; refrigerant superheated steam re-condensed into a liquid. (Depending on the cooling medium and the cooling mode, the condenser can be divided into three categories: water-cooled condenser, air-cooled condenser, evaporative condenser.)
3, the reservoir: the reservoir installed in the condenser, and the condenser drain pipe is directly connected. Condenser refrigerant liquid should be unimpeded into the reservoir, so that you can take full advantage of the condenser cooling area. On the other hand, when the heat load of the evaporator changes, the required amount of the refrigerant liquid also changes, and the accumulator functions as a refrigerant for regulating and storing the refrigerant. For small chiller refrigeration system, often not equipped with liquid storage device, but the use of condensers to adjust and store the refrigerant.
4, the dry filter: in the chiller cooling cycle must be to prevent moisture and dirt (oil, iron, copper) and other sources of moisture is mainly added to the new refrigerant and lubricants contained in trace water, Or the moisture that comes from entering the system when the system is inspected. If the system does not rule out the water clean, when the refrigerant through the throttle (thermal expansion valve or capillary), due to pressure and temperature drops will sometimes solidify into ice water, the channel obstruction, affecting the normal operation of refrigeration equipment. Therefore, in the chiller cooling system must be installed dry filter.
5, thermal expansion valve: thermal expansion valve in the chiller cooling system is both flow control valve, but also refrigeration equipment in the throttle, which is installed in the refrigeration equipment in the dry filter and evaporator, and its sense of The bulb is wrapped around the outlet of the evaporator. Its main role is to make high-pressure refrigerant liquid at room temperature through the thermal expansion valve when the throttle buck, into low-temperature low-pressure refrigerant wet vapor (most of the liquid, a small part of the steam) into the evaporator, vaporization in the evaporator Endothermic, and cooling to achieve the purpose of cooling.
6, the evaporator: Evaporator is dependent on refrigerant liquid evaporation (in fact, boiling) to absorb the heat of the cooling medium heat transfer equipment. Its function in the refrigeration system is to absorb heat (or output cooling capacity). In order to ensure that the evaporation process can not be indiscriminate and lasting, must continue to use the refrigeration compressor will be vaporized gas away to maintain a certain evaporation pressure.
7. Refrigerants: Most of the industrial chillers used in the modern industry use R22 or R12 as the refrigerant. Refrigerant is the active refrigerant in the refrigeration system, its main role is to carry heat, and change the state to achieve endothermic and exothermic.
