Single head cold water machine with double head cold water machine the difference

a, single stage refrigeration system

1, the single stage refrigeration cycle is refers to the refrigerant in the refrigeration system through austerity, condensation, save, transpiration, four process is complete the cycle of single-stage chiller, which meet the intention of refrigeration. Single stage refrigeration cold water machine is a type of the machine is widely used, it can be used in fabrication, electronics, refrigeration, pharmaceutical and industrial production process, etc.

2, transpiration, single-stage tightening machine, condenser, saving valve and other affiliated equipments, etc, to each other through the pipe connection into a closed system. Among them, the transpiration is transporting equipment, the cooling capacity of liquid refrigerant transpiration after absorbing heat cooling objects to complete refrigeration; Tightening machine is the heart of the system, plays a suction, austerity, output the effect of the refrigerant vapor; Condenser will squeeze machine high temperature liquid refrigerant vapor condensation into full discharge; Save valve on refrigerant save antihypertensive effect control and regulate the province into the transpiration refrigerant liquid flow, and the system is divided into the high side and the low voltage side.

2, two-stage refrigeration system

1, the double-stage refrigeration cold water machine is developed on the basis of the single stage refrigeration cycle, the tightening process is divided into two period, from the evaporation of refrigerant in low pressure steam tight cylinder to the center of pressure, after center cooling again into the high pressure cylinder, tightening the condensing pressure into the condenser. General transpiration temperature in - 25. 7℃~- 49. 8 ℃, should adopt two-stage tightening machine for refrigeration.

2, two-stage refrigeration system by transpiration, two-stage tightening machine, condenser, central cooler, save valve and other affiliated equipments, etc, to each other through the pipe connection into a closed system. Among them, the central cooler using a liquid cooling in the center of pressure vaporization heat, cooling level low pressure discharge of superheated steam, and fell by suction temperature of high voltage level, also cools the high pressure liquid refrigerating agent together.

summing up the above, a temporary in industrial cold water machine, unipolar and multilevel refrigeration is difference: the number of stations and tightening machine, cold water machine can be divided into single-stage refrigeration and multilevel refrigeration types such as refrigerator, and multipolar refrigeration system can regulate the cooling power of cold water machine and a refrigerator.
