Liquid refrigerant injection valve is a very effective method for controlling subcooling & the compressor discharge temperature
Liquid refrigerant injection valve working as compressor protector to cool compressor when discharge gas temperature is too high
Liquid refrigerant injection valve should be installed when AC/refrigeration unit works in high ambiment temperature (T3)
4KW(R410a) reversing valve for changing liquid refrigerant flow direction or defrosting in refrigerated cabinet or deli display
5/8 solder (1.9m3/h) refrigerant Solenoid Valve is installed in liquid lines of air dryer machine or freezer dryer machine
30L Liquid Refrigerant Receivers with 7/8 valve are suitable for use with HFC and HCFC refrigerants and their associated oils

60L liquid refrigerant tank with valve installed in heat pump water heater for swimming pool
Liquid injection kits can inject liquid refrigerant according to suction temperature to avoid too high suction temperature
Liquid injection Kits are used to inject refrigerant into the suction line of system to reduce the high discharge temperature
20HP liquid injection Kits main functions include refrigerant injection into the suction line and two-stage refrigeration plant.
refrigerant distributors distribute liquid refrigerants from the thermostatic expansion valve to individual sections of evap.
Liquid injection Kits is universal, for R134a, R404A, R507A, R407C and R23, R407A and R407F other refrigerants upon request
Liquid refrigerant Receivers with 1-1/8 valve are installed after the Condenser and before the Liquid Line Filter-Drier
optimal amount of refrigerant in a refrigeration system
Determination of the optimal amount of refrigerant in field assembled refrigeration systems by use of a sight glass installed in liquid line is often misleading and unreliable. This is attributed to interferences to laminar flow of the refrigerant in the sight glass by ice formation in the expansion valve, vaporization of the liquid in pipes and foreign particles. Due to these interferences refrigeration systems may be overcharged or undercharged with the refrigerant. Measurement of temperatures and pressures at the inlet and exit of an evaporator may provide an accurate and reliable criterion of establishing the optimal amount of refrigerant in a refrigeration system. Using Rayleigh''s method of dimensional analysis, a mathematical model that expresses the evaporator cooling rate for field assembled refrigeration systems in terms of physical properties of the evaporator and the thermodynamic properties of refrigerant R134 a was developed. The model expresses the optimal amount of refrigerant in a refrigeration system corresponding to the maximum cooling rate.
