What is expansion valve?
The expansion valve represents the point of separation between the high pressure and low pressure sections in the refrigerant circuit.In order to achieve optimum cooling capacity in the evaporator, it is installed in upstream of the evaporator, and the refrigerant flow is controlled by it as temperature changing.
EBI Part accept customized expansion valves as your requirement.
How do they work ?
The liquid refrigerant arriving through the receiver drier from the condenser, and injected into the evaporator. The evaporating refrigerant releases evaporation cold and make temperature dropping. In order to optimum cooling capacity in the evaporator, the refrigerant flow is controlled by the expansion valve depending on the temperature.
If the refrigerant temperature increases at the end of the evaporator, it expands in the expansion valve. So that an increase of the refrigerant flow (injection quantity) to the evaporator.
If the refrigerant temperature lowers at the end of the evaporator, the volume decreases, and it reduces the refrigerant flow to the evaporator.
