KVP
The KVP is mounted in the suction line after the evaporator and is used to:
1. Maintain a constant evaporating pressure and thereby a constant surface temperature on the evaporator. The regulation is modulating. By throttling in the suction line, the amount of refrigerant gas is matched to the evaporator load.
2. Protect against an evaporating pressure that is too low (e.g. as protection against freezing in a water chiller). The regulator closes when the pressure in the evaporator falls below the set value.
3. Differentiate between the evaporating pressures in two or more evaporators in systems with one compressor.

Cold Rooms
KVP is a mechanical evaporator pressure regulator used where the refrigeration system needs stable evaporating pressure at the evaporator. In cold room applications, it is especially relevant where installers need to keep evaporating pressure at the required level, protect the system against excessively low evaporating pressure, or separate evaporating pressure levels between multiple evaporators.
It is particularly relevant in cold room systems where pressure regulation supports stable operation, compressor protection, and correct refrigerant control under changing load conditions.
