Installing Two-Temperature Valves

Installation Of Two-Temperature Valves

Pressure-operated two-temperature valves should be installed in the suction line of the warmer evaporators. Their work usually does not affect the distance from the evaporator. Thus, they can be connected anywhere on the suction line. Often, the valves of this kind are found in carbonated water. Solenoid valves for two temperature operations are installed in the liquid line on Wanner evaporators.

This type of installation can be improved by installing a check valve on the suction line of the cold evaporator. This prevents the pressure rise of gases from backing up into it. In addition, the expansion tank should be installed near the condensing unit. It should be connected between the compressor and the main suction line. This will reduce fluctuations (rapid up and down changes the low pressure side.

In most code plants, two-temperature valve and check valve must be mounted near the condensing unit. Expansion tank must be mounted on the basis of condensing units...
