This connector is a base connector used for modular heat pumps and contains typical variables that may be measured in the modular heat pump models.
Typically, a heat pump consists of four main components: A compressor, a condenser, an expansion valve and an evaporator. Furthermore, considering the perspective of the refrigerant used in the heat pump, the evaporator is the source and the condenser is the sink. Therefore, it is assumed that the heat pump has six sensor positions:
Four different sensors are proposed at refrigerant's side:
Three different sensors are proposed at source's and sink's sides:
