    SYSTEM DIAGRAM Dimensions and pipe F1126 consists of heat pump, immersion heater, circu- lation pumps and control system. F1126 is connected connections to the brine and heating medium circuits. In the heat pump evaporator, the brine (water mixed with anti-freeze, glycol or ethanol) releases its energy to the refrigerant, which is vaporised in order to be compressed in the compressor.
