heating (35 ºC), radiator heating (40 ºC – 50 °C) or with additional heating up in the boiler as hot water or steam. After the working fluid delivered its heat on medium it exits from the condenser (point 3) and enters the liquid container. The purpose of this tank is to balance pressure and volume of media in the entire line of heat pumps.
