<p>The thermal plant for heating and cooling has evaporator, compressor, liquefier and throttle valve, together forming a heat pump unit. The liquefier is connected to the load circuit, and the plant can be operated simultaneously as heating and cooling plant. The heat exchanger (7) is connected downstream of the evaporator (1) of the heat pump (5) and the room air is directed over the heat exchanger. Alternatively the water to be cooled is passed over the heat exchanger. This air or water can be directed also over the evaporator (1). A heat exchanger (8) can be connected to evaporator (1) at upstream end. This heat exchanger collects solar energy and transfers it to the fluid flowing through heat exchanger.</p> |
