THERMODYNAMIC SYSTEM FOR HEATING, AIR CONDITIONING AND HOT WATER PRODUCTION

摘要

Thermodynamic system for heating and cooling a building, and for producing domestic hot water, comprising a refrigerant circuit, a compressor device (14), an expander (10), a heat exchanger with an external medium ( 12), a heat exchanger for heating and cooling (22) of the building, and a heat exchanger for a hot water tank (24), this circuit comprising in a loop successively the expander (10) being able to work in both direction of circulation, the exchanger with an external medium (12), the compressor device (14) being able to work in both directions of circulation, and a group of heat exchangers including the heat exchanger and air conditioning (22) and the exchanger of the hot water tank (24) arranged in parallel, this group comprising a first three-way valve on the inlet (20) and a second three-way valve on the outlet (26), being able alternatively to put in the cir cooks the heating and air conditioning heat exchanger (22) or the hot water tank heat exchanger (24).
