<p>An automatic air-conditioning and/or hot water production system, comprising at least three heat exchangers 2,3,4, a compressor 1 and valve means 5A-F, 6 for the selective connection of the exchangers to each other and with the compressor. A first exchanger 3 is suitable for producing hot water for an auxiliary circuit, a second exchanger 4 for conditioning the environment and the third exchanger 2 is connectable selectively by said valve means to one of the first two; said valve means being suitable for connecting the exchangers between each other and with the compressor in such a way that, depending on the state of operation of the system, one of the exchangers is always blocked and the other two work, one as a condenser and the other as an evaporator, said first exchanger always working as a condenser. <IMAGE></p> |
