Heat recycling system with nighttime cooling recovery

Abstract

The invention concerns a heat recycling system comprising at least one exhaust air heat exchanger mounted inside the exhaust air flow of a ventilating and/or air-conditioning plant, especially of a building or a portion of a building, and at least one outside air heat exchanger mounted within the intake air flow of such unit, whereby the heat exchangers are integrated within the circuit, whereby for the production of cold, especially nighttime cold from outside air at least one partial circuit can be segregated from the integrated circuit, in which circuit is mounted one of the heat exchangers, especially an exhaust air heat exchanger, through which the outside air can be channeled in order to cool the fluid in said partial circuit, whereby the partial circuit features at least one heat exchanger, through which the cold so recovered can be channeled into a cooling circuit. The invention further concerns a process for the recovery of nighttime cold out of outside air by means of an integrated circuit heat recovery system whereby outside air is channeled through the exhaust air heat exchanger in order to withdraw the cold from outside air by means of the fluid in the exhaust air heat exchanger and channel it in particular by way of a heat exchanger into a cooling circuit.
