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.

What is claimed is: 1. A heat recovery system comprising: at least one exhaust air heat exchanger, mounted in the exhaust air stream of a ventilation and/or air conditioning plant, and at least one outside air heat exchanger mounted in the intake air stream of the ventilation and/or air conditionin
What is claimed is: 1. A heat recovery system comprising: at least one exhaust air heat exchanger, mounted in the exhaust air stream of a ventilation and/or air conditioning plant, and at least one outside air heat exchanger mounted in the intake air stream of the ventilation and/or air conditioning plant, whereby the at least one exhaust air heat exchanger and the at least one outside air heat exchanger constitute an integrated circuit configured to recover heat from the exhaust air, wherein there is at least one partial circuit separated from the integrated circuit configured to extract cold from the outside air during nighttime in which is mounted the at least one exhaust air heat exchanger, and wherein outside air cooled in an evaporator device for adiabatic cooling is channeled through the at least one exhaust air heat exchanger in order to cool a fluid in the partial circuit, whereby the partial circuit features at least one heat exchanger to transfer cold from the fluid in the partial circuit into a cooling circuit having a cold storage withdraw a cooled fluid during daytime. 2. The heat recovery system according to claim 1, wherein the integrated circuit is separated into at least two partial circuits, whereby the exhaust air heat exchanger is mounted in a first partial circuit and the outside air heat exchanger is mounted in a second partial circuit, and whereby the outside air is traversed by outside air for direct channeling of outside air into the ventilation and/or air conditioning plant, and whereby the exhaust air heat exchanger is traversed by outside air for the recovery of cold from the outside air. 3. The heat recovery system according to claim 2 wherein the pumping output required for the operation of heat recovery in the integrated circuit is subdivided over at least two pumps, one of which is mounted in each of the at least two partial circuits. 4. The heat recovery system according to claim 2 wherein a device for warming up the fluid is mounted in the second partial circuit of the outside air heat exchanger, in order to provide heating for the incoming outside air in the outside air heat exchanger. 5. The heat recovery system according to claim 1 further comprising a blower that is mounted downstream of the exhaust air heat exchanger, by which the outside air is suctioned in, whereby the entire outside air suctioned in is divisible into one first partial flow leading through the outside air heat exchanger into the ventilation and/or air conditioning plant, and a second partial flow leading through the exhaust air heat exchanger outward, whereby in particular the ratio of the subdivision of the outside air flow into the first and second partial flows can be adjusted. 6. The heat recovery system according to claim 5 wherein the first partial flow channeled through the ventilation and/or air conditioning plant, is channeled through a bypass on the exhaust air heat exchanger. 7. The heat recovery system according to claim 1 wherein upstream of the exhaust air heat exchanger there is mounted a blower which conveys the entire air flow in the heat recovery operation and which conveys in the cooling operation the entire outside air flow used to directly cool the building, whereby a separate blower is subordinated to the exhaust air heat exchanger which blower handles only the outside air flow to produce cold, so that the air flow volumes from the at least one outside air heat exchanger and the at least one exhaust air heat exchanger are independently adjustable. 8. The system of claim 1, wherein the at least one partial circuit is switchably separable from the integrated circuit and is configured to extract cold from the outside air during nighttime when switched into a separated condition. 9. A method for recovery of nighttime cold from outside air with the aid of an integrated circuit heat recovery system comprising: channeling outside air over an evaporator device for adiabatic cooling and through an exhaust air heat exchanger in order to withdraw cold out of the outside air by means of a fluid in the exhaust air heat exchanger, wherein the integrated circuit is subdivided into two self-sufficient partial circuits, whereby the recovery of nighttime cold occurs by way of one partial circuit and channeling the cold by way of a second heat exchanger arranged in this partial circuit into a cooling circuit having a cold storage unit and storing the cold in the cold storage unit and withdrawing the cold stored in the cold storage unit during daytime as needed, and whereby the other partial circuit provides minimum temperature controlled or regulated nighttime-cold cooling by way of the outside air heat exchanger. 10. The method of claim 9 further comprising storing heat in the heat/cold storage unit, withdrawing stored heat from the heat storage as needed to warm up the outside air channeled in through the outside air heat exchanger in order to attain a minimum required temperature of the incoming air.
