Plant tin air conditioning of buildings

The invention relates to an air conditioning system of buildings with heat pumps arranged in different rooms, which can be switched to heating or cooling mode as required and their heat exchangers are switched on in a liquid circuit connected to a control center and a second, forced-ventilated heat exchanger for warming or cooling the room air, which is in the coolant circuit the heat pump is switched on.

Such systems are used in buildings where there is sunlight an evaluable temperature gradient between those on the sunny side and those on the shadow side Clearing occurs. As long as there is a sufficient temperature difference between the sunny and shady sides, will the heat released during the cooling of the sunny-side rooms is transported to the shady side via the liquid cycle unu used to heat the rooms stored there.

Such a heat recovery is only possible as long as at least some of the heat pumps are in cooling mode is working. As soon as heat is required in all rooms, the entire system must switch to electrical heating can be switched, whereby in the known systems the use of low tariffs due to a lack of saliva * possibilities is excluded.

The invention is based on the object of supplementing a system of the type described at the outset with little effort in such a way that that they switch off the heat pumps during the full heating periods, like conventional hot water heating systems be operated with a forced ventilation heat exchanger can.

According to the invention this object is achieved in that in a third fan assigned to the flow path of the second heat exchanger connected to the refrigerant circuit, is arranged parallel to the first heat exchanger connected in the liquid circuit heat exchangers, wherein the connections of the first and the third heat exchanger can be closed alternately by valves and that the The liquid circuit can be heated as required by an additional heater or cooled as required by an additional cooling system is.

It is possible in Hah ^^ n of the invention to use the auxiliary heating Train storage heating and for the Elina periods, in which also chilled the seams on the shady side, an * additional cooling to be provided.

The measures according to the invention make it possible to create a System for air conditioning of rooms optionally oOtinally in heat pump operation for heat recovery, to be used in conventional Eeir -: - operation or in entire Ililhlbetrieb, whereby through corresponding switching of individual units also intermediate stages possible s5.nd.
