Arrangement for a cold-heat coupling

The invention relates to an arrangement for a cold-heat coupling with a refrigerant circuit and with a heat pump cycle, which have a common vaporizer-condenser or a common intermediate pressure tank and are thereby connected thermally to each other, wherein the refrigerant circuit further comprises at least an evaporator, a refrigerant compressor and a throttle valve, and the heat pump cycle also have at least one heat pump compressor, a liquefying and a WP-throttle valve, the intermediate pressure tank has in its bottom portion a sump region in which liquid refrigerant is disposed WP-throttle valve downstream of the condenser, the evaporator-condenser separate channels are present, which are on the one hand to the cold water circuit and on the other hand to the heat pump cycle and having the wall portions of the channels of the evaporator-condenser heat transfer surfaces on the one hand to the cold circuit and on the other hand adjacent to the heat pump cycle. According to the invention in the refrigerant circuit, in addition to above mentioned components, at least one controllable heat exchanger, a heat radiator, disposed downstream of the refrigerant compressor, and it is in the heat pump cycle in addition to the components listed above, at least one controllable heat exchanger, an auxiliary evaporator outlet and inlet, an auxiliary evaporator with outlet and inlet or an additional evaporator outlet and inlet, arranged which is communicatively connected to the intermediate-pressure tank, or it is a flow connection exists downstream of the liquefying with an auxiliary throttle valve, which opens into the auxiliary evaporator, wherein the heat-radiator between the drain and feed is connected to an external heat sink and the auxiliary evaporator between outlet and inlet with an external heat source.
