Vacuum sorption device e.g. for heating source created as burner, has heat source with two heat exchangers and heat distribution medium is filled with refrigerant and heat exchangers are connected to heat distribution medium cycle

摘要

The vacuum sorption device has heat source (8) with two heat exchangers (1, 2). A heat distribution medium is filled with a refrigerant. The heat exchangers are connected to a heat distribution medium cycle (5) and a removal connection (10) is provided by bypassing and uncoupling from the heat distribution medium cycle. At the removal connection (10), a hydraulic branching (11, 12) is provided where the supply connection (9) has a pump provided between the supply-connection-lateral branching (11) and the heat exchanger (1) Additionally, at the removal connection between the drive off-connection-lateral branching (12) and the heat exchanger (1) a closing check valve (14) is provided. A second closing check valve (15) is provided at the supply connection, where the first check valve (14) has an opening pressure larger compared to the pressure loss over a bypass (7). The heat distribution medium cycle is designed as a heating cycle at the same time.
