SOLAR HEAT PUMP HEATING SYSTEM WITH SELF-DRIVING SEPARATED HEAT PIPE ENERGY STORAGE DEVICE, AND CONTROL METHOD THEREFOR

摘要

A solar heat pump heating system with a self-driving separated heat pipe energy storage device, and a control method therefor. A solar heat collection evaporator array (1) is connected to a back temperature control unit (2). The back temperature control unit (2) is connected to a self-driving unit (3) and a host unit (4). The self-driving unit (3) is connected to the host unit (4) and an energy storage unit (5). The energy storage unit (5) is further connected to the host unit (4). The host unit (4) is further connected to a tail end heat exchange unit (6). A heat pump, the solar thermal application technology and the self-driving separated heat pipe energy storage technology are combined, solar energy is used as a low-temperature heat source, and the energy storage device is used for storing redundant solar energy and providing the low-temperature heat source, so the operation efficiency and the solar energy utilization rate of the heat pump system are improved; a solar heat collection evaporator refrigerant evacuator, a compressor back temperature control device and a refrigerant flow rate control device for multiple solar heat collection evaporators connected in parallel are additionally arranged, so the complex and variable working conditions of the solar heat pump are met, and productization of the solar heat pump heating technology is achieved.
