Abstract

The invention discloses a solar PVT thermoelectricity co-supplying system driven by a refrigerant pump. The solar PVT thermoelectricity co-supplying system driven by the refrigerant pump comprises an electrical power system and a refrigerant mechanical circulation solar heat pump system, and the electrical power system and the refrigerant mechanical circulation solar heat pump system are relativelyindependent; the refrigerant mechanical circulation solar heat pump system comprises a water subsystem and a refrigerant subsystem; a circulating water pump is adopted as power drive for the water subsystem, and the water subsystem comprises a heat storage water tank, the circulating water pump and a plate type heat exchanger. The refrigerant subsystem is driven by a refrigerant pump, and comprises an efficient solar thermoelectricity co-generation component, a plate type heat exchanger, the refrigerant pump, and a liquid storage tank, the refrigerant pump sends liquid refrigerant in the liquid storage tank into a heat exchanging tube flow channel of the efficient solar thermoelectricity co-generation component, refrigerant vapor in the heat exchanging tube flow channel enters the plate type heat exchanger, and conducts heat exchanging with water in the plate type heat exchanger, when the refrigerant vapor is condensed into liquid, heat is released at the same time, and then the condensate refrigerant is converged into the liquid storage tank. The electrical power system is designed into a grid combining power generation system, a mains supply complementary off-grid power generation system and an energy storage and microgrid system, and the grid combining power generation system, the mains supply complementary off-grid power generation system and the energy storage and microgrid system are synergetically and cooperatively used and flexibly transformed and switched.

Description

technical field [0001] The invention relates to a novel refrigerant mechanical circulation solar heat pump system driven by a refrigerant pump, which can synchronously and efficiently develop and utilize solar energy resources and a solar PVT combined heat and power system. Background technique [0002] Solar collectors have been widely used in energy power, refrigeration and air conditioning, social life, aerospace technology and other fields, but there are many problems in the utilization of solar energy. The low utilization rate of solar energy is the bottleneck of solar energy utilization at present. The solar cogeneration system, which can significantly improve the comprehensive utilization efficiency of solar energy in the process of solar photovoltaic power generation, solve the cooling problem of photovoltaic cells, and realize the simultaneous and deep development and utilization of solar photovoltaic / photothermal resources, has begun to show its performance advanta...
