Multi-heat-source indirect PVT (Pressure-Volume-Temperature) heat pump system suitable for buildings and running method thereof

Abstract

The invention relates to a multi-heat-source indirect PVT (Pressure-Volume-Temperature) heat pump system suitable for buildings. The multi-heat-source indirect PVT heat pump system comprises a power grid, an inverter, a PVT heat collector tile, a heat-exchanging pipeline, a roof or inclined surface, an electromagnetic three-way valve A, a heat collector water box, a phase-change heat-storage device, a heat pump evaporator, a circulating water pump, an electromagnetic three-way valve B, an air-cooled heat exchanger A, an electromagnetic three-way valve C, a compressor, an air-cooled heat exchanger B, an electromagnetic three-way valve D, a domestic water tank, a water-cooled condenser, a pipeline A, a water-water heat exchanger, a pipeline B, an electromagnetic three-way valve E, an expansion valve, an electromagnetic three-way valve F, a tile convex part, a photovoltaic module, a flat plate heat pipe, a heat-insulating material, heat-conducting glue, a tile plane part, a tile, phase-change microcapsules, a metal net box, a phase-change material and a shell. The multi-heat-source indirect PVT heat pump system has the beneficial effects that mounting and maintenance are facilitated;true building integration is realized under the condition of not damaging the functions of keeping out wind and rain and insulating heat of the conventional tile; and the application prospect of a PVTtechnology is expanded.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and in particular relates to a multi-heat source indirect PVT heat pump system suitable for buildings and an operation method thereof, which can effectively reduce building energy consumption. Background technique [0002] Building energy consumption accounts for nearly 1 / 3 of my country's total social terminal energy consumption, and this proportion will continue to increase with the improvement of economic level, of which heat and electricity consumption account for the vast majority of building energy consumption. my country is rich in solar energy resources, and the use of solar energy can effectively alleviate the demand in this area. Common solar energy utilization methods in daily life are solar water heaters and photovoltaic power generation, but these technologies require a large installation area to meet the power and heat supply required by users, which has certain limitations f...

Problems solved by technology

There are two problems in the indirect system currently proposed. One is that the coupling method with the building is relatively simple, which limits the popularization and application in the building. increase, the cooling effect of photovoltaic modules decreases, and the system performance decreases
