Solar heating and refrigerating integrated system and utilization method thereof

Abstract

The invention discloses a solar heating and refrigerating integrated system and a utilization method thereof. The system comprises a photovoltaic array, a photovoltaic charging controller, an inverter, a water pump, an underground reservoir, a cold water tank and a hot water tank. The photovoltaic array is connected with the photovoltaic charging controller through a wire, the photovoltaic charging controller is connected with a switch box through a wire, the switch box is connected with a storage battery, the inverter and a control mainboard through wires, and the control mainboard is connected with the water pump and a semiconductor refrigerating mainframe through wires. The solar heating and refrigerating integrated system and the utilization method thereof have the advantages that indoor normal temperature can be guaranteed by means of various operating modes; since solar power generation is assisted by the mains supply, energy is saved; by adoption of an operating mode that the semiconductor refrigerator for heating and water circulation is assisted by an air source, household hot water supply and heating can be guaranteed, noise in semiconductor heating and refrigerating operation is avoided, and high operating efficiency and adjustability of indoor temperature are realized.

Description

technical field [0001] The present invention relates to a solar heating and cooling system, and more specifically, to a solar photovoltaic water pump heating and cooling system and its application method. Background technique [0002] At present, there are several methods of home heating: heating with natural gas, which is expensive to use and cannot be used for cooling; heating or cooling with air conditioning, the electricity bill is very expensive, and the air is dry after use, and auxiliary equipment such as an air humidifier is required; Direct use of solar energy for heating has low heating efficiency, and there is seasonality in use, and direct use of solar energy is unstable. Solar energy can save a lot of non-renewable energy, but it needs to cooperate with other auxiliary equipment. Contents of the invention [0003] The purpose of the present invention is to provide a combined solar energy heating and cooling system and its application method which can save ...
