Solar photovoltaic water pump heating and refrigerating system and use method thereof

Abstract

The invention discloses a solar photovoltaic water pump heating and refrigerating system and a use method of the solar photovoltaic water pump heating and refrigerating system. The system comprises a photovoltaic array, a photovoltaic charging controller, an inverter, a water pump, an underground water storage pool, a cold water storage tank and a hot water storage 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 main board through wires. The control main board is connected with the water pump and a semiconductor refrigerating host through wires. The solar photovoltaic water pump heating and refrigerating system has the advantages that indoor constant temperature is maintained in various operation modes, solar generated power is used as the main part, municipal power is used as the auxiliary part, energy is saved, the operation mode that a semiconductor refrigerating device heating water cycle is adopted as the main part and solar collected heat is adopted as the auxiliary part is adopted, domestic hot water heating is guaranteed, semiconductor heating and refrigerating operation is free of noise, operation efficiency is high, and indoor temperature is adjusted.

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 for home heating: use natural gas for heating, which is expensive to use and cannot be used for cooling; use air-conditioning for heating or cooling, and the electricity bill is very expensive, and the air is dry after use, which makes people feel uncomfortable; in the north, it is directly used. Coal heaters are fired to heat, coal will produce air pollution, and there are carbon monoxide, which poses a safety hazard. Natural gas is used for heating, and natural gas will produce carbon dioxide, which will aggravate the greenhouse effect, and the high price of natural gas will increase the economic burden. Contents of the invention [0003] The purpose of the present invention is to provide a solar p...
