Abstract

The invention discloses a solar assisted ground source heat pump cooling and heating system and a using method thereof. The system is mainly formed by connecting a solar heat collector, a solar heat storage water tank, a ground heat exchanger, a heat pump unit, a heat pump unit heat storage water tank and a user heat exchange device through a control circulation line. The using method of the solarassisted ground source heat pump cooling and heating system comprises the steps that the direct heat supply setting value of the solar heat storage water tank, the direct supply water temperature setting value, the water inlet temperature setting value of the heat pump unit and the anti-freezing temperature setting value of the solar heat storage water tank are set; a water temperature sensor T6of the solar heat storage water tank is used for obtaining the actual temperature value of water in the solar heat storage water tank, and the direct heat supply setting value of the solar heat storage water tank is compared with the actual temperature value of water in the solar heat storage water tank; and then a solenoid valve is used for controlling a corresponding circulation path, indoor heat supply is carried out, and the beneficial effects of being various in function, saving energy, being environment-friendly and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of building cooling, heating and heat storage. Background technique [0002] Currently, the heating and air-conditioning systems of office buildings and residential buildings consume a lot of energy. With the improvement of living standards, the power consumption and power generation also increase, and the peak-to-valley difference in power consumption is getting bigger and bigger. If the heating and air-conditioning system stores thermal energy during the low load period of the grid, and releases the stored thermal energy for heating during the peak period of electricity consumption, if the potential of solar energy and ground thermal energy storage and discharge is fully utilized, it can play a role in peak-shaving and valley-filling of the grid load , will contribute to energy saving and emission reduction, and produce good social and economic benefits. Contents of the invention [0003] The technical ...
