Abstract

The invention discloses a solar-assisted heat pump combined heating and refrigerating system and method. The system comprises a solar heat collection station, a double-source heat pump unit and an indoor heating and refrigerating tail end, wherein the solar heat collection station comprises a solar heat collector and a heat-accumulation water tank, the heat-accumulation water tank is connected with a heat collection circulation pump and the solar heat collector through pipelines sequentially, and one pipeline returns to the heat-accumulation water tank from the solar heat collector; and the double-source heat pump unit comprises an air source heat pump unit and a water source heat pump unit, a water inlet, a water outlet, an air-condition vent and an air-condition return port are formed in the double-source heat pump unit, the water inlet is sequentially connected with a heat pump circulation pump and the heat-accumulation water tank through pipelines, the water outlet is connected with the heat-accumulation water tank through a pipeline, and the air-condition vent and the air-condition return port are connected with the indoor heating and refrigerating tail end. The system can effectively utilize solar energy, water energy and air energy and can perform conversion among the three types of energy supply according to the water temperature change, so that energy is sufficiently and reasonably utilized, and the resource waste is reduced.

Description

technical field [0001] The present invention relates to a heating and cooling system, and more specifically, to a solar heat pump combined heating and cooling system and method. Background technique [0002] Existing heating and cooling systems usually only use energy from solar, water or air sources. When these types of energy are used for heating and cooling, it is easy to waste energy, and it is impossible to switch between heating modes according to the actual temperature. Using the existing heating and cooling system not only cannot replace the corresponding heating mode according to the actual water temperature, resulting in energy waste, but also cannot guarantee the timeliness and stability of heating. For example, when using solar energy as energy for heating, if it is rainy, solar energy cannot be utilized so, and the heating effect cannot be reached. If only water or air is used for heating, the required temperature may not be reached, and a lot of resources are...
