High-energy-efficiency-ratio heat pump system and control method thereof

Abstract

The invention discloses a high-energy-efficiency-ratio heat pump system. Main loop input circulation pipelines, a main loop power driving circulation pump, soft connection parts on the front side and the rear side of the pump body and a Y-shaped dirt remover form a self-closing input circulation loop of the system body through main loop manual butterfly valves of the system. The heat pump system further comprises a power source analog heating medium and refrigerant convey-out device, the power source analog heating medium and refrigerant convey-out device is connected with main pipelines on the front side and the rear side of the main loop power driving circulation pump in the self-closing input circulation loop of the system body through a manual gate valve, the Y-shaped dirt remover, the small-power circulation pump and an electric gate valve, and the main pipeline on the rear side of the main loop power driving circulation pump is communicated with the water return end of the power source analog heating medium and refrigerant convey-out device through a one-way check valve and the manual gate valve. The high-energy-efficiency-ratio heat pump system has the advantages that the energy efficiency ratio in operation of the heat pump system can be effectively increased, the work condition output effect level can be effectively improved, the investment cost of the facility can be reduced, the occupied area of a site is saved, and popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to a heat pump system with high energy efficiency ratio and a control method thereof. Background technique [0002] Over the years, in the development of heat pump series products and system application technology, attention has generally been paid to changes in the structure and shape of the heat pump itself, especially in terms of energy saving and consumption reduction during use, and the improvement of the energy efficiency ratio of heat pumps. Almost reached the extreme, the energy efficiency ratio of the air source heat pump is about 1:3.2, and the energy efficiency ratio of the ground source heat pump is about 1:4. In addition, the application of ground source heat pump system technology has certain environmental adaptability compared with the air source heat pump system in the area north of the Yangtze River in my country. Big problems, especially similar to t...
