Problems solved by technology

But there is also a problem. When the ambient temperature is high in winter, the water supply temperature can be appropriately lowered. If the buried pipe method is used, the ground temperature may be lower than the recommended temperature value for human thermal comfort, resulting in a decrease in comfort.

Abstract

The invention discloses an energy-saving radiant cooling and heating heat pump system. The system comprises a cold and heat source component and a circulating water system, wherein the circulating water system comprises a water tank, the cold and the heat source component comprise a refrigerant-water heat exchanger, the refrigerant-water heat exchanger exchanges heat with the water tank, the watertank is connected with a ground buried pipe and a wall surface buried pipe, and the ground buried pipe and the wall surface buried pipe are connected through a switchable series-connection or parallel-connection pipeline; and series-parallel connection switching of the ground buried pipe and the wall surface buried pipe is achieved according to the switching temperature set by the system controller, meanwhile, the heat supply amount or the cold supply amount of the refrigerant-water heat exchanger is adjusted according to the outdoor environment temperature, energy conservation and environment protection are achieved, and meanwhile the comfort of people in an air-conditioned room is improved.

Description

technical field [0001] The invention relates to a radiant cooling and heating heat pump system and a control method, and relates to the technical field of heat pump / refrigeration and energy saving. Background technique [0002] Due to the high energy efficiency of the heat pump system and the good thermal comfort of radiant heating, the application of the heat pump hot water radiant heating system is increasing. With the improvement of people's living standards, people are more and more concerned about the thermal comfort of cooling in summer, so radiant cooling with good thermal comfort has attracted more and more attention. A kind of radiant cooling and heating heat pump system that realizes radiant cooling in summer and radiant heating in winter has begun to have some application cases and is developing rapidly. The main technical problems faced in the development of this technology are to make the thermal comfort better and the system operation more efficient and energy...
