Problems solved by technology

[0005] The purpose of this disclosure is to provide a capillary tube radiant heating system based on refrigerant two-phase flow heat exchange, which can solve the problem that the existing air source heat pump uses a fan to blow air at the end of the room, which is easy to generate noise, and the air source heat pump is used with low temperature water for floor radiant heating. It is necessary to equip heat exchangers to realize low-temperature water intermediate heat exchange, etc., and reduce the noise caused by fans while improving the heating efficiency of air source heat pumps

Abstract

The invention relates to a refrigerant two-phase flow heat exchange based capillary tube radiant heating system. The refrigerant two-phase flow heat exchange based capillary tube radiant heating system comprises a heat pump main engine and a capillary network, wherein the heat pump main engine and the capillary network define a circulating loop; a refrigerant is circulated in the circulating loop;the heat pump main engine can heat the refrigerant to a superheated steam state, and can fed in the refrigerant from an inlet of the capillary network; the refrigerant can perform heat exchange withthe side wall of the capillary network, so that radiant heating, on outer environment, of the capillary network is realized; after the refrigerant in the superheated steam state releases part of heat,part of the refrigerant is condensed to form a gas-liquid two-phase flow state; and the refrigerant in the gas-liquid two-phase flow state can keep the temperature unchanged in a flowing process, sothat the capillary network provides constant-temperature heating. The refrigerant two-phase flow heat exchange based capillary tube radiant heating system can solve the problems that noises are liableto generate and the like as the indoor tail end of an existing air source heat pump adopts an air blower to blow air.

Description

technical field [0001] The disclosure belongs to the technical field of heat pump radiation heating, and in particular relates to a capillary radiation heating system based on refrigerant two-phase flow heat exchange. Background technique [0002] Air pollution and smoggy weather caused by coal-fired central heating in winter have received a lot of attention. Central heating with electric-driven heat pump units with high energy efficiency has become an important measure to solve the problem of heating residents in winter and solving pollution. The coal-to-electricity technology currently implemented in my country mainly uses air-cooled heat pumps to solve the heating problem in winter, and has been vigorously promoted in various regions. At present, the indoor terminal of small household air source heat pumps can be wall-mounted or floor-mounted, and the indoor fan blows hot air to supply heat to the room. The indoor thermal comfort is relatively poor, and the fan brings no...
