Double-terminal air source heat pump system with phase change heat storage material floor heating module

Abstract

The invention discloses a double-end air source heat pump system with a floor heating module made of a phase change heat storage material, comprising air conditioning equipment and a floor radiant heating end device. The floor radiant heating end device comprises a moisture-proof layer, a heat insulation material layer, a floor heating module, and an aluminum foil layer. The slots of support templates are filled with a phase change heat storage material. The upper surface of the phase change heat storage material and the aluminum foil layer are each provided with a downward arc sag at a groove, a heat supply branch pipe is laid in each arc sag, and the two ends of each branch heat supply pipe are respectively connected with a main heat supply pipe and a main heat recovery pipe through a distributor. The air conditioning equipment and the floor radiant heating end device are connected by a branch pipe. Adjusting control valves are arranged between connecting pipelines of the devices, and the connecting pipelines are filled with refrigerant. The energy efficiency ratio of air source heat pumps is improved. The problem of defrosting is solved while indoor thermal comfort is satisfied. Modular production and on-site splicing installation are achieved, and the construction difficulty is lowered.

Description

technical field [0001] The invention relates to an air source heat pump air-conditioning system device, in particular to an aluminum foil heat conduction, floor heating module, phase change heat storage, direct condensation type floor heating terminal device and cooling terminal device. Background technique [0002] With the development of social and economic level, people's requirements for indoor environment continue to increase, and building energy consumption continues to increase. From 1996 to 2013, the building area increased rapidly, and the total building energy consumption has reached more than 28% of my country's total energy consumption. Among them, the energy consumption of air conditioning and heating can exceed 50% of the total energy consumption of the building, so reducing the energy consumption of air conditioning and heating has become one of the key issues of building energy conservation and emission reduction. In recent years, air source heat pumps have ...

AI Technical Summary

Problems solved by technology

Electric heating assistance is a common defrosting method for air source heat pumps, but this method changes high-grade energy into low-grade energy during the application process, resulting in downgraded energy utilization and reduced system energy efficiency
