Residential radiating plane air-conditioning flow distribution regulating system

Abstract

The invention relates to a residential radiating plane air-conditioning flow distribution regulating system which consists of a refrigerating and heating host module (1), a flow distribution regulating module (2), a radiating end heat exchanger module (3), and pipelines and an auxiliary assembly; a typical system comprises a host machine of a cold and heat source unit, a water-cooling evaporator, a first-level flow distribution collector, a second-level flow distribution collector, a first-level radiating end heat exchanger and a circulating pipeline and general accessories, wherein the first-level flow distribution collector is configured with the host machine together, the second-level flow distribution collector is arranged in a proper wall hole of each air-conditioning heat pump room, a capillary tube net boom radiating end and a novel radiating end heat exchanger are both pre-arranged on a floor, the inner surface of a wall or a ceiling of a room needed to be refrigerated and heated, so as to avoid hydraulic misadjustment owning to more loops and large difference of all loop resistances, ensure the water flow balance of the system and enhance the heat-exchange effect of the heat exchanger; the residential radiating plane air-conditioning flow distribution regulating system is simple in structure and is reliable in operation.

Description

technical field [0001] The present invention relates to a flow distribution adjustment system for a comfortable household-type radiant plane air conditioner, in particular to a multi-level series-parallel flow distribution for a comfortable household-type radiant plane air-conditioner radiation end heat exchanger device Collection and conditioning system. Background technique [0002] In recent years, radiation has been used as a new type of air conditioner to control sensible heat [the sensible heat load (cooling) of the air conditioner accounts for about 50% to 70% of the total load, and the latent heat load (humidity removal) accounts for about 30% to 50% of the total load] The method has been applied to a certain extent, and has advantages that cannot be compared with traditional air conditioning methods; the cold fluid (or hot fluid) transfers energy to the surface of the radiant panel through the radiant panel for convection and radiation, and directly communicates wit...

AI Technical Summary

Problems solved by technology

For medium and large radiant refrigeration heat pump systems, due to too many heat exchanger loops at the radiant end and the large difference in resistance of each loop, it is easy to cause hydraulic imbalance, resulting in poor heat exchange effect at some radiant ends

On the other hand, the loop forms of fluid flow in the heat exchanger at the radiant end include series, parallel, and mixed connections, and the flow state is mainly turbulent flow. The series method generally requires a larger diameter water supply pipe for the radiant end heat exchanger. The accumulated air is easy to discharge, but the pipeline system should not be too long, otherwise the system resistance loss will be too large, and the radiation heat exchanger at the end of the system will not be able to effectively play the role of radiation heat exchange; the parallel connection method is generally used for smaller branch pipe diameters The radiant end heat exchanger has high heat exchange efficiency, but care must be taken in the design and installation to ensure that the fluid flow rate in the pipe is high to fully discharge the air. The inlet and outlet of a parallel circuit have the same pressure
