Floor Radiant Air Conditioning System Based on Latent Heat Transfer Fluid

Abstract

The invention discloses a floor radiation air-conditioning system based on latent heat transfer fluid. The first medium is fluid, and the first medium is filled in the heat exchange tube; the second medium is filled outside the heat exchange tube, and the second medium exchanges heat with the external environment. ; The first medium includes the first phase-change material and the second phase-change material, the second medium includes the third phase-change material, the phase-change temperature range of the first phase-change material is denoted as [a, b], and the second phase-change material The phase transition temperature range of is denoted as [c,d], and the phase transition temperature range of the third phase transition material is denoted as [m,n], satisfying n≥d>a≥m. Beneficial effects: the third phase change material has good heat storage performance, can play a good buffering role on the indoor temperature, and is beneficial to reducing indoor temperature fluctuations and reducing overall energy consumption. The technical solution realizes the integration of refrigeration and heating by sharing heat exchange tubes, which is beneficial to saving space. The present invention relates to air conditioning systems.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a floor radiation air conditioning system. Background technique [0002] Air conditioning systems usually account for the largest proportion of a building's daily energy consumption. The floor radiant air conditioning system has greater comfort and energy saving advantages than the general air conditioning system. [0003] In the prior art, the common floor radiant air-conditioning system can only meet the heating requirements in winter, while in summer, other refrigeration delivery equipment is generally required to meet the cooling demand. The technical defects of the air conditioning system in the prior art are: the cooling and heating systems need to be set up separately, the economic cost is high and the building space is relatively large; in addition, the existing floor negative radiation air conditioning system is prone to condensation, There are technical problems such as h...
