Abstract

The invention discloses a floor radiation air-conditioning system based on latent heat thermal fluid, and relates to an air-conditioning system. A first medium is fluid, and the first medium fills theinner of a heat exchanger tube; a second medium fills the outer of the heat exchanger tube, and the second medium exchanges heat with the external environment; the first medium includes a first phase-change material and a second phase-change material; the second medium includes a third phase-change material; and the phase-change temperature range of the first phase-change material is marked as [a, b], the phase-change temperature range of the second phase-change material is marked as [c, d], the phase-change temperature range of the third phase-change material is marked as [m, n], and the condition that n is greater than or equal to d, d is greater than a, and a is greater than or equal to m is met. The beneficial effects are that the third phase-change material has good thermal storage performance and can play a good buffer role on indoor temperature, so that the reducing of the indoor temperature fluctuation and the overall energy consumption is facilitated; and according to the technical scheme, the integration of refrigeration and heating is achieved by sharing the heat exchange tube, so that the space-saving is facilitated.

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...
