Example Embodiment

[0022] In order to facilitate the understanding of those skilled in the art, the concept of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Figure 1~4 The non-refrigerant air conditioning unit shown includes an indoor side and an outdoor side connected to the right side of the indoor side. The non-refrigerant air conditioning unit realizes multi-stage cooling and dehumidification through the combination of a surface cooler, a fan, and a wet curtain. It includes an outdoor side 21 that provides cooling water for the surface cooler, and an indoor side 20 that performs multi-stage processing on the air entering the room. The indoor side 20 and the outdoor side 21 are connected to form an integral non-refrigerant air conditioning unit.

[0024] A surface cooler 4 is installed in the indoor side, the surface cooler is installed in the middle of the indoor side, and an isenthalpic adiabatic...

Abstract

The invention relates to the technical field of refrigerant-free air conditioning units, in particular to a refrigerant-free air conditioning unit. A surface air cooler and a device for performing equal-enthalpy heat-insulation dehumidification treatment of the air cooled by the surface air cooler are arranged indoors. A cooling fan is arranged on an outdoor side wall, a first wet curtain component is arranged close to an air inlet which is formed on a side wall corresponding to the outdoor side wall on which the cooling fan is arranged, the first wet curtain is also connected with the surface air cooler arranged indoor through a first water supply component, and an evaporation cooling system consisting of the cooling fan, the first wet curtain component, the first water supply component (3) and the surface air cooler provides circulating cooling water for the surface air cooler. Outdoor fresh air is supplied by an indoor fan to the surface air cooler to be cooled and to the second wet curtain component to undergo equal-enthalpy heat-insulation dehumidification, and then enters rooms from an indoor air outlet. After the outdoor air is treated by the surface air cooler and the indoor wet curtain component, the temperature difference between indoor inlet air and outlet air reaches 8 to 15 DEG C, and thus, the cooling effect of a unit with a refrigerant system is achieved.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a non-refrigerant air conditioning unit that does not use a compressor and a refrigerant system but uses water to evaporate and cool. Background technique [0002] At present, the air conditioners sold in the market and widely used by users are basically air conditioners with compressors and refrigerant systems. The energy efficiency ratio of this type of compressor air-conditioning unit is about 3.0, and R22 refrigerant is widely used in China. Its ozone depletion index ODP is 0.05 and the greenhouse effect index is 0.34. In the future, R407C and R410A, which are substitutes for R22, have an ozone depletion index ODP of 0, but their greenhouse effect indexes are 0.36 and 0.42, respectively. They are also greenhouse gases, and their leakage will cause accelerated climate warming. It can be seen that any air conditioning system that uses refrigerant is not absolutely ...
