Cool storage air conditioning device based on combination of evaporative cooling and water curtain outer wall

Abstract

The invention discloses a cool storage air conditioning device based on the combination of evaporative cooling and a water curtain outer wall. The device comprises an evaporative cooling air conditioner unit, a room tail end device, a reverse flow heat exchanger, a cool storage water groove and a water curtain outer wall module which are connected through a pipe network. According to the cool storage air conditioning device based on the combination of evaporative cooling and the water curtain outer wall, water in the water curtain outer wall in the daytime can flow in a circulating mode and take away solar radiant heat on the surface of a building, cooling load formed due to external envelope structure heat transmission is lowered, at night, a system can fully use advantages at night for carrying out cool storage, obtained low-temperature water is stored in an underground cool storage water groove and is used in the daytime, obtained cold air is used for cooling a room in a ventilation mode and cool storage, the time of cooling the room on the next day can be prolonged, and the device has the advantages that energy is saved, environment is protected, and economy is achieved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and relates to a cold-storage air-conditioning device combining evaporative cooling and a water-curtain-type outer wall. Background technique [0002] Many high-end buildings use glass curtain wall as the outer protective structure. In summer, when the sun shines on the curtain wall, part of the solar radiation is reflected, part of it directly enters the room through the glass curtain wall, and part of it is absorbed, and the absorbed part is converted into heat waves. The way of radiation to the indoor and outdoor respectively, which makes the cooling load in the building due to solar heat gain is very large, which in turn causes a large increase in air conditioning energy consumption. [0003] In addition, due to the high pressure on the urban power grid during the day, and the high electricity price during the day, the operating cost of the air-conditionin...

Problems solved by technology

[0004] Moreover, in hot weather in summer, after the air-conditioning system has finished operating for a day, the outdoor temperature is still high, and the heat is transmitted into the room through the enclosure structure, resulting in a large amount of residual heat in the room. When the air-conditioning system runs again the next day, it is necessary to increase the cooling capacity. To eliminate this part of waste heat, energy consumption increases
