Description

一种屋面喷淋与夜间蓄冷结合的蒸发冷却空调An evaporative cooling air conditioner combining roof spraying and night storage

技术领域technical field

本实用新型属于空调制冷设备技术领域,具体涉及一种屋面喷淋与夜间蓄冷结合的蒸发冷却空调。The utility model belongs to the technical field of air-conditioning and refrigeration equipment, in particular to an evaporative cooling air-conditioner combining roof spraying and night-time cold storage.

背景技术Background technique

目前,蒸发冷却空调的应用形式大多是采用蒸发冷却空调装置制备冷水或者冷风,同步向空调区供冷。在白天,干、湿球温度较高,机组的出风及出水温度也相对较高,此时机组的效率也相对较低;而在夜间,空气湿球温度相对较低,干、湿球温差较大,蒸发冷却空调机组的效率较高,而且制得的冷风、冷水温度较低。At present, most of the application forms of evaporative cooling air conditioners use evaporative cooling air conditioners to prepare cold water or cold air, and simultaneously supply cooling to the air conditioning area. During the day, the dry and wet bulb temperatures are high, and the unit’s outlet air and water temperatures are relatively high, and the efficiency of the unit is relatively low at this time; while at night, the air’s wet bulb temperature is relatively low, and the temperature difference between the dry and wet bulbs Larger, the efficiency of the evaporative cooling air conditioning unit is higher, and the temperature of the cold air and cold water produced is lower.

由于白天城市电网压力较大,而且白天电价较高,空调系统运行费用也就比较高,而夜晚电力处于低谷,电价也相对较低,由此想到如果利用晚间电力低谷时开启机组,将制得的冷量储存起来供白天使用,这样有利于缓解电网压力,节省运行费用。而且,夏季高温天气时,当空调系统结束一天运行后,室外温度依然很高,热量通过围护结构传入室内,使得室内余热量很大,第二天空调系统运行时,需要增加制冷量来消除这部分余热,能耗增加。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 conditioning system is also relatively high, while the electricity is at a low point at night, and the electricity price is relatively low. From this, it is thought that if the unit is turned on when the electricity is low at night, it will be produced. The cooling capacity is stored for daytime use, which is conducive to relieving the pressure on the power grid and saving operating costs. Moreover, in hot weather in summer, when 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 is running the next day, it is necessary to increase the cooling capacity. Removing this part of waste heat increases energy consumption.

将屋面喷淋降温与夜间蓄冷相结合而构成蒸发冷却空调,在白天通过屋面喷淋有效降低了通过屋顶传热形成的冷负荷;夜晚,该系统能够充分利用夜间有利的天气条件进行蓄冷,有效缓解白天的用电紧张,充分利用低谷电价制冷,降低运行成本;同时,晚上用蒸发冷却空调机组制取的冷风对房间通风降温蓄冷,从而延迟第二天向房间供冷的时间,具有节能、环保、经济的特点。The combination of roof spray cooling and night cold storage constitutes an evaporative cooling air conditioner, which effectively reduces the cooling load formed by roof heat transfer through roof spray during the day; at night, the system can make full use of favorable weather conditions at night for cold storage, effectively Alleviate the power shortage during the day, make full use of low-valley electricity prices for cooling, and reduce operating costs; at the same time, the cold air produced by the evaporative cooling air-conditioning unit is used to ventilate and cool the room at night, thereby delaying the time for cooling the room the next day, which has the advantages of energy saving, The characteristics of environmental protection and economy.
