Air-conditioning method with function of passive cooling of indoor air through water circulation and device

Abstract

The invention provides an air-conditioning method with the function of passive cooling of indoor air through water circulation and a device. The method is carried out as follows: the air beyond the air-conditioning zone is sent to the air-conditioning zone after being handled by an air handling unit, the exhaust air in the air-conditioning zone is exhausted out of the air-conditioning zone after passing through an evaporative cooling device in the air-conditioning zone, the cold water sent out from the cold water end of the evaporative cooling device is returned to the evaporative cooling device by the return water end of the evaporative cooling device after passing through a water heat absorption device of a passive cooling integrated device. The invention can be applied to various air-conditioning systems and substantially absorb the heat gain of solar radiation of the light-transmitting enclosure structure by way of passive cooling while regulating the air in the air-conditioning zone by way of active cooling, thus effectively reducing the load of the indoor air-conditioner, lowering the supplied air volume, reducing the overall dimension of the unit and the sectional area of the air pipe and being easy to match with the building space and lower in cost. The invention is especially applied to the dry air energy evaporative cooling air-conditioning systems and is especially suitable for air regulating of the rooms in various residences, public buildings, etc.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilating and air-conditioning, and relates to an air-conditioning method with internal air-water circulation passive cooling and its device, which is suitable for air conditioning in various types of residential buildings, public buildings and industrial buildings, especially in dry and hot areas. Applications in various buildings. technical background [0002] The "Design Standards for Energy Conservation of Public Buildings" promulgated and implemented by China in 2005 pointed out that China's building energy consumption has exceeded 1 / 4 of the country's total energy consumption, and will gradually increase to more than 1 / 3 with the improvement of people's living standards. In building energy consumption, HVAC energy consumption accounts for about 27.4%. Therefore, vigorously advocating HVAC energy conservation plays a vital role in building a resource-saving, environment-friendly, low-carbo...

AI Technical Summary

Problems solved by technology

[0025] The invention provides an air-conditioning method and its device with internal air-water circulation passive cooling, which overcomes the deficiencies of the prior art and effectively solves the air-conditioning problems caused by the high heat gain of solar radiation due to light-transmitting enclosure structures such as windows. The problem of high energy consumption, it can not only effectively adjust the air condition in the air-conditioning area, but also greatly reduce the load of light-transmitting enclosure structures such as windows, and the cost is low, and it is easy to cooperate with buildings
