Evaporative refrigeration method based on external sunshading cooling and plant

Abstract

The invention relates to an evaporative refrigeration method based on an external sunshading cooling and a plant thereof. The plant comprises an evaporative refrigeration device, an indoor area and an external sunshading passive evaporative cooling integration device, wherein the evaporative refrigerating plant comprises at least one air intake and not less than one air outlet; the external sunshading passive evaporative cooling integration device comprises an external sunshading installation and a translucency containment structure; and not less than one layer of airflow channel formed by the sunshading installation self or between the external sunshading installation and the translucency containment structure is an air exhaust cavity. The invention has the following effects: the heat gain of the room is effectively reduced in summer, the invention is more easy to match in construction and has low cost, is more reasonable and sufficient in the utilization of energy, constructs the channel for indoor and outdoor contact, effectively solves the problem of disorderly air exhausting in an air-condition system, enables the indoor and outdoor air flow to be more smooth, lays a reality basis for the application in large scale of the evaporative refrigeration air conditioning technology in housing construction and other civil architectures, and widens the area suitable for the evaporative refrigeration air conditioners.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilation and air conditioning, and is an evaporative cooling method and device based on external shading and cooling. It is suitable for air conditioning in various residential buildings, public buildings, industrial buildings and other rooms, or is a method for cooling non-air-conditioned rooms. Device. technical background [0002] The "Energy-saving Design Standards for Public Buildings" promulgated and implemented in 2005 pointed out: my country’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, the energy consumption of HVAC accounted for about 27.4%. Therefore, vigorously advocating energy-saving HVAC plays a vital role in building a resource-saving and environment-friendly low-carbon society. [0003] The cooling load borne by a...
