Central air-conditioning environmental-protection energy-saving cyclic utilization system

Abstract

The invention discloses a central air-conditioning environmental-protection energy-saving cyclic utilization system. A surface cooler and a plate exchanger are respectively installed on an air-conditioning fresh air port, a main air return pipe and a box body air return port. And therefore, mould pressure is reduced, temperature in a coating plant is reduced, working performance of equipment is stabilized, product quality and production efficiency are improved, simultaneously energy is saved, hot water produced by recycling waste heat of an air-conditioning set is supplied to staff dormitories and canteens for use, and a lot of energy is saved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning environmental protection and energy saving, in particular to a central air-conditioning environmental protection energy-saving recycling system. Background technique [0002] Central air conditioners are installed in the molding and coating workshops to achieve the purpose of purifying the air and sending in fresh air and cold air. It is directly sent to the workshop, the highest temperature at noon reaches 36°C, and the circulating air volume reaches 38000M3 / H. The 14 5P cabinet air conditioners in the workshop alone are still unable to cool, and only some spaces have air conditioning. In summer, the high-temperature workshop temperature reaches 43°C, which affects the products. Quality stability reduces production efficiency; and the air conditioner works continuously for 24 hours, and the daily electricity consumption is: 52.5 degrees * 24 = 1260 degrees, and the monthly (26 days) powe...

[0002] Central air conditioners are installed in the molding and coating workshops to achieve the purpose of purifying the air and sending in fresh air and cold air. It is directly sent to the workshop, the highest temperature at noon reaches 36°C, and the circulating air volume reaches 38000M3 / H. The 14 5P cabinet air conditioners in the workshop alone are still unable to cool, and only some spaces have air conditioning. In summer, the high-temperature workshop temperature reaches 43°C, which affects the products. Quality stability reduces production efficiency; and the air conditioner works continuously for 24 hours, and the daily electricity consumption is: 52.5 degrees * 24 = 1260 degrees, and the monthly (26 days) power consumption is 32760 degrees * 0.5 yuan / degree = 16380 yuan; In addition, There are serious safety hazards in the old-fashioned liquefied gas water heaters used for hot water in the staff buildings, and the water supply pressure is low and unstable, which makes it extremely inconvenient for staff to use water
