Abstract

The invention discloses a waste water afterheat drive type air conditioning fresh air system. The system comprises an air pipeline, a cooling water loop and an afterheat waste water pipe consisting of a fan, a first dehumidifying heat exchanger, a second dehumidifying heat exchanger, a humidity sensor, an evaporation cooler, a first circulating pump, a second circulating pump, a first electromagnetic valve, a second electromagnetic valve and the like. The system uses the dehumidifying heat exchangers for treating wet load of fresh air, uses evaporation cooling of one part of prepared dry air for preparing cooling water to burden the sensible heat load of the fresh air, realizes all-working-condition treatment of the fresh air, saves more energy compared with such traditional methods as refrigeration dehumidification, fully uses low-grade energy in traditional industrial life, is energy-saved and efficient, and is not limited by a regenerated heat source any more.

Description

technical field [0001] The invention relates to a wastewater waste heat-driven air-conditioning fresh air system and an operating method thereof, belonging to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for the comfort of work and life. At the same time, with the gradual depletion of fossil energy, energy problems have become increasingly prominent. This puts forward higher requirements for air conditioning system, which is a large energy consumer: more comfortable, higher air quality, and energy saving at the same time. In order to ensure the air quality of the building's air conditioning system, the fresh air system has become an indispensable part, and to a certain extent, the amount of fresh air is directly proportional to the indoor air quality, and is also proportional to t...
