Problems solved by technology

But on the other hand, chilled water or direct evaporation dehumidification methods are currently used for air treatment. The increase in fresh air volume greatly increases the energy consumption of fresh air treatment, and the air outlet temperature is lower than the room dew point temperature, and the air outlet is prone to condensation. , and when the airflow organization design is not good, it will cause discomfort to the human body; the existence of condensed water forms a hotbed for various molds on the surface of the coil, which deteriorates the indoor air quality and causes a variety of sick building syndromes

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] see figure 1 , figure 2 , The energy-saving low-humidity fresh air air conditioner is composed of a fan (8), an air-to-air total heat exchanger (1), a surface heat exchanger (2) and a plurality of air valves. Surface A and surface D of the air-to-air total heat exchanger are located between the fresh air inlet and the fan (8) and are separated by partitions, and surfaces A and D of the air-to-air total heat exchanger are respectively equipped with air valves (5 ) and air valve (6); the fresh air passes through the air-to-air total heat exchanger (1) and then passes through the surface heat exchanger (2), between the air inlet side of the surface heat exchanger (2) and the fan (8) Separated by a partition, the partition is equipped with a damper (4), between the air outlet side of the surface heat exchanger () 2 and the fresh air inlet is separ...

Abstract

The invention provides an energy-saving and low-humidity fresh air conditioner and belongs to the field of energy utilization techniques and air conditioning. The air conditioner comprises a fan, an air-air total heat exchanger, a surface-type heat exchanger and air valves. Low-temperature cold water surface-type heat exchanger and the air-air total heat exchanger are used for performing dew point dehumidification and heating dehumidification on fresh air in summer; the air valves are switched in winter, and the hot water surface-type heat exchanger is used for heating fresh air. The air-air total heat exchanger is used for performing total heat exchange and heating dehumidification on fresh air in different stages.

Description

technical field [0001] The invention relates to a dehumidifying fresh air air conditioner, in particular to an energy-saving low-humidity fresh air air conditioner. Background technique [0002] Most of the air-conditioning systems in civil buildings in my country adopt the mixed mode of fresh return air. Since most of the air circulates indoors, pollutants cannot be discharged outdoors quickly, which is harmful to human health. Increasing the fresh air volume (or adopting fresh air operation mode) can dilute indoor harmful substances and discharge them outdoors, significantly improving indoor air quality. But on the other hand, chilled water or direct evaporation dehumidification methods are currently used for air treatment. The increase in fresh air volume greatly increases the energy consumption of fresh air treatment, and the air outlet temperature is lower than the room dew point temperature, and the air outlet is prone to condensation. , and when the airflow organizat...
