High-accuracy energy-saving constant-temperature constant-moisture air conditioner and control method thereof

Abstract

The invention relates to a High-accuracy energy-saving constant-temperature constant-moisture air conditioner and a control method thereof. The air conditioner comprises a compressor in an air conditioner shell and devices arranged at an air outlet, wherein the devices arranged at the air outlet include an air blower, an electric moistener, an electric heater and a temperature and moisture sensor. An exhaust duct of the compressor is connected with the temperature and moisture sensor which comprises M+1 reheating electromagnetic valves, M reheating condensers with different condensing areas, subcooling condenser, N-1 refrigeration electromagnetic valves and N evaporators with identical heat exchanging areas which are sequentially connected, wherein M and N are from 2 to 10. By additionally arranging the reheating condensers and the evaporators, the invention has dual action of energy saving and environmental protection by recovering the condensing heat of the system and lessening the waste heat emission of the unit so that the season efficiency ratio of the compressor unit can be further improved. The reheating condensers and the reheating electromagnetic valves at a bypass pipeline are switched and matched with the high-accuracy comprehension adjustment of the electric heater and the electric moistener so that the whole air conditioner can obtain high-accuracy temperature and moisture control.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a high-precision energy-saving constant temperature and humidity air conditioner and a control method thereof. Background technique [0002] At present, constant temperature and humidity air conditioners are widely used in tobacco, hospitals, food processing, printing factories, computer room warehouses and other places that have high requirements for temperature and humidity. The constant temperature and humidity air conditioner in the prior art adopts a refrigeration system for excessive cooling and dehumidification, and then uses electric heating to reheat and raise the temperature to offset the excessive cooling capacity, and uses a humidifier to perform humidity compensation to offset the excessive dehumidification capacity. , try to avoid compressor shutdown in order to maintain a high-energy-consuming operation mode that precisely controls the temperature and humidity of the space. ...

AI Technical Summary

Problems solved by technology

However, the structure emits a large amount of condensation heat to the atmosphere during operation, and the dissipation of this heat increases the temperature of the surrounding environment, causing serious environmental thermal pollution.

And its control accuracy of temperature and humidity is low
