Low-temperature regeneration combined type turning wheel dehumidifying unit

Abstract

The invention discloses a low-temperature regeneration combined type turning wheel dehumidifying unit. The low-temperature regeneration combined type turning wheel dehumidifying unit comprises a double-air-channel air system composed of an air regeneration channel and an air processing channel. The low-temperature regeneration combined type turning wheel dehumidifying unit further comprises a refrigerating device, a dehumidifying turning wheel, a feeding fan and a regeneration fan. The refrigerating device comprises a compressor, a reheating condenser, a first electromagnetic valve, a second electromagnetic valve, a bypass condenser, a check valve, a throttling component and an evaporator. According to the low-temperature regeneration combined type turning wheel dehumidifying unit, condensation heat provided by the reheating condenser of the refrigerating device contained in the unit serves as regeneration heat of the dehumidifying turning wheel, so that the regeneration temperature is low and regeneration sources with high regeneration temperature traditionally provided by steam, high-temperature hot water and electric heating are replaced. The energy consumption of the unit is greatly reduced and equivalently almost free turning wheel dehumidifying is conducted on the basis of cooling dehumidifying, the resource utilization rate is increased, and thus the energy efficiency ratio of the unit is increased.

Description

technical field [0001] The invention relates to an air-conditioning unit, in particular to a low-temperature regeneration compound dehumidification unit with a rotary wheel. Background technique [0002] Nowadays, shopping malls, hospitals, hotels, airports and gymnasiums and other crowded public buildings have a large humidity load, and humidity will cause many problems, such as: 1) Energy consumption increases, and traditional air conditioners that mainly control temperature have to pass through deep cooling. It consumes a lot of energy to remove the moisture load; 2) poor comfort, the humidity in these places is generally around 70% without control, and the comfortable humidity range for the human body is 40% to 60%; 3) the breeding of bacteria is relatively A shady environment with humidity above 70% is a breeding ground for mold growth. [0003] According to the current national standards, public buildings need to ensure the minimum amount of fresh air, but how to redu...

Problems solved by technology

[0006] The traditional rotary dehumidification method uses steam, high-temperature hot water and electric heating as the regeneration heat source. The regeneration temperature is high (100-140°C), and the regeneration energy consumption is high, especially the electric heating, which consumes a lot of power, resulting in high costs.

In addition, after the high-temperature air passes through the regeneration area of ​​the dehumidification wheel, its temperature is still very high, and the high-temperature air is directly discharged, one of which is to cause heat energy loss, and the other is to cause pollution to the environment; in addition, the freezing and dehumidification system using direct evaporation , the heat generated by the condenser is also directly discharged into the air, further causing heat loss and environmental pollution
