Temperature and humidity independent control air conditioning device based on distributed fresh air treatment unit and treatment method thereof

Abstract

The invention relates to a temperature and humidity independent control air conditioning device based on a distributed fresh air treatment unit and a treatment method thereof. The air conditioning device comprises an indoor unit for treatment of indoor return air, an indoor sensible heat terminal for indoor temperature regulation, an outdoor unit and connecting pipelines; the indoor unit comprisesa high-temperature pre-cooling module for pre-cooling return air and a low-temperature dehumidifying module for dehumidifying; the indoor sensible heat terminal comprises a sensible heat terminal coil pipe; the outdoor unit comprises a high-temperature refrigeration device which is connected with the high-temperature pre-cooling module and a low-temperature refrigeration device which is connectedwith the low-temperature dehumidifying module; Thus, the device and method of the invention can effectively meet the demand of fresh air treatment by combining with distributed fresh air treatment method, and meet the demand of indoor temperature and humidity control by using independent return air treatment unit and sensible heat terminal equipment, which can be applied to various public buildings, etc. It can better meet the demand of fresh air treatment, temperature and humidity regulation, and realize the efficient operation of air conditioning equipment.

Description

technical field [0001] The invention belongs to the field of energy, and in particular relates to an air-conditioning device with independent temperature and humidity control and a processing method thereof based on a distributed fresh air processing unit in the field of HVAC devices. Background technique [0002] The regulation process of the indoor thermal and humid environment of buildings includes the regulation of indoor temperature and humidity. Conventional air-conditioning devices usually use a single cold source to realize the regulation of temperature and humidity at the same time. The time-by-hour changes of indoor sensible heat load and humidity load make it impossible to effectively regulate the building's thermal and humid environment. As a new type of air conditioner, the temperature and humidity independent control air conditioner uses different means to adjust the indoor temperature and humidity: by sending dry air to bear the indoor humidity load and adjust...

AI Technical Summary

Problems solved by technology

[0004] From the above background technology, there is no temperature and humidity independent control air conditioner that independently controls the fresh air treatment, temperature and humidity adjustment.
