Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 Shown is a fresh air treatment device combined with condensation dehumidification and solution dehumidification, including an air circulation system (also called an air supply and exhaust system), two vapor compression refrigeration cycles and a solution regeneration cycle.

[0036] The air circulation system includes four air ducts of a total heat exchanger 1, a return air duct, a fresh air duct, a supply air duct and an exhaust air duct, and two blowers.

[0037] The total heat exchanger 1 is placed between the four air ducts, the upper and lower air inlets are respectively opened to the return air duct and the fresh air duct, and the upper and lower air outlets are respectively opened to the air supply duct and the exhaust air duct;

[0038] In the air supply duct, the surface cooler 3, the solution dehumidifier 10 and the first fan 16 are p...

Abstract

The invention discloses a condensing dehumidification and solution dehumidification combined fresh air treatment device and method. According to the device and method, an air circulation system, two refrigerant circulations and two solution circulations are included; after fresh air and return air are subjected to full heat exchange, condensing dehumidification is conducted through a surface air cooler firstly, and dehumidification and thermoregulation are conducted through a solution dehumidifier till the ideal air supply state is reached; the return air and the other part of fresh air are used for solution regeneration and condensation heat treatment, and dynamic matching of the heat among key components in the device and solution parameters along with fresh air treatment load changes can be achieved by adjusting the fresh air flow of an exhaust duct; selective permeable membrane cores are adopted for both the solution dehumidifier and a regenerator, and supplied air and exhausted air with liquid can be avoided; and the energy-saving effect of the device is remarkable, and the problems that by means of a conventional solution dehumidification air treatment device, the operating parameters are difficult to match, liquid is carried, and the air supply parameter control is not precise are solved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of refrigeration and air-conditioning systems, in particular to a solution dehumidification fresh air heat and humidity treatment device and method driven by a heat pump. Background technique [0002] In order to meet the diversified needs of building functions, the fresh air sent to various buildings must be processed by air treatment devices, and can only be sent indoors after reaching a certain temperature and humidity value. At present, when the air conditioner performs cooling and dehumidification treatment on the fresh air, the method adopted is mostly the mechanical dew point cooling and dehumidification method. That is, the temperature and humidity coupling control method is adopted, and the cold source medium in the surface cooler is used to simultaneously cool and condense and dehumidify the fresh air. One disadvantage of this traditional fresh air treatment method is tha...
