Problems solved by technology

At present, although there are solution dehumidification devices used in combination with air conditioning systems, because the solution needs to reach a certain temperature during the repeated regeneration process, the existing solution dehumidification technology often needs to be completed by configuring additional heating devices and consuming a lot of electricity. Regeneration cycle, which undoubtedly increases the cost of use and limits the promotion and use of solution dehumidification technology

Abstract

The invention discloses an electrochemical temperature and humidity adjustment air conditioning system and a control method, and belongs to the field of air conditioners. The air conditioning system comprises a solution heat exchanger; a first heat exchanger is connected into a pipeline between a first fluid outlet and a second fluid inlet of the solution heat exchanger, and a second heat exchanger is connected into a pipeline between a second fluid outlet and a first fluid inlet to form a solution circulating heat exchange loop; and the heat exchange of three mediums of solution, refrigerantsand air is finished in the first heat exchanger and the second heat exchanger to realize adjustment of the temperature and the humidity of the air flowing through the first heat exchanger and the second heat exchanger. The air conditioning system realizes the regeneration cycle of the solution by effectively using ECC self heat conversion without increasing the energy consumption; and the solution is circulated in the solution circulating heat exchange loop in one direction, so that the control is simple. Indoor air is dehumidified during refrigerating; and the indoor air is humidified duringheating.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an electrochemical temperature and humidity adjustment air conditioning system and a control method. Background technique [0002] With the improvement of people's living standards, people are paying more and more attention to the quality of the indoor environment. Indoor humidity is also used as a criterion for judging the comfort of the indoor environment. Too high or too low humidity will destroy the comfort of the indoor environment. [0003] At present, conventional air conditioners only have a dehumidification function. The dehumidification function is dehumidification by condensation dehumidification. The air is conditioned by condensation. The heat-humidity ratio of the air-conditioning unit can only be changed within a certain range, which is difficult to adapt to the change of indoor heat-humidity ratio. Humidity provides conditions for the growth of various m...
