Embodiment 1

[0044] A humidity conditioning system comprising:

[0045] The compressor 1, the four-way valve 2, the first heat exchanger 3, the second heat exchanger 5, the throttling element 7, the third heat exchanger 9, the third heat exchanger 9 and the four-way valve are sequentially connected through the refrigerant pipeline. Through valve 2 connection;

[0046] The valve unit is used to switch to the state in which the first heat exchanger 3 and the second heat exchanger 5 are connected in series when the four-way valve 2 is switched to the cooling state. The first heat exchanger 3 and the second heat exchanger 5 is a condenser, and the third heat exchanger 9 is an evaporator;

[0047] Total heat exchanger 11;

[0048] Adsorption runner 12;

[0049] The exhaust fan 13 is used to discharge the indoor return air RA through the total heat exchanger 11, the first heat exchanger 3, the adsorption runner 12 and the second heat exchanger 5 in sequence;

[0050] The air supply fan 14 is...

Embodiment 2

[0104] The difference between this embodiment and Embodiment 1 is that the valve unit of this embodiment lacks the third on-off element 6 .

[0105] The valve unit is used to switch to the state where the refrigerant flows through the second heat exchanger 5 and does not flow through the first heat exchanger 3 when the four-way valve 2 is switched to the heating state. The first heat exchanger 3 and the second heat exchanger The heat exchanger 5 is an evaporator, and the third heat exchanger 9 is a condenser.

[0106] Specifically, the valve unit includes:

[0107] The first on-off element 4 is located between the first heat exchanger 3 and the second heat exchanger 5;

[0108] The second on-off element 10, one end of the second on-off element 10 is connected between the second heat exchanger 5 and the first on-off element 4, and the other end of the second on-off element 10 is connected to the four-way valve 2 and the first on-off element 4. Between one heat exchanger 3;

Abstract

The invention relates to a humidity adjusting system which comprises a heat pump air conditioning system and an adsorption type rotating wheel, humidity adjustment of fresh air is achieved, a first heat exchanger and a second heat exchanger are connected in series in the refrigeration and dehumidification process, indoor return air firstly flows through the first heat exchanger, and full high-temperature-difference heat exchange between the first heat exchanger and air is achieved to increase the desorption temperature in front of the rotating wheel; therefore, the efficient performance of the rotating wheel during refrigeration and dehumidification is realized; and optimization of the system loop of the fresh air dehumidification air conditioning system with the rotating wheel is achieved.

Description

technical field [0001] The invention relates to the technical field of humidity regulation, in particular to a humidity regulation system. Background technique [0002] The existing indoor air is generally temperature-regulated by air conditioners. After a period of time, the oxygen concentration in the closed indoor space decreases and the carbon dioxide concentration increases, resulting in poor indoor comfort. Therefore, it is necessary to introduce outdoor fresh air, which is now generally used through total heat exchange. The temperature and humidity can be regulated by the air conditioner and the adsorption rotor, and the temperature adjustment only through the total heat exchanger cannot maximize the dehumidification / humidification capacity of the adsorption rotor. Contents of the invention [0003] The invention provides a humidity regulating system, which solves the technical problem in the prior art that temperature regulation through a total heat exchanger canno...
