Embodiment approach

[0041] The inner pipe 11 of the regenerator is connected to the high-pressure liquid storage tank 3 , and the branch pipe 12 a of the outer pipe 12 of the regenerator is connected to the subcooling valve 2 .

[0042] The specific working process of the first preferred embodiment of the application of the regenerator in the present invention:

[0043] The outdoor heat exchanger starts to work, and the refrigerant in the outdoor heat exchanger flows into the high-pressure liquid storage tank 3 through the one-way valve. The refrigerant in the high-pressure liquid storage tank 3 reaches the regenerator 1 through two paths. One way is to enter the regenerator inner pipe 11 through the regenerator inner pipe 11 connected with the high-pressure liquid storage tank 3 . The other way is to enter the space of the outer pipe body of the regenerator through the supercooling valve 2 and the branch pipe 12a of the outer pipe 12 of the regenerator. The outlet of the inner pipe 11 of the r...

Abstract

The invention discloses an air conditioning regenerative device which is used between a high pressure liquid storage tank and a liquid pipe stop valve. The device comprises a regenerator and a supercooling valve for adjusting liquid flow in the regenerator. The invention also discloses an air conditioning regenerative control method which comprises following steps: 1) a detection of an outlet temperature of the regenerator; 2) a detection of a pressure of a refrigeration valve; 3) a determination of a saturation temperature according to a comparison of the pressure with a thermodynamics saturation temperature indicator; 4) a judgment that whether a temperature of an outlet of a main pipe of the regenerator is in a preserved ranged of the saturation temperature, if so, a process is finished; if not, an opening of the refrigeration valve is adjusted, and the step 1 is executed. The invention provides the air conditioning regenerative device and the air conditioning regenerative control method for controlling a stability of the system and improving a heat exchanging effect of air conditioning.

Description

technical field [0001] The invention relates to an air conditioner heat recovery device and a control method thereof. Background technique [0002] At present, air conditioners generally use refrigerants with better heat exchange effects as refrigerants. However, since the pressure of the refrigerant with good heat exchange effect is relatively high and the flow rate is relatively fast, this will affect the heat exchange effect. Therefore, although the existing air conditioner has adopted the refrigerant with better heat exchange effect, it has not obtained good heat exchange effect. [0003] In the prior art, an air-cooled central air conditioner is provided with a regenerator between the condenser and the evaporator, which increases the heat exchange effect of the system. [0004] The application number is 02288785.7, and the Chinese utility model patent titled "circulation system combining double-effect combined cooling and heating absorption machine and solution dehumi...
