Detailed Description
In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Example 1
The embodiment provides an air conditioning unit with a pressurizing module box, as shown in fig. 1, comprising an indoor unit, an outdoor unit, and a pressurizing module box installed between the indoor unit and the outdoor unit. The pressurizing module box comprises a ball valve, a dry filter, a first liquid storage device, a viewing mirror, a pressurizing pump, a bypass one-way valve and a one-way valve arranged at the outlet of the pressurizing pump. The first liquid storage device is arranged between the booster pump and the outdoor unit and used for storing the liquid refrigerant discharged by the condenser, and the booster pump is arranged between the liquid storage device and the indoor unit and used for providing enough lift for the liquid refrigerant entering the indoor unit. A bypass one-way valve is arranged in the pressurizing module box in parallel with the pressurizing pump, and when the pressurizing pump is not needed, the system can work normally.
