Title:
AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/224014
Kind Code:
A1
Abstract:
An air-conditioning system (1), comprising an outdoor unit (2) and an indoor unit (3) sequentially arranged in a direction from high to low, wherein the outdoor unit (2) comprises a condenser, and the indoor unit (3) comprises an expansion valve. The air-conditioning system (1) further comprises a pressure reduction module (5) arranged between the condenser and the expansion valve. The condenser, the pressure reduction module (5) and the expansion valve are sequentially connected by means of a liquid pipeline (4), and the pressure reduction module (5) is used for adjusting the flow of condensate in the liquid pipeline (4), so as to control upstream pressure borne by the expansion valve to be within a safe pressure range. The expansion valve of the air-conditioning system (1) has a relatively long service life, and therefore, the air conditioning system (1) works relatively reliably.
