Title:

HEAT PUMP SYSTEM, COMBO WASHER-DRYER, AND DRYER

Document Type and Number:

WIPO Patent Application WO/2016/026226

Kind Code:

A1

Abstract:

Provided are a heat pump system, a combo washer-dryer, and a dryer. The heat pump system comprises an evaporator (3), a compressor (4), a condenser (2), and a refrigerant regulator subsystem (1). The evaporator (3), the compressor (4), the condenser (2), and the refrigerant regulator subsystem (1) are sequentially connected via a pipe to form a refrigerant circulating circuit. The refrigerant regulator subsystem (1) comprises a first branch (11) and a second branch (12) connected in parallel between the evaporator (3) and the condenser (2). The first branch (11) comprises a first throttling apparatus (111) connected at an outlet thereof to an inlet-pipe opening of the evaporator (3) and an reservoir apparatus (114) arranged between the first throttling apparatus (111) and the condenser (2). A second throttling apparatus (121) is connected in series on the second branch (12). The reservoir apparatus (114) allows an increased space for accommodating a refrigerant when the ambient temperature is high, thus preventing a rapid increase in pressure load, and a reduced space for accommodating the refrigerant when the ambient temperature is low, thus allowing a rapid increase in the load of the compressor (4).
