Title:
HEAT SOURCE UNIT AND AIR CONDITIONER HAVING THE HEAT SOURCE UNIT
Document Type and Number:
WIPO Patent Application WO/2018/147414
Kind Code:
A1
Abstract:
Heat source unit (2) for an air conditioner (1) comprising a refrigerant circuit, the heat source unit comprising an external housing (10) accommodating a compressor (3) to be connected to the refrigerant circuit; a heat source heat exchanger (5) to be connected to the refrigerant circuit and configured to exchange heat between a refrigerant circulating in the refrigerant circuit and a heat source (104); an electric box (30) having a top (31) and side walls (32 to 34), the electric box accommodating electrical components (36) to configured to control the air conditioner and having an air passage (37) comprising an air inlet (38) and an air outlet (39), an air flow (41) being induced through the air passage from the air inlet to the air outlet for cooling at least some of the electrical components, wherein a cooling heat exchanger (22) is accommodated in the external housing and to be connected to the refrigerant circuit, wherein the cooling heat exchanger (22) is arranged so as to be flown through by the air flow (41) and exchange heat between the refrigerant and the air flow, the cooling heat exchanger (22) being connected to a bypass line (24) branched from a liquid refrigerant line (25) and a gas suction line (26), wherein the bypass line (24) has a valve (20) upstream of the cooling heat exchanger; and a controller (65) configured to control the valve (20) in an OFF-mode in which the valve (20) is closed and an ON-mode in which the valve (20) is opened.
