Title:
EVAPORATIVE CONDENSING UNIT AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/056943
Kind Code:
A1
Abstract:
An evaporative condensing unit and a control method therefor. The evaporative condensing unit comprises: an indoor heat exchange pipe (20) comprising a compressor (21) and an indoor heat exchange unit (22) communicated with the compressor (21) by means of a pipe; a first outdoor heat exchange pipe (40) comprising a first outdoor heat exchange unit (41); and a second outdoor heat exchange pipe (60) comprising a second outdoor heat exchange unit (61). The indoor heat exchange pipe (20) is selectively communicated with the first outdoor heat exchange pipe (40) to form a refrigerating loop or with the second outdoor heat exchange pipe (60) to form a heating loop. According to the evaporative condensing unit above, a refrigerating loop and a heating loop different in route are employed for a refrigerating mode and a heating mode. This is different from the prior art in which one loop is shared by the two modes. Therefore, different advantages of the first outdoor heat exchange pipe (40) and the second outdoor heat exchange pipe (60) can be utilized separately, thereby solving the problem in a conventional evaporative condensing unit of being unable to achieve both good refrigerating effect and good heating effect. Said evaporative condensing unit has both good refrigerating effect and good heating effect.
