<P>PROBLEM TO BE SOLVED: To achieve maximum heat exchanger efficiency at cooling/heating operation in a configuration in which a low-cost non-return valve and an optimal absorbing/connecting pipe are disposed. <P>SOLUTION: A plurality of heat exchanger blocks are disposed in at least one of indoor/outdoor heat exchangers. Furthermore, valves are disposed so as to be evaporated and condensed to be parallel and tandem, respectively, and thereby the heat exchanger efficiency is improved to the maximum while all the heat exchanger are used. Accordingly, a freezing cycle device with these characteristics which has the low-cost and high-performance heat exchangers and the optimal absorbing/connecting pipe can be supplied. <P>COPYRIGHT: (C)2013,JPO&INPIT |
