| Zusammenfassung: | A heat exchanger unit having plate heat exchangers, wherein pressure loss and refrigerant distribution performance of each plate heat exchanger are appropriately determined to enhance the performance coefficient of the entire heat exchanger unit. This is achieved by a simple and inexpensive structure. A heat exchanger unit is constructed by serially interconnecting plate heat exchangers. The refrigerant distribution function of each plate heat exchanger is set such that, when the heat exchanger unit functions as an evaporator, the distribution function of refrigerant distribution mechanisms of plate heat exchangers on the refrigerant upstream side is higher than the distribution function of refrigerant distribution mechanisms of plate heat exchangers on the refrigerant downstream side and, when the heat exchanger unit functions as a condenser, the distribution function of the refrigerant distribution mechanisms of the plate heat exchangers on the refrigerant upstream side is lower than the distribution functi |
