ばならない。A cylindrical heat exchanger whose outer cylinder is made of resin expands and contracts in the axial direction of the heat exchanger due to temperature differences. For example, if the resin heat exchanger is used as a load-side heat exchanger in a heat pump system, it will work as an evaporator during cooling operation and the heat exchanger temperature will be around 7C, and during heating operation it will work as a condenser and reach around 45C. becomes. The temperature difference is about 38 degrees. If the total length of the heat exchanger is 15001 rrIn, expansion and contraction of about 7.5 tran will occur. Therefore, it is necessary to avoid fixing the upper and lower ends of the cylindrical heat exchanger so that they cannot be moved.

The figure is a configuration diagram of a unit of a water-cooled heat pump system. A compressor 2 for a refrigerant circuit, a circulation pump 3 for circulating cold water on the load side, a heat exchanger 4 on the load side, and a heat exchanger 5 on the heat source side are built into the main body frame 1. A refrigerant circuit connecting the load side heat exchanger 4 and the heat source side heat exchanger 5 allows heat to be discarded from the load side to the heat source side during cooling operation, and heat is given from the heat source side to the load side during heating operation. .

熱膨張による伸縮が問題となる。When the heat exchanger is cylindrical as shown in the figure and the outer cylinder 6 is made of resin to prevent corrosion and cost reduction, expansion and contraction due to thermal expansion in the axial direction of the outer cylinder 6 becomes a problem.

、安定確実に熱交換器を固定できる。According to the present invention, the heat exchanger can be attached to the main body frame so as to be extendable in the axial direction. The heat exchanger lower member 7 is securely attached to the main frame 1 with bolts 8 and the like, and the upper part is secured with a band 9 to prevent it from flexing during transportation and to allow expansion and contraction in the axial direction. With the above configuration, the heat exchanger can be fixed stably and reliably regardless of differences in operating conditions.

換器の伸長を吸収しうる。According to the present invention, since the cylindrical heat exchanger can be fixed so as to be expandable and contractible in the axial direction, expansion of the heat exchanger due to differences in operating conditions such as heating and cooling can be absorbed.
