AI Technical Summary

Technical Problem

In the existing refrigerant units, the length of the refrigerant flow path is too long, resulting in large heat loss and the performance of the refrigerant circuit cannot be fully improved.

Method used

A refrigerant unit is designed, and the support member is centrally arranged with a compressor, a heat exchanger and other constituent elements. By optimizing the configuration of the flow channel module, the length of the refrigerant flow channel is shortened, so that the connection portion between the first heat exchanger and the second heat exchanger is offset in the vertical direction.

Benefits of technology

By shortening the length of the refrigerant flow path, heat loss is reduced, the performance of the refrigerant circuit is improved, and more efficient thermal management is achieved.

Abstract

The invention provides a refrigerant unit. In a refrigerant unit in which constituent elements of a refrigerant circuit are unitized, the flow path length of a refrigerant flow path can be shortened, and the performance of the refrigerant circuit can be improved. A refrigerant unit (10) is provided with: a refrigerant circuit having, as constituent elements, a compressor (20), a first heat exchanger (30), decompression devices (71, 72), and second heat exchangers (41, 42); and a single support member (12) that concentratedly supports the constituent elements of the refrigerant circuit, and in the refrigerant unit, the first heat exchanger and the second heat exchanger are disposed with the pressure reduction device interposed therebetween. A connection portion between the first heat exchanger and the refrigerant flow path connected to the pressure reducing device is disposed so as to be offset in the vertical direction with respect to a connection portion between the second heat exchanger and the refrigerant flow path connected to the pressure reducing device.
