Problems solved by technology

[0006] However, in Patent Document 1, the fixed position of the temperature sensor on the outer peripheral surface of the header header is positioned using a positioning member, without considering the state of the refrigerant flowing in the header header.
Therefore, when the number of heat transfer tubes is small and a temperature sensor is installed at the inlet of the subcooling line, the temperature of the two-phase refrigerant cannot be measured.

Abstract

This heat source-side unit is installed in an inter-column connection member in which a temperature sensor is positioned higher than an intermediate position in a vertical direction of a heat exchanger, among inter-column connection members.

Description

technical field [0001] The present invention relates to a heat source side unit equipped with a heat exchanger including a header, and a refrigeration cycle apparatus including the heat source side unit. Background technique [0002] A heat exchanger is mounted on a heat source side unit included in a refrigeration cycle device such as an air conditioner or a water heater. Generally, in order to reduce the pressure loss of the refrigerant flowing in the heat transfer tubes, the heat exchanger has a flow path (path) in which a plurality of heat transfer tubes are arranged in parallel. A header corresponding to the number of paths is provided at the refrigerant inlet and the refrigerant outlet of each heat transfer tube. In addition, a temperature sensor for measuring the temperature of the refrigerant flowing through the heat transfer tubes may be provided in the header. [0003] As such a heat exchanger, for example, the following heat exchanger has been proposed, that is,...
