Title:
HEAT SOURCE UNIT
Document Type and Number:
WIPO Patent Application WO/2016/171177
Kind Code:
A1
Abstract:
The present invention achieves reductions in the number of components and machining cost, efficient arrangement of air heat exchangers or the like, and an improved performance by reducing pressure loss portions in a refrigerant circuit. This heat source unit is provided with a plurality of air heat exchangers (2) in which a plurality of tubes with a refrigerant flowing therethrough are inserted in the thickness direction into radiating fins and connected to the radiating fins, the plurality of air heat exchangers (2) being arranged on top of a machine chamber (1) of a rectangular shape in a plan view in such a manner that the left and right air heat exchangers (2) are further spaced apart toward the upper side and opposed to each other so as to form a V shape when viewed in the transverse direction. The plurality of air heat exchangers (2) comprise first to fourth air heat exchangers (2A to 2D), which are each formed in an L shape by bending one end in the direction in which the tubes extend, the L shape comprising a long-side portion (2a) and a short-side portion (2b). Each of the short-side portions (2b) is disposed on the transverse side of the rectangle so that the installed shape of the first to fourth air heat exchangers becomes a rectangular frame in a plan view.
