Title:
ROOFTOP UNIT
Document Type and Number:
WIPO Patent Application WO/2017/094391
Kind Code:
A1
Abstract:
The rooftop unit to be installed on a vehicle roof is equipped with multiple exterior heat exchangers (16, 18, 19, 15A, 15B), a front opening formation part (122), and a blower (131). The multiple exterior heat exchangers are arranged in a vehicle advancing direction and cool a refrigerant by means of heat exchange between the refrigerant and outside air. The front opening formation part is disposed on the vehicle-advancing-direction front side with respect to the multiple exterior heat exchangers and forms a front opening (122a) through which the outside air is taken in from the vehicle-advancing-direction front side. The blower is disposed at a vertical position above the exterior heat exchanger (15A, 16) located at the foremost position in the vehicle advancing direction. The blower generates a flow of the outside air in such a manner that the outside air taken in through the front opening passes through the foremost exterior heat exchanger, and the blower sucks in the outside air passed through the foremost exterior heat exchanger. The vehicle-advancing-direction front side of the foremost exterior heat exchanger is positioned higher in the vertical direction than the vehicle-advancing-direction rear side of the exterior heat exchanger, and the foremost exterior heat exchanger is inclined with respect to the vehicle advancing direction.
