Document Type and Number:
WIPO Patent Application WO/2019/146846
Kind Code:
A1
Abstract:
The present invention relates to a multi-stage split independent control cooling system and, more specifically, to a technique in which an evaporator in charge of a cooling system of a bus or a railway vehicle is not made of a single composition and is composed of a plurality of parallel type evaporators such that independent control can be implemented in accordance with cooling adjustment, thereby improving energy efficiency. That is, the present invention relates to a cooling system in which a refrigerant passes through a compressor, a condenser, an expansion valve, and an evaporator to implement heat exchange, wherein the evaporator is divided into a plurality of evaporators and the divided evaporators are coupled to a plurality of refrigerant pipes distributed in the expansion valve, respectively, so as to be independently operated through a control portion, and evaporator fans are installed at one side of each of the evaporators such that interlock control can be implemented in accordance with the operation of the evaporator.
