Problems solved by technology

However, since the length of the refrigerant passage becomes too long, the pressure drop due to passage through the evaporator increases sharply, thereby greatly reducing the system efficiency
In addition, in the structure of prior art 3, since the refrigerant in the first evaporator enters the second evaporator, the evaporation pressure rises too much, thereby reducing the system efficiency

Embodiment Construction

[0055] image 3 is a diagram of a multiple evaporation system according to the present invention. Like a common air-conditioning system, the multi-evaporation system of the present invention includes: a compressor 10 that sucks and compresses refrigerant; a condenser 20 that liquefies the refrigerant compressed in the compressor 10; a throttling expansion device; and an evaporator 40 for evaporating the throttled refrigerant in the expansion device 30 . Such as image 3 As shown, the refrigerant discharged from the evaporator 40 flows into the compressor 10 again, so that the refrigerant is circulated. The multi-evaporation system of the present invention has a passage connecting the expansion device 30 , the evaporator 40 and the compressor 10 , and also includes a detection device 70 for detecting the temperature and pressure of the refrigerant to control the expansion device 30 .

[0056] In the configuration of the expansion device 30 and the evaporator 40, the multi-ev...

Abstract

The present invention relates to a multi-evaporation system which improves the efficiency of a vehicle air conditioning system by multiple evaporations during the cooling cycle of the system. An object of the present invention is to provide a multi-evaporation system which enhances cooling efficiency and system efficiency by multiple evaporations using a plurality of evaporation units disposed in parallel. Another object of the present invention is to provide a multi-evaporation system which further enhances cooling efficiency and system efficiency by additionally equipping the evaporation system with an ejector and thereby mixing coolants and improving the coolant temperature conditions.

Description

technical field [0001] The present invention relates to a multi-evaporation system, and more particularly, to a multi-evaporation system that performs a multi-evaporation process in an air conditioning cycle of a vehicle air conditioning system, thereby enhancing system efficiency. Background technique [0002] In the automotive industry, as global concerns about energy and the environment have generally increased, the efficiency of various components including fuel efficiency has been steadily improved, and the appearance of vehicles has been diversified in order to meet the various needs of customers. need. In accordance with such trends, research and development has been conducted on various vehicle components that are lighter in weight, smaller in size, and multifunctional. In particular, in an air conditioning unit of a vehicle, since it is generally difficult to secure a sufficient space in an engine room, much effort has been made to manufacture an air conditioning s...
