Triple type condensation device for ship air conditioner

Abstract

The invention relates to a triple type condensation device for a ship air conditioner, comprising a compressor, an evaporator and a condenser, wherein the condenser comprises a shell, as well as a left end cover and a right end cover which are connected to the shell; a high pressure gas inlet communicated with an inner cavity of the shell is arranged at the upper part of the shell; a high pressure gas outlet communicated with the inner cavity of the shell is arranged at the bottom of the shell; a condensation heat exchange tube and a super-cooling and superheating heat exchange tube both penetrate through the inner cavity of the shell, and two ends of the condensation heat exchange tube and the super-cooling and superheating heat exchange tube are respectively supported to the left end cover and the right end cover; a refrigerant steam outlet of the compressor is connected with the high pressure gas inlet on a condenser shell; the high pressure gas outlet at the bottom of the condenser shell is connected with an inlet of the evaporator; an outlet of the evaporator is connected with a low pressure gas inlet of the super-cooling and superheating heat exchange tube of the condenser; and a low pressure gas outlet of the super-cooling and superheating heat exchange tube of the condenser is connected with the inlet of the evaporator. The device can effectively improve the gas superheating degree of the compressor inlet and the super-cooling degree of the compressor outlet, reduce the compression ratio and prolong the service life of the compressor.

Description

technical field [0001] The invention relates to refrigeration equipment for air-conditioning units on ships, in particular to a triple-type condensing device for marine air-conditioning. Background technique [0002] The condenser is the main heat exchange equipment in the refrigeration and air-conditioning device. Its quality directly affects the overall performance of the refrigeration and air-conditioning equipment. At the same time, the condenser is also one of the most important components in the system. It is responsible for the condensation of high-temperature and high-pressure refrigerant gas into liquid. The task is also a component for heat exchange between the refrigerant cycle and the cooling water cycle. [0003] In the existing condenser, after the liquid refrigerant absorbs the heat of the cooled object in the evaporator, it is vaporized into a low-temperature and low-pressure steam, sucked by the compressor, compressed into a high-temperature and high-pressur...

AI Technical Summary

Problems solved by technology

The traditional condenser cannot effectively increase the superheat of the compressor inlet. If the problem of increasing the superheat needs to be solved, an additional regenerator needs to be designed, so that the air conditioning unit is large in size, takes up a lot of space, consumes a lot of materials, and costs high
