Marine bank-based dual-refrigerant combined type air conditioner

Abstract

The invention relates to a marine bank-based dual-refrigerant combined type air conditioner. A refrigerating compressor is connected with a heat absorbing flow channel inlet of a plate heat exchanger through an air-cooled condenser, a liquid reservoir and a heating power expansion valve in sequence, the refrigerating compressor is connected with a heat absorbing flow channel outlet of the plate heat exchanger, an air heat exchanger is connected between the heat absorbing flow channel inlet and the heat absorbing flow channel outlet of the plate heat exchanger, a heat emission flow channel inlet of the plate heat exchanger is connected with the air heat exchanger through a heat exchanger water outlet pipe, and a refrigerant water pump communicated with the plate heat exchanger and the air heat exchanger and an air heat exchanger water outlet valve are arranged on the heat exchanger water outlet pipe. The connection and switching of a refrigerant water inlet pipe, a refrigerant water outlet pipe, a water inlet pipe and a water outlet pipe of the air heat exchanger and the plate heat exchanger is adopted, the marine bank-based dual-refrigerant combined type air conditioner is connected with an air conditioning water circulating system and an air circulating system of a vessel, in this way, the refrigeration function of air cooling or water cooling of a marine air conditioner after the vessel is berthed is achieved, the requirements for local area comfort, temperature reduction and dehumidification of the vessel are met, and the production and living demands in necessary equipment and cabins are met when the vessel is maintained or berthed in a dock.

Description

Technical field [0001] The invention relates to a marine air conditioner, in particular to a dual-refrigerant combined air conditioner that provides refrigerant water or cold air on a shore-based marine. Background technique [0002] When the ship is at the dock or entering the dock for repairs, the boiler or generator on the ship stops working to generate electricity, the marine air conditioning device does not work for a long time, and the humid air equipment easily corrodes the marine equipment, which greatly increases the failure rate of electronic equipment. If when docking at the terminal, the boiler or generator is turned on for the electronic equipment compartment or the individual compartment used separately, it will consume a large amount of coal or fuel oil, high energy consumption and high use cost. Summary of the invention [0003] In order to solve the problem of the use of marine air conditioners after ships docked in the prior art, the present invention provide...

AI Technical Summary

Problems solved by technology

If the marine air-conditioning device is turned on to start the boiler or generator for the electronic equipment cabin or individual cabins used alone when docking, it will consume a large amount of coal or fuel oil, resulting in high energy consumption and high operating costs.
