A marine shore-based dual-refrigerant combined 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 which provides refrigerant water or cold air on the shore. Background technique [0002] When the ship is moored at the dock or in the dock for repairs, the boiler or generator on the ship stops working to generate electricity, and the marine air-conditioning device does not work for a long time. The humid air equipment is easy to erode the marine equipment, which greatly increases the failure rate of electronic equipment. If, when docked at the dock, the marine air-conditioning device is turned on to start the boiler or generator for the electronic equipment cabin or individual cabins used alone, it will consume a large amount of coal or fuel oil, with high energy consumption and high use cost. Contents of the invention [0003] In order to solve the problem of using the marine air conditioner after the ship is docked in the prior art, the...
