Marine air-conditioning system and control method thereof

Abstract

The invention belongs to the field of marine air conditioning, and discloses a marine air-conditioning system and a control method thereof. The marine air-conditioning system comprises a variable-flow-rate water pump and an air-conditioning heat transfer unit which are mutually connected. The output end of the air-conditioning heat transfer unit is connected with the input end of the variable-flow-rate water pump through a refrigerant pipeline and a heating-medium pipeline, a first refrigerant water switching valve, a refrigerant water cooler and a second refrigerant water switching valve are sequentially arranged on the refrigerant pipeline in the flowing direction of refrigerant water, and a first heating-medium water switching valve, a heating-medium water heater and a second heating-medium water switching valve are sequentially arranged on the heating-medium pipeline in the flowing direction of heating-medium water; and the variable-flow-rate water pump is connected with a controller, and the controller is connected with a temperature sensor. According to the marine air-conditioning system, the problems that in the prior art, the number of marine air-conditioning pipelines is large, a vast amount of space of the inner portion of a ship is occupied, and the cost input is large are solved.

Description

technical field [0001] The invention relates to the technical field of marine air conditioning, in particular to a marine air conditioning system and a control method thereof. Background technique [0002] Existing marine air conditioners are divided into two working conditions: cooling and heating. [0003] In the actual process of refrigeration and heating of ship air conditioners, two different media are used for cooling and heating air in the heat exchange unit of the air conditioner, that is, refrigerant water and heat medium water, and the temperature difference between the air to be cooled or heated is also are different, so it is necessary to set the refrigerant water and heat medium water to the corresponding flow rates according to the actual situation. The solution given in the prior art is to set the refrigerant water pump to transport the refrigerant water to the air conditioning heat exchange unit through the refrigeration pipeline system. Exchange heat with t...
