Split air conditioner for ship

Abstract

The invention provides a split air conditioner for a ship. The split air conditioner comprises an indoor unit and an outdoor unit, wherein the indoor unit comprises a water containing disc, a centrifugal fan, an evaporator and an expansion valve, wherein the expansion valve is arranged under the evaporator and is connected with the evaporator, the water containing disc is arranged right under the evaporator, the centrifugal fan is arranged above the evaporator, a heater with a temperature control switch is arranged on the upper top surface of the evaporator of the indoor unit, the outdoor unit comprises a compressor, an axial flow fan, a condenser and a drying filter, the condenser is arranged in a position near the air outlet and in a casing of the outdoor unit, the axial flow fan is arranged between the condenser and the air outlet, an outlet of the compressor is connected with an inlet of the condenser, an outlet of the condenser is sequentially connected with the evaporator of the indoor unit through the drying filter, a liquid supply cut-off valve and the expansion valve, and the evaporator is sequentially connected with an inlet of the compressor sequentially through a fluorine cut-off valve and a gas-liquid separator. Through the optimization on the fin materials and the air conditioner structure, the service life of the air conditioner is prolonged, and the split air conditioner is suitable for being used in various kinds of severe environment.

Description

technical field [0001] The invention relates to an air conditioner for ships, in particular to a split air conditioner for ships. Background technique [0002] At present, the split wall-mounted machines that are often equipped on ships are similar to household wall-mounted heat pumps to adjust the air temperature and humidity in the cabin. The temperature difference should not be too large. [0003] When the ship is sailing at sea, the conventionally equipped air conditioners have been exposed to harsh environments such as salt spray and mold for a long time, and the heat exchangers of the indoor and outdoor units will be strongly corroded, resulting in a decrease in the efficiency of the air conditioner, and even a breakdown, which seriously affects the lives of the crew. , production; if the ship encounters waves that cause the hull to shake, the condensed water generated by the conventionally equipped indoor unit will overflow from the water pan when it is cooled,...

AI Technical Summary

Problems solved by technology

[0003] When the ship is sailing at sea, the conventionally equipped air conditioners have been exposed to harsh environments such as salt spray and mold for a long time, and the heat exchangers of the indoor and outdoor units will be strongly corroded, resulting in a decrease in the efficiency of the air conditioner, and even a breakdown, which seriously affects the lives of the crew. , production; if the ship encounters waves that cause the hull to shake, the condensed water generated by the conventionally equipped indoor unit will overflow from the water pan when it is cooled, and the sea is a high-humidity environment. Condensation is prone to occur at the tuyere, which deteriorates the hygienic conditions of the cabin; when heating is required in winter, the working mode of the conventionally equipped air conditioner is heat pump heating, and the electric heating is auxiliary heating. Low temperature or even below minus 20 degrees will cause the condenser of the outdoor unit to freeze, resulting in a serious drop in the heating efficiency of the heat pump, while the heating capacity of the auxiliary electric heating is small and cannot meet the use requirements, resulting in the cabin temperature not meeting the normal life and work requirements of the crew
