Embodiment Construction

[0031] The core of the present invention is to provide a water-cooled air-conditioning system for ships, so as to effectively protect heat exchangers and compressors while ensuring the quality of heat supply in cabins and lockers.

[0032] Another core of the present invention is to provide a control method for the water-cooled air-conditioning system of the above-mentioned ship.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] Please also refer to figure 1 and figure 2 , the ship water-cooled ai...

Abstract

The invention discloses a water-cooling air-conditioner system for ships. The water-cooling air-conditioner system comprises a compressor, a condenser and an evaporator, wherein the condenser is used for seawater heat exchange, and the evaporator is arranged inside a ship compartment or a storage cabinet. The water-cooling air-conditioner system further comprises a first temperature sensor, an electric heater and a controller, wherein the first temperature sensor is used for detecting the water inlet temperature Ta of a water inlet of the condenser, the electric heater is arranged inside the ship compartment or the storage cabinet, and the controller controls the compressor to stop running and controls the electric heater to be started when the Ta is smaller than T1 on the heating condition. According to the water-cooling air-conditioner system, the phenomenon that low-voltage protection appears repeatedly on the system is effectively avoided, so that the air-conditioner system supplies heat into the ship compartment and the storage cabinet continuously; the compressor is made to stop running in time when at low temperature, so that the risk that the heat exchanger is split due to frosting and the compressor is burnt out is effectively lowered. The invention further discloses a control method for the water-cooling air-conditioner system for ships.

Description

technical field [0001] The invention relates to the technical field of marine air-conditioning, and more specifically, to a water-cooled air-conditioning system for ships and a control method thereof. Background technique [0002] Whether it is the passenger space inside the ship or the storage space inside the ship, it is necessary to maintain a suitable temperature, which requires the continuous work of the air conditioning system installed on the ship. [0003] In order to make full use of the environmental conditions and reduce the cost of heating and cooling, the existing air-conditioning systems of ships are generally designed as water-cooled air-conditioning systems, in which the water used for heat exchange with the refrigerant is seawater taken locally, seawater The temperature in the summer is significantly lower than the temperature of the external environment, so its energy-saving advantage is very obvious in the summer cooling process. Usually, the cooling proce...
