Abstract
Description
Technical Field
[0001] This utility model relates to the field of chiller technology, specifically a marine chiller. Background Technology
[0002] A water-cooled chiller unit is a type of cooling equipment that provides chilled water at constant temperature, constant flow, and constant pressure. Its working principle involves first injecting a certain amount of water into an external heat exchanger, where the water is cooled by the refrigeration system. Then, a water pump delivers the low-temperature chilled water to the equipment requiring cooling. The chilled water carries away heat, its temperature rises, and it flows back to the water tank, thus achieving the cooling effect.
[0003] Chinese utility model patent CN206618144U discloses a marine modular water-cooled chiller, comprising a frame and a chiller module. The frame includes an upper space and a lower space. The chiller module includes a compressor, a plate evaporator, a plate condenser, an expansion valve, a ball valve, an energy regulating valve, a sight glass, and a dryer filter. The compressor is fixedly installed in the lower space, while the plate evaporator and plate condenser are fixedly installed in the upper space. The output port of the plate evaporator is connected to the compressor's suction port, and the compressor's discharge port is connected to the plate condenser's input port. The output port of the plate condenser is connected to the plate evaporator's input port via a ball valve, a dryer filter, a sight glass, and a thermal expansion valve. A needle valve is connected to the plate condenser's output port. This utility model marine modular water-cooled chiller unit adopts a modular design, which can shorten the production cycle, reduce costs, and allows for flexible combination during use. However, the above solution also has the following shortcomings: the structural volume is relatively large, which is not conducive to the miniaturization of the equipment. Utility Model Content
