Marine cold and hot water unit of internal combustion engine kinetic energy water source heat pump

Abstract

The invention provides a marine cold and hot water unit of an internal combustion engine kinetic energy water source heat pump, wherein the marine cold and hot water unit of the internal combustion engine kinetic energy water source heat pump is designed for air conditioner configuration of multi-air conditioner cabin ships and yachts. An indirect-type central air-conditioning system can be constituted by a fan coil, a circulating water pump, an automatic water replenishing valve, an expansion tank, a circulating water pipeline and the like which are matched with the central air-conditioning terminal. A belt pulley driving-type shaft-driven compressor and a belt pulley type cooling water pump are selected and are driven by an internal combustion engine directly, and the energy loss processthat according to a conventional power supply air conditioning module cold and hot water unit, the generating unit mechanical energy is converted into electric energy, and then the electric energy isconverted into air conditioning unit compressor mechanical energy is omitted. According to ship and yacht cabin air conditioner required variable energy, the output power and rotary speed of the operation unit internal combustion engine can be automatically adjusted, and the output power of the compressor is controlled to achieve cold and hot water unit stepless energy adjusting. The scheme thata direct-current generator which is driven by the internal combustion engine as well and an alternating current/direct current inverter are configured is adopted to meet the requirements of a ship andair conditioning equipment for a direct current power supply and a power supply; and the electric generator function and the air-conditioning module cold and hot water unit function are integrated, and thus the ship and yacht air conditioner installation space and air conditioner equipment weight are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a marine air conditioner for ships and yachts equipped with multi-chambers. Background technique [0002] At present, it is difficult to use a centralized central air conditioner to transport the air conditioning energy to each air-conditioning cabin through the air duct for the multi-cabin ships and yachts built in China. Generally, each air-conditioning cabin of the ship is equipped with an independent integral marine air conditioner ( Direct evaporative all-in-one) or indirect marine central air-conditioning module cold and hot water unit + fan coil unit scheme. Due to the presence of air-conditioning compressors and condensers in the integrated marine air-conditioning scheme, the installation of such air-conditioning in each cabin will take up a lot of cabin space and the air-conditioning operation noise will be very loud. The scheme of indirect marine central air-c...

Problems solved by technology

That is, there is a process of converting mechanical energy into electrical energy and then converting electrical energy into mechanical energy. The energy efficiency ratio between the output power of the internal combustion engine and the output power of air conditioning compression is very low, so the energy loss in this conversion process is also huge.
