Fig. 2 is systemic circulation schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described, but should limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of boats and ships are made up of direct current compressor 1, four-way change-over valve 2, high-voltage switch gear 3, low tension switch 4, First Heat Exchanger 5, direct current list air intake centrifugal blower fan 6, the second heat exchanger 7, stainless steel water pond 10, dual sided outlets 12 and DC control system with speed governing close-coupled air-conditioning unit.Wherein, direct current compressor 1 adopts the input of 24V power supply, and compressor capacity can carry out electrodeless adjusting in 0-5V controls voltage range; Direct current list air intake centrifugal blower fan 6 adopts the outer rotor blower fan of 24V power supply input, and fan delivery can be carried out electrodeless adjusting in 0-10V controls voltage range.24V direct current compressor 1 is separately fixed on stainless steel water pond 10 by heat exchanger support 9 by installation board of compressor 11, the second heat exchanger 7, and 24V direct current list air intake centrifugal blower fan 6, First Heat Exchanger 5 and the second heat exchanger 7 are positioned on same axis and are fixed on successively on stainless steel water pond 10.The parts such as direct current compressor 1, four-way change-over valve 2, First Heat Exchanger 5, the second heat exchanger 7 connect and compose whole cooling cycle system by copper pipe.Low efficient filter screen is established in the inlet side of First Heat Exchanger 5, and water-absorbing sponge is laid in the bottom of water pond 10, and direct current compressor 1 is provided with air intake duct and blast pipe, and air intake duct and blast pipe are equipped with respectively low tension switch and high-voltage switch gear.Whole air-conditioning system is realized automatically and being controlled by nonshared control unit, direct current compressor 1 and direct current centrifugal blower 6 carry out synchronous energy adjusting according to input voltage value is different, accurately control indoor temperature, realize cooling system amount and air output real-time matching, guarantee the reliable and stable operation of compressor.
The utility model adopts special direct-flow air conditioner control system automatically to control.First 24V dc source accesses in compressor control plate, is converted to three phase mains and is input to the end of incoming cables of compressor after ovennodulation, phase-splitting.The control signal of DC fan, direct current sea pump and direct current compressor is controlled by an other control circuit board, can realize the step-less adjustment of blower fan and compressor energy by changing the input voltage value of blower fan and compressor.In order to ensure the reliable and stable operation of air-conditioning system, blower fan and compressor are realized adjusted in concert, and real-time matching prevents compressor band liquid and overheated operation.
Air conditioner assembly of the present utility model has four-way change-over valve to have refrigeration, heats two kinds of functions, and its systemic circulation principle as shown in Figure 2.When refrigeration, cold-producing medium is compressed to high temperature, gases at high pressure and after four-way change-over valve 2, enters the second heat exchanger 4 after direct current compressor 1, and seawater is through the water pump liquid that the second heat exchanger 4 is HTHP by the refrigerant cools of high temperature, high pressure of flowing through.High-temperature high-pressure refrigerant liquid enters First Heat Exchanger 5 become gas-liquid mixture fluid after capillary 8 reducing pressure by regulating flows after, after First Heat Exchanger 5 inner refrigerant liquid absorption external heats, be evaporated to cryogenic gas, in compressor 1, complete whole kind of refrigeration cycle finally by crossing to be inhaled into after four-way change-over valve 2.While heating, cold-producing medium is compressed to high temperature, gases at high pressure and after four-way change-over valve 2, enters First Heat Exchanger 5 after direct current compressor 1, room air is raise by First Heat Exchanger 5 temperature after heating, and the cold-producing medium in First Heat Exchanger 5 is cooled to the liquid of HTHP.High-temperature high-pressure refrigerant liquid enters the second heat exchanger 4 become gas-liquid mixture fluid after capillary 8 reducing pressure by regulating flows after, heat in the second heat exchanger 4 inner refrigerant liquid absorption seawater becomes cryogenic gas, completes the whole circulation that heats finally by crossing to be inhaled into after four-way change-over valve 2 in direct current compressor 1.
The foregoing is only preferred embodiments of the present utility model, be not used for limiting practical range of the present utility model.Under any, in technical field, have and conventionally know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations, therefore protection domain of the present utility model should be as the criterion with claims institute confining spectrum.
