The specific embodiment
Below in conjunction with drawings and the specific embodiments structure of the present utility model and beneficial effect are elaborated.
With reference to shown in Figure 3, a kind of novel bus's special purpose vehicle air-conditioning system provided by the utility model, it comprises two groups of refrigeration systems, these two groups of refrigeration systems are mutually fully independently, and only electric control circuit is shared, thereby can realize using same control panel to control, simplified operation sequence, easy to operate, quick, and can open one group or two groups of refrigeration systems as required, select versatile and flexible.
Please refer to shown in Figure 4 again, it is the structure connection diagram of each refrigeration system in the utility model, the high-pressure side of vehicle-mounted compressor 1 is by a high-pressure switch 4 and a check valve 6, the high-pressure side of city's electric compressor 2 all is connected to the input of condenser 8 by another high-pressure switch 3 and another check valve 7, connect reservoir 10 more successively, stop valve 11, filter 12, liquid-sighting glass 13, magnetic valve 14, expansion valve 15, evaporimeter 16 and gas-liquid separator 18, be connected to vehicle-mounted compressor 1 and city's electric compressor 2 by low pressure switch 5, and condenser 8 places are provided with some condensation fans 9, and evaporimeter 16 places are provided with some evaporation fans 17 (check valve 6 herein, 7 can be triple valve, magnetic valve or reversal valve).Certainly, the utility model also can include temperature controller (probe) in system pipeline, alternating current-direct current vertoro, wire harness, control panel, electric-controlled box, the car, defrosting temperature controller (probe), cold-producing medium and inversion changing frequency speed regulator (can select) etc., because this is known configurations, and irrelevant with technology contents of the present utility model, do not repeat them here.
During present embodiment work, when special purpose vehicle is in the transport condition, this moment, the automobile sustainer was in running order, the automobile sustainer can be driven vehicle-mounted compressor 1 and the running of 24V generator (not shown) by belt, the effect of this 24V generator is to be the blower fan and the power supply of other electrical equipment control components and parts of air-conditioning when driving, city's electric compressor 2 in this group refrigeration system separates by check valve 7 and high-pressure section at this moment, prevents to reduce because of the compressor internal leakage refrigerating efficiency of refrigeration system; For vehicle-mounted compressor 1, it is compressed into high temperature and high pressure gas suck the low-temperature low-pressure refrigerant steam from evaporimeter 16 after, enters condenser 8 through check valve 6.The high-temperature high-pressure refrigerant steam is cooled in condenser 8 and condenses into normal temperature high voltage liquid, and under the effect of condensation fan 9, cold-producing medium is transformed into the flowed through air of condenser 8 fins of the heat that produces the liquid phase-change process from gaseous state and takes away.Liquid refrigerant continues to flow, and through reservoir 10, stop valve 11, filter 12, liquid-sighting glass 13, magnetic valve 14, enters expansion valve 15, enters evaporimeter 16 after expansion valve 15 dams step-down.In evaporimeter 16, the low-temp low-pressure liquid refrigerant absorbs airborne heat and undergoes phase transition the cold-producing medium that becomes gaseous state, after gas-liquid separator 18 separates, by vehicle-mounted compressor 1 suction of the cold-producing medium of gaseous state is entered and to carry out next one in the vehicle-mounted compressor 1 and circulate, simultaneously under the effect of evaporation fan 17, return air and outdoor new distinguished and admirable through evaporimeter 16 fins in the car is sent into after drying by cooling and is realized in the compartment freezing.By the continuous running of vehicle-mounted compressor 1, cold-producing medium is constantly circulation in system, has so just produced the continuous cooling effect.
When the engine on the special purpose vehicle is not worked, can be by city's electric compressor 2 be connected extraneous AC220V/50Hz mains supply or gasoline engine generator or storage battery group (also can use other power source or power supply), be to adopt the AC-to-DC vertoro to obtain the DC24V direct current herein, be air-conditioning draught fan and other control components and parts power supply, switch to the air conditioner group system running refrigeration that city's electric compressor 2 is connected thereby make; City's electric compressor 2 cooperates running similar with the operation principle of aforementioned vehicle-mounted compressor 1 with the air-conditioning unit, does not give unnecessary details at this.
It is pointed out that and work as special purpose vehicle in the process of moving, when temperature reaches setting range, can disconnect vehicle-mounted compressor 1 and condensation fan 9 by the control panel (not shown), this moment, evaporation fan 17 was still worked, and air-conditioning system changes ventilation state over to; When temperature reached setting range or only opens evaporation fan 17 when stopping, air-conditioning system was a ventilation state.
In addition, the utility model also can further be optimized, as reducing external noise in the car by the area of dissipation that increases two devices, the methods such as return air inlet area, reduction circulation wind speed that strengthen; Evaporation fan 17 is adopted the herringbone impeller, to reduce internal car noise; Also can under the non-engine behavior of special purpose vehicle, adopt the inversion changing frequency speed adjusting technique,, improve the Energy Efficiency Ratio of refrigeration system to cut down the consumption of energy.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
