Description
Technical field
The utility model relates to air conditioning system for vehicle, is specifically related to a kind of air-conditioning system being adapted to low speed tractor.
Background technology
Along with industrialized deep, the division that market is applied automobile is more careful, and low speed tractor is widely used in the operating mode of work pattern in the fields such as harbour with features such as its high pulling torque, low speed, good economy performance.But because current low speed tractor still carries out adaptive improvement on traditional on-highway tractor basis, this just causes vehicle in use can not well adapt to low cruise operating mode.Such as, the speed of a motor vehicle of road vehicle is substantially all run in high speed, and car air-conditioner can to cool air-conditioning condenser by air flowing thus ensure the refrigeration of air-conditioning.The effect of condenser is the high-temperature high-pressure refrigerant gas that compressor of air conditioner is discharged, and is distributed heat in car outer air, thus makes the condensation of refrigerant of HTHP become the highly pressurised liquid of higher temperature, realize the refrigeration work of air-conditioning further by condenser.But low speed tractor runs for a long time under low speed or idle conditions, the flow velocity of this kind of operating mode air draught is very low can not well dispel the heat to air-conditioning condenser, so low speed tractor is in use substantially all poor at reflection air conditioner refrigeration effect at present.
Utility model content
For solving the problem, the utility model provides a kind of low speed tractor air-conditioning system of good refrigeration effect.
The technical solution of the utility model is: a kind of air-conditioning system being adapted to low speed tractor, comprise main condenser, compressor of air conditioner, evaporimeter, compressor of air conditioner sucks cold-producing medium from evaporimeter, and cold-producing medium is entered main condenser, it is characterized in that, also comprise air-conditioning radiator cooler, air-conditioning radiator cooler comprises auxiliary condenser and blower fan, cold-producing medium from main condenser absorption refrigeration agent, and is entered evaporimeter by auxiliary condenser, and blower fan is arranged on auxiliary condenser.
Preferably, air-conditioning radiator cooler is arranged on the wherein side of under-cab vehicle frame both sides.
Preferably, blower fan is electromagnetic fan.
Preferably, the operating switch of blower fan is arranged in driver's cabin.
Preferably, the power supply of blower fan is connected on battery.
Preferably, auxiliary condenser is also installed the wind shelling cover agreed with blower fan.
Beneficial effect: a kind of air-conditioning system being adapted to low speed tractor that the utility model provides, compared with prior art, original air conditioning system for vehicle adds air-conditioning radiator cooler, and the operating switch of blower fan is arranged in driver's cabin, the long-time low speed of tractor or idle time, driver opens the operating switch of blower fan in driver's cabin, and blower fan starts air draught work, forced heat radiation is carried out to auxiliary condenser, improves auxiliary condenser radiating effect; The wind shelling cover agreed with blower fan strengthens the air draught effect of blower fan, can strengthen the radiating effect of auxiliary condenser further.The utility model is little to existing air conditioning system for vehicle change amount, and repacking is convenient, and the utility model is easy to operate simultaneously, effectively can improve the refrigeration of car air-conditioner under tractor low speed or idling operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail.
As shown in Figure 1, air-conditioning radiator cooler in the compressor of air conditioner 7 be adapted to an air-conditioning system for low speed tractor, comprise main condenser 9, being connected by pipeline 8 with main condenser 9, the evaporimeter 5 be connected by pipeline 6 with compressor of air conditioner 7, dotted line frame.Evaporimeter 5 is integrated with throttling arrangement.Air-conditioning radiator cooler comprises auxiliary condenser 1, auxiliary condenser 1 is connected with evaporimeter 5 by pipeline 4, be connected with main condenser 9 by pipeline 10, the wind shelling cover 2 auxiliary condenser 1 installed blower fan 3 and agree with blower fan 3, blower fan 3 is electromagnetic fans, and the operating switch of blower fan 3 is arranged in driver's cabin.Air-conditioning radiator cooler is arranged on the wherein side of under-cab vehicle frame both sides.During air-conditioning system work, compressor of air conditioner 7 sucks cold-producing medium from evaporimeter 5, and cold-producing medium is entered main condenser 9, and cold-producing medium is entered auxiliary condenser 1 by main condenser 9 simultaneously, and cold-producing medium is entered evaporimeter 5 by auxiliary refrigerator 1.
When tractor middling speed is run, air and vehicle relative velocity can meet air-conditioning cooling requirement, and blower fan 3 is inoperative, and main condenser 9 and auxiliary condenser 1 are cooled air-conditioning by the flowing of medium speed's air.
When the long-time low speed of tractor or idle time, driver opens blower fan 3 operating switch in driver's cabin, blower fan 3 power supply is connected and is started air draught work, carries out forced heat radiation to auxiliary condenser 1, improves the air conditioner refrigeration effect of tractor under low speed or idling operation.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
