Abstract
The utility model discloses a motor bus is with two air conditioning system, including air condition compressor, condenser and stock solution drier -filter, still include preceding temperature sensing package, preceding evaporimeter and control the preceding expansion valve and the preceding solenoid valve of preceding evaporimeter, still including back temperature sensing package, finisher and control the afterexpansion valve and the back solenoid valve of finisher, the entry of pipe connection condenser is passed through in air condition compressor's export, the exit linkage stock solution drier -filter's of condenser entry, stock solution drier -filter's exit is provided with a tee bend pipeline, the entry end of evaporimeter and finisher before connecting respectively, the utility model discloses be provided with two evaporimeters to with the control of solitary solenoid valve, so two evaporimeters can set up both ends around the motor bus respectively, making the temperature of whole passenger train more even respectively, also having avoided simultaneously in order to make all passengers all be satisfied with, it is extravagant to open the electric power that leads to the fact greatly with the air conditioner.
Description
Technical field
The utility model relates to on-board air conditioner, is specifically related to the two air-conditioning system of a kind of motor bus.
Background technology
The difference of motor bus and general-utility car is, motor bus volume is large, gets multiple point for measuring temperature in car, and measured temperature is general not identical.If use independent aircondition, then air-conditioning cold wind cannot uniform transmission to full car, from the air outlet close to compressor of air conditioner, passenger feels very cold, and from the air outlet away from compressor of air conditioner, passenger but can feel sultryyer, and as the summer in sweltering heat, the general temperature of first half section of vehicle head part and car is higher.And if all reach lower temperature, the second half section of car can be colder, and air-conditioning need expend more electric power.Two air-conditionings can also be filled in addition, but need like this to drop into larger financial cost.
Utility model content
In order to solve the deficiencies in the prior art, the utility model discloses the two air-conditioning system of a kind of motor bus.
The technical solution of the utility model is as follows:
The two air-conditioning system of a kind of motor bus, comprises compressor of air conditioner, condenser and liquid storage device for drying and filtering, it is characterized in that: also comprise front temperature-sensitive bag, front evaporator and control the front expansion valve of described front evaporator and front magnetic valve; Also comprise rear temperature-sensitive bag, finisher and control rear expansion valve and the rear electromagnetic valve of described finisher; The outlet of described compressor of air conditioner connects the entrance of condenser by pipeline, the outlet of described condenser connects the entrance of liquid storage device for drying and filtering, the exit of described liquid storage device for drying and filtering is provided with a three-way pipeline, connects the arrival end of front evaporator and finisher respectively; Be provided with front magnetic valve between liquid storage dryer and front evaporator, between liquid storage dryer and finisher, be provided with rear electromagnetic valve; The connecting pipe of described front temperature-sensitive bag and rear temperature-sensitive bag is in parallel with front evaporator and finisher respectively; Temperature-sensitive bag before described front expansion valve controls, temperature-sensitive bag after rear expansion valve controls.
Advantageous Effects of the present utility model is:
The utility model is provided with two evaporimeters, two temperature-sensitive bags, and control with independent magnetic valve and expansion valve respectively, so two evaporimeters can be separately positioned on the rear and front end of motor bus, make the temperature of whole passenger vehicle more even, effectively prevent the non-uniform temperature caused because car body is excessive, passenger's body sense difference is excessive, also avoiding to make all passengers all satisfaction simultaneously, air-conditioning must be opened the power wastage caused greatly.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Fig. 1 is schematic diagram of the present utility model, and the utility model comprises compressor of air conditioner 1, condenser 2 and liquid storage device for drying and filtering 11, also comprises front temperature-sensitive bag 10, front evaporator 7 and controls front expansion valve 8 and the front magnetic valve 9 of front evaporator 7; Also comprise rear temperature-sensitive bag 6, finisher 3 and control rear expansion valve 4 and the rear electromagnetic valve 5 of finisher 3.
The outlet of compressor of air conditioner 1 connects the entrance of condenser 2 by pipeline, the outlet of condenser 2 connects the entrance of liquid storage device for drying and filtering 11, the exit of liquid storage device for drying and filtering 11 is provided with a three-way pipeline, connects the arrival end of front evaporator 7 and finisher 3 respectively; Be provided with front magnetic valve 9 between liquid storage dryer 11 and front evaporator 7, between liquid storage dryer 11 and finisher 3, be provided with rear electromagnetic valve 4; The connecting pipe of front temperature-sensitive bag 10 and rear temperature-sensitive bag 6 is in parallel with front evaporator 7 and finisher 3 respectively; Front expansion valve 8 controls front temperature-sensitive bag 10, and rear expansion valve 4 controls rear temperature-sensitive bag 6.
After air-conditioning energising, the low-pressure steam of refrigeration system inner refrigerant is sucked by compressor of air conditioner 1 and drains into condenser 2 after boil down to high temperature and high pressure steam.The outdoor air that aerofoil fan sucks simultaneously flows through condenser, takes away cold-producing medium liberated heat, makes high-temperature high-pressure refrigerant steam condensation be highly pressurised liquid.Highly pressurised liquid, after liquid storage device for drying and filtering 11, enters front evaporator 7 and finisher 3 simultaneously, and evaporates (swollen apneusis heat) under corresponding low pressure, draws heat around.And the air turned cold after heat release is sent in car.In car like this, air constantly circulates, and reaches the object reducing temperature.Heat principle similar, just contrary with some steps of refrigeration principle.
When freezing, because the utility model is provided with front evaporator 7 and finisher 3 simultaneously, so can the heat of uniform pickup passenger vehicle front and rear, make passenger vehicle integrally, temperature declines more even, and passenger vehicle internal temperature is suitable for, and the sense of passenger's body is more comfortable.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
