Description
Technical field
The utility model relates to medium bus air-conditioning and compression-type refrigeration device.
Background technology
The air-conditioning that uses on the current medium bus is a cover compression-type refrigeration mechanism, is the collocation form of an evaporator assembly and a condenser assembly.Because interior space is bigger, this single cold collocation form that steams, in medium bus, normally evaporator assembly is arranged on rear vehicle, by the air channel about the car inner top cold air is guided in the car because the operator's compartment front is transparent Windshield, sunshine with direct irradiation in operator's compartment, the operator's compartment bottom is the driving engine of hot operation, so will make the temperature drift of operator's compartment, make the vehicle interior temperature skewness, form rear portion cold in the car and anterior heat; Single simultaneously cooling efficient of steaming car load also shows lower.In addition, the evaporator assembly in the above-mentioned air-conditioning only uses as refrigeration device, only solve the interior cooling problem of car in hot day, and in severe winter, it is very cold that passenger and driver feel; Owing to use air-conditioning, take sealing in the car, the occupant is many, and air quality is poor, have to take at roof relevant apparatus installation air suctiton ventilator to be set in addition and supply new wind (car outer air).This situation of air-conditioning makes the comfort level of this vehicle relatively poor on the current medium bus, and other establishes aeration device also increases the cost that car load is made.
Summary of the invention:
The purpose of the utility model be to solve the medium bus air-conditioning can only singlely lower the temperature, and cooling is uneven and inefficient problem, provides a kind of two medium bus air-conditioning that steams new wind of a cold belt and heating arrangement, to improve the comfort level of medium bus.
The technical scheme that realizes above-mentioned purpose is: design an energy at the anterior evaporator assembly that is provided with of car, with this evaporator assembly and the existing evaporator assembly that now is arranged on the car rear portion mutually and connect into air conditioner loop, constitute two cold collocation of steaming, and, aeration device that communicates with the car outer air and the heating arrangement that communicates with the engine water-cooling cycling mechanism are set on newly-designed front evaporator device assembly.
The concrete structure of new design part is, has a front evaporator device assembly shell that communicates and link to each other and form by spiral case and evaporator shell, the aeration device that blowing engine is set on the spiral case and is interlinked to the outside with car, be provided with in the evaporator shell and be connected in the expansion core of air conditioner loop and the heating arrangement that is connected with the automotive engine water-cooling circulating system, the air door and the driving lever thereof in conversion cold wind, hot blast, new wind air channel are set in aeration device and evaporator assembly, and air outlet is located on the housing of rear end, described air channel.
By the medium bus air-conditioning that technique scheme constituted, when needs freeze, control circuit makes the blowing engine work of compressor and forward and backward evaporator assembly, the forward and backward evaporator assembly that is in parallel is to lower the temperature in the car as two refrigeration sources, the finisher assembly only plays refrigeration and worked as in the past, front evaporator device assembly, need to handle it and go up driving lever and make air door open cold air duct and close hot-air channel, forward and backward evaporator assembly makes jointly and forms the heat exchange cycle that freezes in the car; When needs heat, control circuit cuts out compressor, only start front evaporator device assembly blowing engine, driving lever on the manipulation front evaporator device assembly makes air door open hot-air channel and cuts out cold air duct, the calorific effect that the cooling water expansion tank of automotive engine is produced through the heating arrangement in the front evaporator device assembly time, under the effect of blowing engine, in car, produce hot air circulation; When needs are imported fresh air in car, control circuit is opened the air door of the aeration device on the front evaporator device assembly, start the blowing engine on the front evaporator device assembly simultaneously, the car outer air through aeration device again through the cold wind air channel or the hot blast air channel form outer circulation into the car, if close the air door of aeration device, then form circulation in the car; The suction of new wind can be carried out separately, also can be interrupted in refrigeration or heating and use.
The utility model has the advantages that:
1. former and later two refrigeration sources all are greatly improved the degree of uniformity and the intensity of cooling in the car.
2. can realize freezing, heat, sending the multiple function of new wind on request,, improve the class of medium bus for the passenger provides comfortable environment inside car.
3. though be multi-functional air conditioner, its structure is simple, compact, cold wind, hot blast, the new shared blowing engine of wind, three air channels are comprehensively shared, make the manufacturing cost of air-conditioning and use cost low.
4. heating arrangement utilizes the water-cooling circulating system of driving engine, and heating is a thermal source with the cooling water expansion tank, not only rationally but also energy-conservation, and also effective, also be beneficial to simplified structure.
5. the device collection that will realize fresh air supply and heating, refrigeration is an one, does not need to establish air suctiton ventilator and relevant apparatus at roof in addition, thereby has reduced the cost of car load.
