Abstract

The utility model relates to an air conditioner for buses. The utility model is composed of an engine, a water tank, a condenser, a compressor, a belt pulley, a universal drive shaft, a flow diversion head, a filter, a liquid storage device, a fan, a pipe, valves and a machine frame. The engine, the water tank, a muffler, the condenser, the liquid storage device and a repair hand valve are arranged on one side of the machine frame. The filter, the compressor, an evaporator, an expansion valve and an air cleaner are arranged on the other side of the machine frame. The cold and the heat are obviously separated, the condenser with large area is not needed, and the better refrigeration effect is achieved. The utility model has the characteristics of reasonable design, simple structure, compactness, firmness, good vibration prevention and leakage prevention, little energy consumption, large refrigerating capacity, low noise, etc. The interior of the utility model is provided with a full automatic protective device. When the water temperature is risen to 95 DEG C, the engine oil is less, or the lubricating system is failure, the cooling medium is less, or the pressure is super-high, the utility model automatically stops.

Description

The bus air conditioner machine

The utility model belongs to a kind of bus air conditioner machine.

At present, domestic existing many import bus air conditioner machines, similar between them, different with the first generation bus air conditioner machine of domestic production, compressor and driving engine are contained under the car, and refrigeration system is contained on the roof entirely, maintenance is convenient inadequately like this, be subject to directly photograph of the sun, the easy explosion of the pipeline of car causes the not leakage in Lyons, contaminated environment, and refrigeration is undesirable, and it is fast inadequately to dispel the heat, the rectification head, the electronics fan is fragile, even make engine overload, temperature rises, quits work, and patent 97210568.9 bus air conditioner machines, patent 98233965.8 bus air conditioner machines, structures such as patent 99235127.8 bus air conditioner machines are complicated, also the end can solve above-mentioned heat dissipation problem, the manufacturing cost height, benefit is low, should not promote the use of.

The purpose of this utility model provides a kind of bus air conditioner machine, put integral type and use the 134R refrigerant at the end, the structure principal feature is cold and hot clearly demarcated, ad hoc meter assembling becoming driving engine, water tank, noise silencer, condenser, liquid storage device, maintenance hand valve are on one side, mainly utilize the large-scale fan of condenser, the diffusion of driving engine and noise silencer temperature, reduce the temperature below the compartment, improve the refrigeration in the compartment.Filter, compressor, evaporator, expansion valve, airfilter are contained in another side, such structure can make evaporator not be subjected to the influence of any external temperature, keep good refrigeration, the temperature of getting back to compressor is low, so rejected heat are not high, and more stable, do not need very large-area condenser, reach refrigeration preferably equally.

The utility model is by driving engine, water tank, condenser, compressor, belt pulley, universal drive shaft, shunt head, filter, liquid storage device, fan, pipe, valve and frame are formed, two lattice about the frame (1) of band mounting hole is divided into, left side lattice are equipped with water tank (2), driving engine (3), condenser (4), liquid storage device (5), noise silencer (6), fan (7) and air pipe (8) are housed on the driving engine, air pipe (8) leads to outside the car, fan (9) is contained on the fan shaft bearing (10), fan shaft bearing (10) and belt pulley (11), adjusting knurl (12) links, adjusting knurl (12) and belt pulley A, B, C, adjusting knurl (13), belt pulley (14), automatically regulating wheel (15) links, belt pulley (14) links with supply ventilating fan (16), automatically regulating wheel (15) links with universal drive shaft (17), right lattice are equipped with device for drying and filtering (18), compressor (19), airfilter (20), evaporator (21), shunt head (22), expansion valve (23), high pressure hand valve (24) is housed on the compressor (19), low pressure hand valve (25), high-low pressure internally piloted valve (26), low-voltage tube (27), high-pressure pipe (28), maintenance hand valve (29) is housed on the connection pipe of liquid storage device (5) and device for drying and filtering (18), between A wheel and C wheel main bearing seat (30) is arranged, airfilter (20) is equipped with air pipe (31), and air pipe (31) links with the compartment.

The utility model is reasonable in design, and is simple in structure, and firmly compact, shockproof leakproof is good especially, and it is big to have the few refrigerating capacity of power consumption, and noise is low.In be provided with full-automatic protection device, if water temperature is elevated to 95 ℃, the few or lubricating system of machine oil has fault, the few and pressure superelevation of refrigerant all can auto-stop, cold and hot clearly.

Description of drawings:

Fig. 1 is the utility model structural representation.

In the utility model, except that frame can process with steel, all the other other parts all can be bought, as shown in Figure 1 after the assembling, integral installation is in the motorcoach bottom, select the electromagnetic clutch type compressor for use, working medium is used the 134R refrigerant, it is convenient to buy, and maintenance cost is low, the ad hoc meter assembling becoming of this machine driving engine, water tank, noise silencer, condenser, liquid storage device, maintenance hand valve is on one side, mainly utilize the large-scale fan of condenser, the temperature of driving engine and noise silencer diffusion, reduce the temperature below the compartment, improve the refrigeration in the compartment, and with filter, compressor, evaporator, the valve that rises of splashing, airfilter is contained in another side, such structure can make evaporator not be subjected to the influence of any external temperature, keeps good refrigeration, and the temperature of getting back to compressor is low, so rejected heat are not high, and more stable, do not need very large-area condenser, can reach refrigeration preferably equally.Loading onto ice plants, mix power supply, pass through universal drive shaft by driving engine, make compressor operating, compressor leads to condenser from high pressure hand valve through high-pressure pipe, and driving engine is by belt pulley A, B, adjusting knurl drives fan and rotates, and driving engine is by belt pulley A simultaneously, C, adjusting knurl drives blower fan and rotates, make the condenser heat radiation after, be communicated with liquid storage device, be communicated with maintenance hand valve and device for drying and filtering by pipeline again, expansion valve, shunt head is diverted to evaporator by shunt head, and cold air is by the return pipe of evaporator, through low pressure hand valve, arrive compressor again, in air pipe enters passenger cart, just finished whole process of refrigerastion.
