Description
Technical field
The utility model category heavy truck air-conditioning system.
Background technique
Currently, heavy truck air-conditioning system conventional arrangement is；One front-packed evaporator assembly and a mechanical commprssor and one
A motor compressor.Influenced by cab space, at present front-packed evaporator assembly it is main based on drive and the passenger side refrigeration or heating,
Air quantity and refrigerating capacity can not be provided for sleeping berth.Simultaneously when using Air conditioner on car, electrical compressor power is small, front-packed evaporator function
Rate is big.Cause Air conditioner on car air outlet temperature high, effect is poor.It is unable to satisfy better refrigeration demand.
Summary of the invention
The purpose of this utility model is to provide the heavy truck air-conditioning system of a kind of double-compressor and double evaporators, the air-conditioning systems
System provides cooling capacity for sleeping berth, meets user's need by the basis of traditional heavy truck air-conditioning, increasing an overhead type evaporator assembly
It asks.
The heavy truck air-conditioning system of double-compressor and double evaporators, including a mechanical commprssor, an electrodynamic type compression
Machine, a condenser assembly and a forward type evaporator, further include an overhead type evaporator, when parking, motor compressor
Operation is matched with overhead type evaporator；When driving, mechanical compressor is run simultaneously with front-packed evaporator, overhead type evaporator.
Overhead type evaporator is arranged in driver's cabin overhead box.
Overhead type evaporator includes: evaporator core, evaporation fan, solenoid valve, upper housing, lower case, air outlet, upper casing
Body, lower case are provided with evaporator core, and the outside of shell is equipped with evaporation fan, and the outside of shell is equipped with air outlet, on shell
It is also equipped with solenoid valve, solenoid valve is used to control the switch of overhead type evaporator, and evaporation fan evaporates wind using the small blower of single volute
The wind direction and evaporator core header axis of the air outlet of machine are arranged in parallel, and upper housing and lower case are all made of gradual change type section
Design.
The good effect of the utility model are as follows:
(1), for the utility model by adding an overhead type evaporator assembly, turner condition of being expert at, parking operating condition can be same
When for driver's cabin and sleeping berth provide refrigerating capacity, improve comfort；
(2), the stability of truck air conditioning, anti-caking can be improved by double steamings, double-compressor air-conditioning system in the utility model
Ice meets various weather conditions use demands；
(3) overhead type evaporator of the utility model, using evaporation fan wind direction at air outlet and evaporator core header
Axis parallel arrangement solves the problems, such as that X-direction narrow space, blower upper-lower casing use gradual change type section, solve evaporation
Device core surface wind speed uneven phenomenon；Not only space size is met, but also meets refrigeration demand.
Detailed description of the invention
Fig. 1 is the utility model driving operating condition operation figure；
Fig. 2 is the utility model parking operating condition operation figure；
Fig. 3 is overhead type evaporator structural schematic diagram；
Fig. 4 is overhead type evaporator cross-sectional view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Referring to Fig. 1-2: automobile in the process of moving, after currently emptying tune opening, such as needs top-mounted air conditioner also to open, then beats
The wind file switch on top-mounted air conditioner is opened, the solenoid valve 3 on overhead type evaporator is opened at this time, and top-mounted air conditioner is started to work；It is mechanical
Formula compressor gives forward type evaporator and overhead type evaporator cooling supply by condenser assembly simultaneously；When needing to close top-mounted air conditioner
When, wind file switch thereon need to be only closed, solenoid valve 3 is closed, and top-mounted air conditioner is closed, and mechanical commprssor passes through condenser at this time
Assembly only gives forward type evaporator cooling supply.Top-mounted air conditioner relies on the on and off of the solenoid valve 3 of overhead type evaporator, steams to top
Feed flow is controlled；Forward type evaporator controls compressor space by evaporator surface temperature；When parking, start electrodynamic type
Compressor gives overhead type evaporator assembly cooling supply by condenser assembly.
In Fig. 3-4: overhead type evaporator is arranged in driver's cabin overhead box, i.e. the passenger side crown.Overhead type evaporator assembly,
It include: evaporator core 1, evaporation fan 2, solenoid valve 3, upper housing 4, lower case 5, air outlet 6, in upper housing 4, lower case 5
Equipped with evaporator core 1, the outside of shell is equipped with evaporation fan 2, and the outside of shell is equipped with air outlet 6, is also equipped with electricity on shell
Magnet valve 3, solenoid valve 3 are used to control the switch of overhead type evaporator.Air outlet 6 is limited by Z-direction, X-direction space, evaporation fan
Using the small blower of single volute, blower Z-direction size: 120mm;X-direction size: 128mm;2 wind direction at air outlet of evaporation fan and steaming
1 header axis of device core parallel arrangement is sent out, solves the problems, such as X-direction narrow space.2 upper-lower casing of evaporation fan is using gradually
Variant section solves evaporator core surface wind speed uneven phenomenon.
The specific structure of other undocumented components in the utility model, is the prior art.The utility model passes through
It is additionally arranged an overhead type evaporator, it is big to solve heavy truck driver's cabin refrigeration space, but the problem that installation space is small.
