42 air inlet pipe and blast pipe is in parallel, and is connected with gas balance pipe and oil balance tube between two compressors 42.It is totally-enclosed
Scroll compressor in terms of anti-vibration, anti-liquid hammer and frequent starting have excellent performance, but also with noise it is low,
The characteristics of vibrating small, efficiency high and long lifespan.
Two condensers 40 often in set refrigerating and heating systems are parallel with one another, and the exhaust outlet of compressor set passes through pipeline simultaneously
Into two condensers 40, the outlet of each condenser 40 connects an expansion valve, and the outlet of expansion valve connects an evaporator
37, the outlet of two evaporators 37 is connected in parallel to be connected with the air inlet of compressor set, forms the refrigerating circuit of complete set.
Often set refrigerating and heating systems are individually equipped with a controller (not shown), and two controllers are separately mounted to two
The inside of individual indoor chamber 7, controller controls two sets of refrigerating and heating systems each to work independently, also by many between two controllers
Core shielded cable carries out communication and realizes the interconnection started with failure, facilitates repair and maintenance.In the present embodiment, controller is passed through solid
The structures such as fixed rack (not shown) install the top of chamber 7 indoors, and in return air region, the region heat dissipation environment is good, can
Cooled using return air to controller, and then can effectively extend the working life of electrical equipment in controller.
In the present embodiment, installed in the bottom wall of air-conditioner set 4 close to return air inlet position for the electricity with in-car cable connection
Air connector and Communication Programming interface, correspond to control loop and major loop, control loop and major loop are connected up out from in-car respectively
The wire harness come is entered inside air-conditioner set 4 by connector, and electrical cnnector and Communication Programming interface are arranged on indent
In window, pass, malfunction indicator lamp and SR etc. are turned on by there also is provided ten thousand in window.This bottom in air-conditioner set 4
Portion sets the design of connecting interface, is highly convenient for operation and maintenance after the entrucking of air-conditioner set 4, can be set using portable test
It is standby air-conditioning system to be communicated and failure is downloaded etc., facilitate troubleshooting, realize that the Air-conditioner design of electromechanical integration is required.
Air-conditioner set 4 carries out multi-stage refrigerating capacity adjustment automatically, and controller is according to the return air temperature and automatic warm collected
Degree controlling curve is compared, and air-conditioner set is cut between half cold operating mode, complete cold operating mode, ventilation operating mode and heating condition
Change, realize in-car thermostatic control and protect the fresh of in-car air, can also preferably protect compressor, and reach energy saving
Purpose.
Wherein, ventilation operating mode：Only have evaporation fan 38 to work in air-conditioner set 4, after fresh air is mixed with return air, through filter
Filtering, is then delivered to treated air by the opening on air outlet 16 and steel structure of car body 23 by evaporation fan 38
In wind air channel 22, then it is sent in guest room by in-car air outlet 12 and in-car air outlet 36.
Half cold operating mode：Only a set of refrigeration system work, that is, have two evaporation fans 38, a condensation fan 41 and Liang Tai
Compressor 42 works, after fresh air is mixed with return air, completes refrigeration cool-down by evaporator 37, then will be passed through by evaporation fan 38
The air of processing is sent in supply air duct 22.
Complete cold operating mode：Two sets of refrigeration systems all work, four evaporation fans 38, two condensation fans 41, four compressions
Machine 42 is worked, after fresh air is mixed with return air, and refrigeration cool-down is completed by evaporator 37, then will be passed through by evaporation fan 38
The air of reason is sent in supply air duct 22.
Heating condition：Four evaporation fans 38 and four electric heaters 39 are worked, and fresh air is mixed with return air, passes through electrical heating
After device 39 is heated, it is sent to by evaporation fan 38 in supply air duct 22, to carrying out temperature control and air adjustment in guest room.This implementation
In example, by PLC according to temperature control curve, PWM is exported by PLC output end and controls turning on and off for solid-state relay,
PWM produces the pulse output of a change in duty cycle and cycle fixation, realizes and carries out 0- to the heating capacity of electric heater 39
100% step-less adjustment.
As shown in figure 5, the case top in each indoor chamber 7 is provided with two maintenance door (figures that can be flipped up opening
In do not indicate), maintenance door is connected by folding 45 with middle crossbeam 46, and the active edges of maintenance door pass through lock structure and housing
6 are fixedly connected, it is to avoid opened in vehicle operation, and the setting of maintenance door facilitates operating personnel's maintenance repair and maintenance.
The controller of air-conditioner set realizes network communication function by RS485 and drivers' cab monitoring system, and controller can be with
The running state information and fault message of air-conditioner set 4 are uploaded to drivers' cab monitoring system.Realized by network communication circuit
To the long-distance centralized control of air-conditioner set, without by the machine control, operating personnel can realize air conditioner in drivers' cab operating desk
The start and stop of group, the running status of remote monitoring air conditioner.When one accessory power supply failure of vehicle, vehicle is to air-conditioner set
4 send signal, and the automatic deloading of air-conditioner set 4 runs half chill formula, and when accessory power supply recovers normal, air-conditioner set 4 is just automatic
It is converted into normal refrigeration mode.
As shown in Figure 6 and Figure 7, inner trim panels are installed in the inner side of car body 1, it is interior to beautify the environment by bus in guest room
