Abstract
The utility model discloses a kind of refrigerator car refrigeration system with sequential startup, including the refrigerator car refrigeration system being made up of vehicle-mounted compressor, oil eliminator, condenser, reservoir, device for drying and filtering, vaporizer, the high pressure admission mouth of oil eliminator connects with vehicle-mounted compressor high-pressure exhaust；The outlet of oil eliminator is leaded up to stop valve and is connected with condenser inlet, separately leads up to defrosting valve, expansion valve and connects with vehicle-mounted compressor return air mouth with vaporizer；Defrosting valve control input, stop valve control input, condensation fan controller control input and evaporation fan controller control input and are connected with the output control terminal of Programmable Logic Controller respectively, and the input at Programmable Logic Controller controls end connection temperature controller.This utility model advantage is when refrigerator car refrigeration system starts, and the electrical equipment that power is big, starting current is big successively starts to avoid affecting other electrical equipments worked of vehicle.
Description
Technical field
This utility model relates to refrigerator car refrigeration system, especially relates to have the refrigerator car refrigeration system that sequential starts.
Background technology
Refrigerator car is widely used in transport frozen or fresh-keeping goods, is equipped with the special transport automobile of refrigeration unit, such as freezing
The transport of food, milk product, vegetable and fruit, vaccine medicine etc..Owing to immediate current during refrigerating equipment startup work is relatively big, and
The DC source accessed also is the electromotor by vehicle chassis and accumulator offer, and man of Railway Car Plant only considers that car load dispatches from the factory
Time total electricity consumption electrical power, not accounting for client's later stage reequips situation；Therefore will when client reequips other electrical equipments of interpolation
Cause electric power excessive and affect using effect and even result in the circuit of vehicle and be damaged.
Summary of the invention
This utility model purpose is that providing a kind of has the refrigerator car refrigeration system that sequential starts.
For achieving the above object, this utility model takes following technical proposals:
Described in the utility model have sequential start refrigerator car refrigeration system, including by vehicle-mounted compressor, oil eliminator,
The refrigerator car refrigeration system that condenser, reservoir, device for drying and filtering, vaporizer are constituted, the high pressure admission mouth of described oil eliminator
Connect with vehicle-mounted compressor high-pressure exhaust；The outlet of described oil eliminator leads up to stop valve with described condenser inlet even
Logical, separately leading up to defrosting valve, expansion valve connects with vehicle-mounted compressor return air mouth with vaporizer；Described defrosting valve controls input
End, stop valve control input, condensation fan controller control input and evaporation fan controller control input respectively with
The output control terminal of Programmable Logic Controller connects, and the input at described Programmable Logic Controller controls end connection temperature controller.
This utility model advantage is to control cold preservation unit by the sequential set by temperature controller and Programmable Logic Controller
Start.When refrigerator car refrigeration system starts, the electrical equipment that power is big, starting current is big successively starts to avoid affecting car
Other electrical equipments worked, more effectively prevent the moment that refrigeration unit large power-consuming equipment starts simultaneously,
Causing vehicle electrical equipment load reduction, voltage to raise makes vehicle circuit, generator set controller chip by impact failure.
Accompanying drawing explanation
Fig. 1 is hydraulic system structure schematic diagram of the present utility model.
Fig. 2 is electrical control system structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, 2, described in the utility model have the refrigerator car refrigeration system that sequential starts, including by vehicle-mounted compression
The refrigerator car refrigeration system that machine 1, oil eliminator 2, condenser 3, reservoir 4, device for drying and filtering 5, vaporizer 6 are constituted, described oil
The high pressure admission mouth of separator 2 connects with vehicle-mounted compressor 1 high-pressure exhaust；The outlet of described oil eliminator 2 lead up to cut
Only valve 7 and described condenser 3 inlet communication, separately leads up to defrosting valve 8, expansion valve 9 and vaporizer 6 and vehicle-mounted compressor 1 time
QI KOU connects；Described defrosting valve controls input 10, stop valve controls input 11, condensation fan controller controls input 12
Control the input 13 output control terminal respectively with Programmable Logic Controller 14 with evaporation fan controller to be connected, described able to programme
The input of controller 14 controls end connection temperature controller 15.
When this utility model refrigeration unit starts refrigeration, first Programmable Logic Controller 14 starts stop valve 7, defrosting valve 8 and
Condensation fan, closes defrosting valve 8, the vehicle-mounted compressor of subsequent start-up 1, finally starts evaporation fan after the time of delay adjustments.
When refrigeration unit is shut down, Programmable Logic Controller 14 is first shut off vehicle-mounted compressor 1, is then switched off condensation fan, cuts
Only valve 7, finally cuts out evaporation fan.
