Description
Technical field
The present invention relates to A/C evaporator field, specifically a kind of evaporator using for air with heating fuel oil.
Background technique
The extraordinary mating special air-conditioning units of move vehicle, special air-conditioning units have the function of refrigeration, heating etc., are in-vehicle device and personnel
Good warm and humid environment is provided.Since move vehicle is motor-driven, characteristic after whole day, and the matched electrical power generators output work of special vehicle
Rate will not be very big, limits the electric power of special air-conditioning units.
Extraordinary move vehicle is when High-cold regions use (design requirement reaches -45 DEG C), to guarantee higher temperature requirement in cabin,
The heating capacity of special vehicle demand is very big, and traditional heat pump heating heating effect under lower than -7 DEG C environment is poor, is not able to satisfy vehicle
Temperature, which is adjusted, to be required；For the low-temperature heating requirement for guaranteeing High-cold regions, general special air-conditioning units are made using electric heating tube (or PTC)
Heat, such mode heat efficiency is low (efficiency about 0.8), and when heating capacity demand is big, electric power is also very big, extraordinary locomotive
So big power supply can not be provided at all.
The object of the present invention is to provide a kind of evaporator using for air with heating fuel oil for summary of the invention, existing to solve
There is technology special type move vehicle the air conditioner low temperature heating of High-cold regions the problem of.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of evaporator using for air with heating fuel oil, it is characterised in that: including evaporator body, fuel heater, water
Case, water pump set cooling liquid flowing channel and refrigerant flow path in evaporator body, and evaporator body is configured with evaporation fan, evaporation
The intrinsic cooling liquid flowing channel outlet end of device is sequentially connected after fuel heater, water tank, water pump again tieback extremely by hot water pipeline
Cooling liquid flowing channel input end constitutes coolant liquid circulation loop, and the refrigerant flow path import and export end in evaporator body passes through refrigeration
Agent pipeline and external refrigerant source connect and compose refrigerant circulation loop.
A kind of evaporator using for air with heating fuel oil, it is characterised in that: between the water tank and water pump
Hot water pipeline connection access have flow switch.
A kind of evaporator using for air with heating fuel oil, it is characterised in that: the fuel heater installs additional
The admission line and exhaust pipe for having and being connected to inside fuel heater, exhaust pipe add silencing apparatus.
A kind of evaporator using for air with heating fuel oil, it is characterised in that: the system of the evaporator body
Cold and heating shares evaporation fan.
When heat-exchange system of the present invention heats, the coolant liquid in hot water pipeline flows into water tank after fuel heater heats,
Coolant liquid in water tank successively flows through evaporator after flow switch and water pump, through evaporation fan forced-convection heat transfer to needs
Implement heating in the space of heating.
When refrigeration work of the present invention, the low-temperature low-pressure refrigerant liquid in refrigerant tubing flows through evaporator, through evaporating wind
Machine forced-convection heat transfer implements cooling to the space that cools down of needs, and refrigerant becomes low temperature low pressure gas through outer loop again at this time
It flows back in evaporator refrigerant pipeline, so circulation repeatedly, realizes refrigeration.
Hot water of the present invention by recycling connection evaporator on refrigeration system pipeline and heat-exchange system pipeline, in evaporator
Pipeline is integrated with refrigerant tubing, and refrigeration shares evaporation fan with heating, and low temperature system can be achieved in the heat exchange for passing through evaporator
Heat or high-temperature refrigeration.
Advantages of the present invention:
1) evaporator heat exchange effect, can substantially effectively be played；
2), system pipeline is simple, easily controllable；
3), use environment wide temperature range, heating effect is good in the environment of -45 DEG C；
4), regulative mode is simple, easy for installation, reliable for operation, at low cost, and failure rate is low, securely and reliably.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, a kind of evaporator using for air with heating fuel oil, includes evaporator body 1, evaporator sheet
Evaporation fan 8, refrigerant tubing 2 and the hot water pipeline 3 that body 1 configures, evaporator body 1 have been internally integrated refrigerant flow path and cold
But liquid stream road, wherein cooling liquid flowing channel is communicated with heat-exchange system by the circulation of hot water pipeline 3, and heat-exchange system includes in evaporator 1
The fuel heater 4 of the outlet connection of cooling liquid flowing channel, the water being connected between fuel heater 4 and the import of cooling liquid flowing channel
Case 5 is connected with flow switch 6 and water pump 7 in turn between water tank 5 and the import of cooling liquid flowing channel.Add in fuel heater 4 simultaneously
It puts into inside feed channel 9 and exhaust pipe 10, admission line 9 and exhaust pipe 10 and fuel heater 4 and is connected to, and exhaust pipe
Road installs silencing apparatus 11 additional.
When heat-exchange system exchanges heat, the coolant liquid in hot water pipeline 3 flows into water tank 5, water after the heating of fuel heater 4
Coolant liquid in case 5 successively flows through evaporator 1 after flow switch 6 and water pump 7, through evaporation fan Final 8 heat convection to need
The space implementation environment of temperature adjustment is wanted to control.
Specific work process is as follows:
When external environment temperature and evaporator return air temperature are relatively low, fuel heater 4, water pump 7 work, the heat in evaporator 1
Coolant liquid in waterpipe 3 enters water tank 5 after the heating of fuel heater 4, and the coolant liquid in water tank 5 successively passes through flow switch
6 and water pump 7 after flow through evaporator 1 heating implemented to the space heated of needs through evaporation fan Final 8 heat convection, then flow back to steaming
It sends out in device hot water pipeline 3, so circulation repeatedly, realizes heating.
When external environment temperature and evaporator return air temperature are relatively high, refrigeration work, the low-temp low-pressure in refrigerant tubing 2
Refrigerant flows through evaporator 1 and implements cooling to the space that needs cool down through evaporation fan Final 8 heat convection, then flows back to evaporator
In refrigerant tubing 2, so circulation repeatedly, realizes refrigeration.
The present invention can effectively disperse the calorific value of carrier in the case of a high temperature of generating heat, can be quick at low temperatures to carrier
Heating is applicable in wide temperature environment work, and energy conservation；
The configuration of the present invention is simple, reliable for operation while easy for installation, easily fabricated, at low cost, failure rate is low.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
