Accompanying drawing explanation
Fig. 1 is the structural representation that car cold-storage of the present invention shifts to an earlier date refrigeration air-conditioner.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, a kind of car cold-storage shifts to an earlier date refrigeration air-conditioner, specifically comprises, supply module, control unit, compressor 1, condenser 2, expansion valve 3, water pump 4, frozen water coil pipe 5, frozen water coil pipe fin 6, cold-storage groove 7, first and second three-way diverter valve 8,12, radiator fan 9, the second evaporator 10 and the first evaporator 11.Wherein have more water pump 4 compared with former automotive air-conditioning system, frozen water coil pipe 5, frozen water coil pipe fin 6, cold-storage groove 7, first and second three-way diverter valve 8,12, second evaporator 10, the system had more forms new regenerative cooling system.Water pump 4 is fixed on the bottom of cold-storage groove 7, is closely connected with the second evaporator 10, in the second evaporator 10, the circulation of saline fluid provides power.Frozen water coil pipe 5 and frozen water coil pipe fin 6 closely form one, are fixed on cold-storage groove 7.Fill the salt solution of a constant volume in cold-storage groove 7, use for solidifying ice conserve cold.Solidifying ice amount can control automatically, when solidifying ice amount reaches maximum, also has enough salt solution to circulate for the first evaporator in cold-storage groove 7.When summer, automobile normal running needed refrigeration, compressor 1 is opened, and first and second three-way diverter valve 8,12 is opened, and makes flow of refrigerant through the first evaporator 10, reduces the temperature of air.Night or without car in, can by system modulation cold-storage pattern, now first, two three-way diverter valves 8, 12 open, make flow of refrigerant through frozen water coil pipe 5, salt solution is made to start cold-storage, second day when car is exposed to the sun under the sun, vehicle interior temperature is very high, people cannot enter at once, need to open air-conditioning in advance, under the control of the control unit, water pump 4 is powered, the salt solution in cold-storage groove 7 is driven to start circulation, circulating brine flows through the second evaporator 10, second evaporator 10 is provided with radiator fan 9 above, forced convection blowing cold air under the effect of radiator fan 9, make cooling in car, salt ice in cold-storage groove starts to melt, release latent heat, realize freezing in advance.
Water pump and radiator fan are connected with the power supply storage battery of automobile current generator respectively.Control unit is used for the switching controls that car cold-storage shifts to an earlier date cold-storage and refrigeration in refrigeration air-conditioner.Control unit comprises timing unit, temperature conditioning unit, and timing unit is used for time opening or closes car cold-storage in good time shifting to an earlier date refrigeration air-conditioner; Temperature conditioning unit is used for automatic sensing vehicle interior temperature, and when vehicle interior temperature is higher or lower than design temperature, unlatching or closedown car cold-storage shift to an earlier date refrigeration air-conditioner automatically.Control unit is connected with the power supply storage battery of water pump 4, for the power supply voltage that controls water pump 4 to regulate water velocity in frozen water coil pipe 5 and the refrigerating capacity of unit time.The part that cold-storage groove and frozen water coil pipe contact with air is provided with thermal-insulating sealing layer, for realizing definitely being separated of cold-storage groove and frozen water coil pipe and extraneous air.
This air-conditioning is controlled by control unit.There is timing unit, timing can be carried out as required and make it automatically open in advance; There is temperature conditioning unit, automatic sensing temperature, when summer, when vehicle interior temperature is higher than design temperature, can automatically open; During lower than design temperature, automatically close.The function that the present invention can realize has: normally freeze, and freezes in advance.Detailed below above-mentioned two kinds of patterns to be introduced.
(1) normally freeze
When summer, automobile in the process of moving, need to open air conditioner refrigerating, now open air-conditioning, flow of refrigerant is through three-way diverter valve 8----first evaporator 11----three-way diverter valve 12----compressor 1, blow a cold wind at the first evaporator 11 place and lower the temperature, when temperature reaches the comfort temperature of oneself setting, a/c system is closed automatically.When vehicle interior temperature is opened automatically higher than a/c system during the comfort temperature set.
(2) freeze in advance
When summer, when without car time, air-conditioning can be adjusted to cold-storage pattern, now flow of refrigerant is through the first three-way diverter valve 8----frozen water coil pipe 5----second three-way diverter valve 12----compressor 1, cold reaches the salt solution in cold-storage groove 7 by frozen water coil pipe 5, and salt solution is able to cold-storage.Car stops in the sun, and vehicle interior temperature is very high, and people can not into the car, now need to open air-conditioning in advance.Now have control unit control supply module feed pump 4 and radiator fan 9 to power, ice-cold salt solution, under the effect of water pump 4, flows through the second evaporator 10, circulates, blowing cold air under the effect of radiator fan 9, reduces the temperature in car in advance.When temperature reaches required comfort temperature, under the effect of control unit, system is closed automatically; When temperature is higher than required comfort temperature, refrigeration system is opened automatically in advance, realizes Automatic-cooling in advance.
Car cold-storage of the present invention shifts to an earlier date refrigeration air-conditioner realizing to carry out cold-storage in advance when freezing in advance, when without normal refrigerating mode, can be adjusted to cold-storage pattern and first carry out cold-storage.Controlled by control unit when will freeze in advance, open the second evaporator and carry out refrigeration cool-down.
Car cold-storage of the present invention shifts to an earlier date refrigeration air-conditioner changes refrigerant path by three-way diverter valve, thus realizes the switching between normal refrigeration and cold-storage.
It is have automotive engine to provide power with the same with former air conditioning for automobiles during cold-storage that car cold-storage of the present invention shifts to an earlier date refrigeration air-conditioner at normal refrigerating mode, and the power that when realizing refrigeration in advance, water pump and radiator fan need is provided by vehicle electric motor storage battery.
Car cold-storage of the present invention shifts to an earlier date refrigeration air-conditioner and possesses the function of opening in advance and closing in good time, possesses very large power savings advantages, can be the temperature that in car, creation one is suitable in advance.By refrigerating capacity can be regulated easily to the adjustment of water pump power supply voltage.
