Description
Technical field
The present invention relates to a kind of refrigeration plant, belong to art of refrigeration units with refrigeration and cool storage function.
Background technology
Refrigeration plant for example occupies the refrigerating automobile of critical role and convenient and practical mobile refrigerator etc. in the cold chain carrier, all need be in special time continual and steady cooling, even comprise it being not have also will to continue cooling under the situation of power supply.When perhaps mobile refrigerator moved when for example above-mentioned refrigerating automobile carried out the refrigerating transportation; Even there is not power supply (fixed power source or portable power source) power supply this moment, still require refrigerating automobile or mobile refrigerator to continue cooling to food or the medicine that stores.
The common refrigeration modes of refrigeration plant is to adopt refrigeration compressor and evaporimeter to connect and compose refrigeration system at present; Refrigeration compressor work when obtaining power supply (fixed power source or portable power source) power supply; Cold-producing medium is delivered to evaporimeter; And evaporimeter released cold quantity in particular space is realized refrigeration.(civil power is a fixed power source, and fixed power source is applicable to be static refrigeration compressor power supply of not moving for the power supply of refrigeration compressor power supply can be civil power, generator or battery; Generator and battery are portable power source; Portable power source can be the refrigeration compressor power supply that refrigerating automobile or mobile refrigerator etc. move) etc.; And in case power supply can't be supplied power when (for example do not have commercial power supply, or generator do not turn round and can't supply power, or accumulator electric-quantity being used up); Refrigeration compressor just can't be worked, and evaporimeter also just can't outwards be released cold.Obviously, the refrigeration of this mode is influenced by power supply, and unreliable.
Summary of the invention
The object of the invention provides a kind of refrigeration plant with refrigeration and cool storage function, can reliably freeze.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of refrigeration plant with refrigeration and cool storage function; Comprise refrigeration system and cold accumulation system, wherein refrigeration system comprises refrigeration compressor, condenser, reservoir, device for drying and filtering, first magnetic valve, first expansion valve, evaporimeter and the gas-liquid separator that connects and composes the loop successively; Said cold accumulation system comprises refrigeration compressor, condenser, reservoir, device for drying and filtering, second magnetic valve, second expansion valve, cold-storage device and the gas-liquid separator that connects and composes the loop successively.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said condenser is a heat-exchange apparatus, and its effect is the high temperature refrigerant superheated vapor cooling of refrigeration compressor discharge and is condensed into highly pressurised liquid that cold-producing medium liberated heat in condenser is taken away by cooling medium.
2, in the such scheme, said refrigeration compressor is totally-enclosed brush DC frequency conversion refrigeration compressor, more energy-conserving and environment-protective.
3, in the such scheme, said expansion valve is the throttling decompression device, and effect is reaching refrigeration from evaporimeter, absorbing heat after the moist steam that becomes low-temp low-pressure after the high temperature of condenser, high pressure liquid refrigerant cooling, the step-down.Expansion valve is to change through the terminal degree of superheat of evaporimeter to come autocontrol valve unlatching and flow.
4, in the such scheme; Said cold-storage device comprises housing, evaporation pipeline and prefill valve; Its middle shell has a sealed hollow chamber, filling cool storage medium in the sealed hollow chamber, and prefill valve is communicated with the sealed hollow chamber; The cold-producing medium of refrigeration compressor is delivered in the evaporation pipeline through the mouth of pipe of evaporation pipeline, and the pipeline section of evaporation pipeline is dipped in the cool storage medium in the sealed hollow chamber.
5, in the such scheme, first magnetic valve of said refrigeration system and second magnetic valve of cold accumulation system are not opened simultaneously, generally also do not need in actual use to open simultaneously, and promptly cold accumulation system and refrigeration system are selected one and carried out work; In addition, it also is because the energy of evaporimeter and the required refrigeration compressor of cold-storage device does not wait that first magnetic valve and second magnetic valve are not opened simultaneously, opens simultaneously as if both, the ratio of also wayward compressor institute conveying capacity.
Operation principle of the present invention is: temperature controller is set, and temperature controller can be according to detecting the contrast of air themperature and preset temperature, with start and stop, the clutch of generator and the switching of first magnetic valve and second magnetic valve of control refrigeration compressor.When having that for example power supplys such as civil power (municipal electric network source), generator or battery are supplied power; And when refrigeration plant does not need cooling again simultaneously, temperature controller control adhesive generator (or be communicated with civil power or connect battery), and start refrigeration compressor; Open second magnetic valve of cold accumulation system again; Close first magnetic valve of refrigeration system, control makes cold accumulation system work, and refrigeration compressor is carried cold-producing medium along condenser, reservoir, device for drying and filtering, second magnetic valve, second expansion valve, cold-storage device and gas-liquid separator; Cool storage medium in the cold-storage device solidifies, and has saved cold.
When refrigeration plant need continue cooling, at first use the cold in the cold-storage device, need not to the refrigeration compressor power supply, refrigeration compressor is closed down in temperature controller control, closes first magnetic valve and second magnetic valve, puts cold by the cool storage medium in the cold-storage device.
When the cold of cold-storage device is used up; Temperature controller control adhesive generator (or be communicated with civil power or connect battery) is having under the power supply electric power thus supplied, starts refrigeration compressor; And open first magnetic valve of refrigeration system; Close second magnetic valve of cold accumulation system, control makes refrigeration system work, and refrigeration compressor is carried cold-producing medium along condenser, reservoir, device for drying and filtering, first magnetic valve, first expansion valve, evaporimeter and gas-liquid separator; Evaporimeter is kept low temperature to the particular space released cold quantity.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, the present invention is simple in structure, and cost is low.
2, the present invention adopts cold accumulation system and refrigeration system two cover system work, still can work a period of time under the power supply supply situation not having, so cooling is more reliable.
3, the present invention can use mains supply and be in the cheap paddy electricity time power supply of the electricity charge at civil power when giving the cold-storage device cold-storage, and paddy electricity price lattice are cheap, so escapable cost, and this power supply does not have discharge of poisonous waste, more energy-conserving and environment-protective.
