Description
Technical field
The utility model relates to a kind of refrigeration plant with refrigeration and cool storage function, belongs to art of refrigeration units.
Background technology
Refrigeration plant, such as the refrigerating automobile that in the cold chain transportation industry, occupies critical role and convenient and practical Mobile refrigerator etc., all need to be in special time continual and steady cooling, even comprise it being not have also will to continue cooling in the situation of power supply.Example refrigerating automobile described above carries out refrigerating when transportation or Mobile refrigerator when moving, 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 the particular space is realized refrigeration.(civil power is fixed power source, and it is static mobile refrigeration compressor power supply that fixed power source is applicable to 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 mobile refrigeration compressor power supply such as refrigerating automobile or Mobile refrigerator) etc., in case and power supply can't be powered (for example without commercial power supply, or generator does not turn round and can't power, or accumulator electric-quantity is used up) time, refrigeration compressor just can't be worked, and evaporimeter also just can't outwards be released cold.Obviously, the refrigeration of this mode is affected by power supply, and unreliable.
Summary of the invention
The utility model purpose provides a kind of refrigeration plant with refrigeration and cool storage function, can reliably freeze.
For achieving the above object, the technical solution adopted in the utility model 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, the first magnetic valve, the first expansion valve, evaporimeter and the gas-liquid separator that connects and composes successively the loop; Described cold accumulation system comprises refrigeration compressor, condenser, reservoir, device for drying and filtering, the second magnetic valve, the second expansion valve, cold-storage device and the gas-liquid separator that connects and composes successively the loop.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described condenser is 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, described refrigeration compressor is totally-enclosed brush DC Refrigerating Compressor with Inverter, more energy-conserving and environment-protective.
3, in the such scheme, described expansion valve is the reducing pressure by regulating flow device, effect be from after the moist steam that becomes low-temp low-pressure after the high temperature of condenser, high pressure liquid refrigerant cooling, the step-down in evaporimeter absorbing heat reach refrigeration.Expansion valve is that the degree of superheat by the evaporimeter end changes and comes autocontrol valve to open and flow.
4, in the such scheme, described 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, prefill valve is communicated with the sealed hollow chamber, the cold-producing medium of refrigeration compressor is delivered in the evaporation pipeline by 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, the first magnetic valve of described refrigeration system and the second magnetic valve of cold accumulation system are not opened simultaneously, generally also do not need in actual use to open simultaneously, and namely 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 the first magnetic valve and the second magnetic valve are not opened simultaneously, if both open simultaneously, and the also ratio of wayward compressor institute conveying capacity.
The utility model operation principle 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 the first magnetic valve and the second magnetic valve of control refrigeration compressor.For example civil power (municipal electric network source) is being arranged, when the power supply such as generator or battery is powered, 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 startup refrigeration compressor, open again the second magnetic valve of cold accumulation system, close the first magnetic valve of refrigeration system, control makes cold accumulation system work, refrigeration compressor with cold-producing medium along condenser, reservoir, device for drying and filtering, the second magnetic valve, the second expansion valve, cold-storage device and gas-liquid separator are carried, cool storage medium in the cold-storage device solidifies, and has saved cold.
When refrigeration plant need to 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 the first magnetic valve and the second magnetic valve, is let cool 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), having in the Power supply situation, start refrigeration compressor, and open the first magnetic valve of refrigeration system, close the second magnetic valve of cold accumulation system, control makes refrigeration system work, refrigeration compressor is carried cold-producing medium along condenser, reservoir, device for drying and filtering, the first magnetic valve, the first expansion valve, evaporimeter and gas-liquid separator, evaporimeter is kept low temperature to the particular space released cold quantity.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
1, the utility model is simple in structure, and cost is low.
2, the utility model 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 utility model 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.
