Technical field
The utility model relates to refrigerating circulatory device, relates in particular to the refrigerating circulatory device that is provided with cold-storage phase transformation facility.
Background technology
Raising along with people's living standard, domestic air conditioning has entered common people house, domestic air conditioning also increases sharply with electric energy consumption proportion in the urban distribution network power consumption simultaneously, form can't bear the heavy load of power system in summer, not only consume a large amount of non-renewable resources, cause skyrocketing of energy prices, sulfide and nitride that mineral matter burning simultaneously produces have also caused environmental pollution.
Summary of the invention
The utility model provides a kind of refrigerating circulatory device with cold-storage phase transformation facility, overcoming the prior art defective, and improves the operational efficiency of air-conditioner, reduces the compressor power consumption.
The utility model purpose is to realize like this, the refrigerating circulatory device of this band cold-storage phase transformation facility, it comprises compressor, at the condenser that carries out heat exchange between refrigeration working medium and outdoor air, be used for carrying out between refrigeration working medium and room air the evaporimeter of heat exchange, it is characterized in that between the fin of evaporator coil, being provided with cold-storage phase transformation facility.
Described cold-storage phase transformation facility is a latticed chamber frid structure, is filled with cold storage body in the groove of chamber at interval.
Described cold storage body adopts organic admixture or eutectic salts.
The technological progress that the utility model is obtained: because cold-storage phase transformation facility is set between the fin of evaporator coil, and in being provided with, this fills at interval the cold storage body of organic admixture or eutectic salt cold-storage phase-change material, adopt the supply and demand of this energy accumulating technique adjustable energy saving, can realize the peak load shifting of power load to electrical network, can improve power equipment utilization rate, equilibrium energy system, cut down the consumption of energy, save operating cost and can realize the efficient and rational utilization of energy.
The utility model selects the organic compound of suitable phase transition temperature or the cold storage body of eutectic salts to be filled at interval in the groove of latticed chamber, this cold-storage phase-change material has higher latent heat of phase change, suitable phase transition temperature, no surfusion and heat endurance preferably, can be applicable in the chilling air conditioning system, can improve the cold inertia of system, strengthened the heat transfer of evaporimeter, and can improve the evaporating temperature of system, increase the efficient of system.Both can guarantee the requirement of indoor temperature and humidity, improve the operational efficiency of air-conditioner again, reduce the running time of compressor, reach energy-saving effect preferably, save the power consumption of compressor of air conditioner, reduce the operating cost of device.The cold-storage phase transformation facility of having filled this cold-storage phase-change material is used for kind of refrigeration cycle, with air-conditioning system when not having cold and hot amount demand, convenient and cold and hot amount that cheaply obtain temporarily stores and can use at any time, erected and produced cold and hot amount and use cold and hot amount asynchronous " bridge ", make air-conditioning system can utilize the scope of energy storage to be expanded, large-scale popularization is used this novel energy-storing device in air-conditioning system, not only the energy conservation of air-conditioning system can be promoted effectively, and considerable economic and environmental benefit can be brought.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is a cold-storage phase transformation facility assembly structure schematic diagram.
Fig. 3 is a cold-storage phase transformation facility structure schematic diagram.
The specific embodiment
As shown in Figure 1, the refrigerating circulatory device of this band cold-storage phase transformation facility comprises and is used to suck and the compressor 1 of compressed gaseous refrigeration working medium, between refrigeration working medium and outdoor air, carry out the condenser 2 of heat exchange, be used for carrying out between refrigeration working medium and room air the evaporimeter 4 of heat exchange, throttle expansion valve 3 in 4 in condenser 2 and evaporimeter, 6 of fins at evaporimeter 4 coil pipes are provided with cold-storage phase transformation facility 5 (as shown in Figure 2), this cold-storage phase transformation facility 5 is a latticed chamber frid structure (as shown in Figure 3), it adopts stainless steel material to make, fill cold storage body 7 backs in the groove of chamber at interval and form separately independently enclosure space, cold storage body 7 adopts organic admixture or eutectic salt cold-storage phase-change material.Wherein organic admixture can adopt the eutectic mixture that is made of by a certain percentage sad and aliphatic acid; The mixture that eutectic salts can adopt five aqueous sodium persulfate compounds, water and additive allotment to form.The phase transition temperature of cold-storage phase-change material can change between 10～5 ℃; latticed chamber frid is placed on the surfaces externally and internally of evaporimeter 4; portion of energy in the evaporimeter 4 is absorbed by the cold-storage phase-change material; the cold-storage phase-change material has been become solid-state by liquid state; cold is stored in the cold-storage phase-change material; after compressor 1 is shut down; the cold-storage phase-change material is by solid-state liquefy; the while released cold quantity; utilize air-flow and cold storage body forced convection again, cold is sent in circulation, discharges the cold of storage; the supply surrounding environment is used, can keep system to move several hrs continuously under the situation that does not have energy input.
The utility model is the refrigeration working medium motive force with the compressor of traditional aircondition, is heat absorption, heat release parts with evaporimeter and condenser, is the phase-change heat transfer medium with the refrigeration working medium, forms kind of refrigeration cycle, to reach the purpose of taking away indoor heat.When the compressor unlatching, when evaporating temperature can satisfy the refrigeration requirement and be lower than the phase transition temperature of the cold-storage phase-change material in the cold-storage phase transformation facility 5, compressor will reach whole cold-storage phase-change materials always and all melt.At this moment, evaporating temperature is lower than temperature in the room, and indoor temperature reaches design temperature, and compressor cuts out.When compressor cuts out, there is refrigeration demand in the middle of energy storage phase change material, to be met, be accompanied by the whole melting process of energy storage phase change material, until whole energy storage phase change materials all solidifies, compressor just can be opened again.
