Abstract

The invention provides an ice storage air-conditioning system using different phase-change materials and relates to the low-temperature thermal energy storing technology. Electric power consumption and electric charge can be minimized. In a cold accumulation groove, a low-temperature latent-heat P.C.M (Phase Change Material) whose phase change temperature is -10 DEG C conducts heat exchange with low-temperature heat energy on the periphery of a coolant circulation heat exchanging Coil where a refrigerating machine is used as an evaporator so as to store low-temperature heat energy via phase change, i.e., changing liquid into solid. Water whose phase change temperature is 0 DEG C conducts heat exchange with low-temperature heat energy by naturally discharging cold on the periphery of a first cold storing groove for storing the low-temperature latent-heat P.C.M (Phase Change Material) so as to store the low-temperature heat energy via phase change, i.e., changing liquid into solid. Via the heat conduction fluid circulation in a heat conduction fluid circulation Coil installed in a second cold storing groove for storing water (H2O), it is achieved that cooled heat conduction fluid is supplied for an air-conditioning indoor unit which is in charge of cooling a building. In this way, the ice storage air-conditioning system is formed.

Description

Use the ice-chilling air conditioning system of different phase-change material

[technical field]

The present invention is a kind of by using different phase-change materials, to improve the ice-chilling air conditioning system of heat exchanger effectiveness.

[background technology]

Generally, cool storage air conditioning technology is that the time drives refrigerator at dead of night, make the undergoing phase transition of water inside cold-storage groove and store low temperature heat energy, the low temperature heat energy stored and heat-transfer fluid carry out heat exchange, through the process of indoor apparatus of air conditioner inner air, to be circulated by comb and the mode cooling indoor temperature is freezed.Utilize water solid to change into ice, the cool storage air conditioning technology absorbing heat energy when melting has widely used decades, is very ripe commercial technology.However, this Cool Storage Technology is because only use water (H 2o) as latent heat materials, by heat-transfer fluid, the air in low temperature heat energy indoor apparatus of air conditioner is circulated at comb, again by carrying out heat exchange with room air, during indoor temperature cooling, the ice of heat-transfer fluid circulation comb outside easily can undergoing phase transition (solid becomes liquid) temperature rise thereupon, the temperature of the low temperature heat energy passed on by comb during the inner air process of heat-transfer fluid indoor set is also risen thereupon, therefore time again with room air heat exchange, room air cooling effectiveness can reduce, so this Cool Storage Technology is still the heat change method being difficult to effectively store low temperature heat energy.

Ice-storage system cold-storage ice-making process style is static mode and dynamical fashion.Static ice making refers to the outer ice making type (ice-on-coil) of the pipe frozen at heat-exchanger surface or internal tank, the mode ice makings such as capsule-type (encapsulated ice), dynamic ice-making refers to that thin ice or ice pellets continue ice making and ice slurry, they are stored in the ice storage ice slurry type (ice slurry) in ice conserve cold groove, the mode ice makings such as ice collection type (ice-harvesting).

Usually general ice-chilling air conditioning system is the ice conserve cold combination of air-conditioning system, and if Fig. 1 is by reezer system, ice conserve cold store groove, heat exchanger, pump, idle call air assembly is formed.Ice conserve cold technique drives refrigerator in the late into the night that electric load is lower, make the comb circulation of ethylene glycol (Glycol) solution of low temperature in ice conserve cold store groove inside, the heat energy of store groove internal water is removed and congeals into ice at the inner comb outer surface of ice conserve cold store groove.In cooling procedure, refrigeration system is static, and the water of ethylene glycol in comb inner loop or ice conserve cold store groove passes through at comb peripheral circulation, and extracts energy from ice.The ethylene glycol of such cooling or frozen water are by while heat exchanger 1 time, and the cooling of building cooling water is recycled to heat exchanger latter 2 times, and the air aircondition being responsible for cooling building is given in supply.

So far, most ice storage technology uses latent heat materials water (H 2o), generate ice below 0 DEG C after, ice stores low temperature heat energy while aqueous phase change, is used in the sensible heat ice conserve cold cooling procedure of foregoing description according to temperature difference.

[problem-solving approach]

The low temperature latent heat P.C.M (Phase Change Material) of-10 DEG C of phase change (liquid becomes solid) in order to achieve the above object, is stored in the 1st cold-storage groove by the present invention;

The refrigerant circulation heat exchange tube bank (Coil) of the low temperature latent heat P.C.M (Phase Change Material) stored in the 1st cold-storage groove and the effect of performance evaporimeter carries out heat exchange; Refrigerant circulation heat exchange tube bank (Coil) and by compressor, condenser, the refrigerator unit (Unit) that expansion valve is formed connects, and the 1st cold-storage groove inside is included in the 2nd cold-storage groove; That store in the 2nd cold-storage groove is water (H 2o); Water (H 2o) phase transformation turns to solidified ice and heat-transfer fluid generation heat exchange, and heat-transfer fluid is cooled, and its structural feature is that the heat-transfer fluid of described cooling is supplied to the inside of indoor apparatus of air conditioner by heat-transfer fluid comb (Coil) circulation.

[effect]

As mentioned above, the present invention is the air-conditioning system using different phase-change material, is to use phase change (liquid becomes solid) temperature to be the P.C.M (PhaseChange Material) made in eutectic salts (Eutectic Salf) mode of-10 DEG C and use phase change temperature to be the water (H of 0 DEG C 2o), the system of refrigerator is driven at the late night hours of low electric load, the cheap electricity charge, the phase change temperature of the 1st cold-storage groove internal reservoir is that the eutectic salts (Eutectic Salf) of-10 DEG C stores low temperature heat energy by phase change (liquid becomes solid), makes the phase change temperature of the 2nd cold-storage groove internal reservoir be the water (H of 0 DEG C with the low temperature heat energy of cooling naturally in the 1st cold-storage groove simultaneously 2o) low temperature heat energy is stored by phase change (liquid becomes solid).Herein, the copper (Cu) that available pyroconductivity is high or aluminium (Al) material make the 1st cold-storage groove and improve heat conducting efficiency.

The low temperature heat energy using different phase-transition material to store by day is to cool interior of building, by carrying out the heat-transfer fluid of heat exchange with the air of interior of building, carry out heat exchange to cool again with the ice of the storage low temperature heat energy in the 2nd cold-storage groove inside, now, along with the change of time, by carrying out heat exchange with heat-transfer fluid, temperature rises and makes the ice phase transformation of solid state turn to the water (H of liquid condition 2o), supply is uprised to the temperature of the heat-transfer fluid of the indoor apparatus of air conditioner of interior of building, shortcoming is that the air conditioner refrigeration effect of interior of building reduces, the low temperature heat energy of the storage low temperature latent heat P.C.M (Phase ChangeMaterial) of-10 DEG C of the 1st cold-storage groove inside, can make the water (H of cooling naturally below 0 DEG C 2o) solid (ice) state maintains for a long time, the supply continued after the ice of heat-transfer fluid and 0 DEG C carries out heat exchange is to the indoor apparatus of air conditioner of the interior of building of low temperature heat energy less than+10 DEG C, compared with traditional mode, be make the improved very useful invention greatly of the cooling effectiveness of interior of building air-conditioning.
