The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of phase-change heat-storage reclaiming system for condensation heat, this reclaiming system for condensation heat is made up of water tank 5, water pump 4, air-cooled unit 7, compressor, air-cooled condenser 6 and several valves, this reclaiming system for condensation heat also comprises phase change heat accumulator 3 and electrical auxiliary heater 2, and phase change heat accumulator 3 is serially connected between compressor and the air-cooled condenser 6; Electrical auxiliary heater 2 one ends connect outlet conduit, and end links to each other with phase change heat accumulator 3 in addition; Water tank 5 is connected with phase change heat accumulator 3 pipelines by water pump 4; Air-cooled unit 7 one end pipelines connect phase change heat accumulator 3, and other holds pipeline to connect compressor outlet 1; Valve k4, k5, k2, k1 are separately positioned between water tank 5 and water pump 4, phase change heat accumulator 3 and air-cooled unit 7, compressor and air-cooled unit 7 and compressor and the phase change heat accumulator 3, are connected with valve k3 between phase change heat accumulator 3 and air-cooled unit 7 and compressor and air-cooled unit 7 interconnective pipelines.
Refrigerant line in the phase change heat accumulator 3 and water lines adopt reverse-flow coil pipe cross arrangement, and phase change heat accumulator 3 inner fillings have phase-change material 104, and phase change heat accumulator 3 inwalls are provided with corrugated plating 103 devices and phase-change material advances to add mouth 108 and outlet 109.Phase change heat accumulator 3 outer walls 102 are provided with the heat-insulation and heat-preservation material.Horizontal refrigerant line adopts the I.S.S copper pipe, and vertical refrigerant line adopts the plough groove type copper pipe.
When air-conditioning system has the demand of recuperation of heat, valve-off k2, open valve k1, after the high temperature refrigerant fluid is discharged from the compressor outlet 1 of air-conditioning system, the phase change heat accumulator 3 of flowing through, phase-change material 104 heat exchange in high temperature refrigerant and the phase change heat accumulator 3, cold-producing medium is equivalent to carry out preliminary cooling, and phase change heat accumulator 3 then utilizes phase transition process that heat is stored.
When the user has the hot water demand, valve k4 opens, and the water in the water tank is through the effect of pump 4 phase change heat accumulator 3 of flowing through, heat exchange in the phase-change material 104 in water and the phase change heat accumulator 3, water is heated, and phase change heat accumulator 3 utilizes the temperature-fall period of phase-change material 104 and phase transition process that heat is discharged.
When air-conditioning system did not have the recuperation of heat demand, valve-off k1 opened valve k2, and the high temperature refrigerant fluid directly enters air-cooled condenser 6 after discharging from the compressor outlet 1 of air-conditioning system.
Below in conjunction with Fig. 2 and Fig. 3 the operation principle of phase change heat accumulator in the utility model is done detailed explanation:
The adverse current phase change heat accumulator 3 of this coiled, it comprises refrigerant inlet 101, is surrounded by the outer wall 102 of heat-insulation and heat-preservation material, corrugated plating 103, phase-change material 104, water inlet 105, water out 106, refrigerant outlet 107, phase-change material adds mouth 108, phase-change material outlet 109.
Phase-change material 104 has the ability that changes its physical state in certain temperature range.With the solid-liquid phase change is example, when being heated to fusion temperature, just produces the phase transformation from solid-state to liquid state, and in the process of fusing, phase-change material 104 absorptions also store a large amount of latent heat; When phase-change material 104 coolings, the heat of storage will be dispersed in the environment in certain temperature range and go, and carries out from liquid state to solid-state reverse transformation.In these two kinds of phase transition process, energy stored or that discharge is called latent heat of phase change.When physical state changed, the temperature of material self almost remained unchanged before phase transformation is finished, and formed a wide temperature platform, though temperature-resistant, the latent heat that absorbs or discharge is quite big.When high temperature refrigerant enters phase change heat accumulator 3 by refrigerant inlet 101, phase transformation material 104 heating temperatures raise gradually, begin when reaching melting point to melt until liquefy, and flow out from refrigerant outlet 107 cold-producing medium cooling back.Water at low temperature enters from refrigerant inlet 105, and high-temp liquid phase-change material 104 release heat also begin to solidify, and water temperature raises, and flows out from refrigerant outlet 106.When air-conditioning system user in service has the hot water demand.When high temperature refrigerant entered phase change heat accumulator 3 by refrigerant inlet 101, water at low temperature entered from refrigerant inlet 105, and cold-producing medium and water directly pass through the coil pipe heat exchange with the form of adverse current, and unnecessary heat then is stored in the phase-change material 104.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
