Description
Technical field
The utility model relates to a kind of air conditioner condensation heat reclamation device, particularly a kind of air-cooled heat pump unit heat reclamation device.
Background technology
The air-cooled heat pump unit condenser heat that refrigerating operaton is produced summer is very huge, is generally about 1.25 times of refrigeration duty.Condensation heat directly enters atmosphere, not only causes great energy waste, and environment temperature is raise, and produces serious thermal pollution.In fact, though summer a lot of buildings domestic hot-water's demand is also all arranged, this part domestic hot-water obtains by coal-fired, fuel oil or gas fired-boiler, energy utilization rate is very low, has also aggravated energy scarcity and problem of environmental pollution simultaneously.Therefore, consider all or part of recovery of condensation heat is used to heat the domestic hot-water, can reach energy savings, satisfy the purpose that domestic hot-water's demand is killed two birds with one stone.In addition, air-cooled heat pump unit then can utilize in the heat pump part of compressor air-discharging to cross heat content heating domestic hot-water in winter.
At present, above-mentioned recuperation of heat mode mainly contains two kinds of water accumulation of heat and phase-transition heat-storages.Because stage and discontinuity that the domestic hot-water uses, the mode that directly adds hot tap-water can't solve the asynchronous problem that operation of air conditioner and hot water produces and the imbalance problem of hot water amount and condenser heat.The water thermal storage equipment is simple, has good heat conductivity, cold-producing medium and the high advantage of water sensible heat transfer efficient, but the heat storage capacity of water is less, certainly will cause the shortcoming that increases retaining casing volume.The latent heat of phase change of phase change heat storage material is big, generally only cold, do not fold, stable performance, its shortcoming is that thermal conductivity and density are less, and owing to will pass through twice heat transfer process of cold-producing medium---heat-storing material---between the water in the phase change heat accumulator, heat exchange efficiency is greatly diminished.
Summary of the invention
The purpose of this utility model is to provide a kind of air-cooled heat pump unit heat reclamation device, by selecting suitable phase-change material, with valve and pipeline control device, phase-transition heat-storage and water accumulation of heat dual mode are combined, not only can solve asynchronous that operation of air conditioner and hot water produces, the imbalance problem of hot water amount and condenser heat, but and the advantage of two kinds of heat storage types of focus utilization, improve heat recovery system, improve heat recovery efficiency.
For achieving the above object, the utility model adopts a phase change heat accumulator of series connection and a water storage heater before Air-Cooled Heat Pump Unit, the high temperature refrigerant of compressor outlet is introduced storage heater, carry out the sensible heat of heat pump, the recuperation of heat of latent heat, dispose auxiliary heater simultaneously, realization system winter heating, produce domestic hot-water when freezing summer.
Description of drawings
Fig. 1 is the utility model air-cooled heat pump unit heat reclamation device structural representation;
Below in conjunction with accompanying drawing the utility model is described in further detail.
The specific embodiment
Referring to Fig. 1,1 is compressor, and 4 is phase change heat accumulator, and 5 is the water storage heater, and 6 is elevated tank, and 7 is water pump, and 12 is Air-Cooled Heat Pump Unit, and 8 is the air cooling heat exchanger fan of Air-Cooled Heat Pump Unit 12.When Air-Cooled Heat Pump Unit at refrigerating operaton and when producing the domestic hot-water in summer, valve K2 closes, valve K1, K3, K6, K7 opens, the high temperature refrigerant steam of being discharged by compressor 1 outlet is through valve K1, K3 and pipeline thereof feed phase change heat accumulator 4, so the phase-change working substance of phase-transition heat-storage 4 absorbs the heat from high temperature refrigerant steam, make high temperature refrigerant steam be cooled to superheated steam gradually, saturated vapor and liquid or subcooled liquid, flow out phase change heat accumulator 4, flow into water storage heater 5 through pipeline again, carry out heat exchange with the water in the water storage heater 5, the unnecessary heat of refrigerant vapour or liquid is stored by the water absorption, refrigerant vapour or the liquid that flows out from water storage heater 5 at last, enter Air-Cooled Heat Pump Unit 12 through valve K7 and pipeline thereof, carry out the refrigerating operaton of air-cooled heat pump unit.The domestic hot-water who carries out simultaneously with above-mentioned operation produces, be that cold water by elevated tank 6 flows into water storage heater 5 through pump 7, valve K6 and pipeline, and carry out heat exchange with water in the water storage heater 5, then, what flow out water storage heater 5 tentatively adds hot water, flow into phase change heat accumulator 4 through pipeline again, the latent heat that absorbs phase-change working substance in phase change heat accumulator 4 further heats, do not reach the temperature that instructions for use is set if flow out the domestic hot-water of phase change heat accumulator 4, then continue to be heated to temperature required again by the electrical auxiliary heater 3 of flowing through, send into user side.K4 is the automatically controlled valve that is communicated with between exit and the refrigerant vapour that enters Air-Cooled Heat Pump Unit 12 or the liquid-inlet place of the refrigerant vapour of phase change heat accumulator 4 or liquid, be communicated with the refrigerant temperature sensors control of the switching of valve K4 by phase change heat accumulator 4 exits, temperature is lower than setting value, then valve 4 is opened, refrigerant vapour or liquid, directly enter Air-Cooled Heat Pump Unit 12, otherwise refrigerant vapour or liquid flow into water storage heater 5 through pipeline, and unnecessary heat is absorbed by the water in the water storage heater 5.Refrigerant vapour or liquid outlet at water storage heater 5 are provided with temperature sensor, and when being higher than set temperature value, the air cooling heat exchanger fan 8 of control Air-Cooled Heat Pump Unit 12 starts, and further discharges the condensation heat of cold-producing medium.When Air-Cooled Heat Pump Unit heating operation and when producing the domestic hot-water in the winter time, because utilizing compressor 1 exhaust outlet to cross heat content heats, so only taking a part of heat content of crossing heats, control is communicated with valve K4 and closes, valve K1, K3, K6, K7 open, and the aperture of appropriate by-pass valve control K2, entering the high temperature refrigerant flow of phase change heat accumulator 4 and water storage heater 5 with adjusting, the process of its heating cold water is identical during refrigerating operaton with above-mentioned summer.If the domestic hot-water who produces does not reach the temperature that instructions for use is set,, continue to be heated to the temperature required user side of sending into then again by flow path auxiliary heater 3.
Beneficial effect
The utility model heat recovery utilizes phase-transition heat-storage and two kinds of accumulation of heat sides of water accumulation of heat Formula, it is big to have a phase change heat storage material latent heat of phase change, the heat exchange efficiency height, volume is little, and system architecture is simply special Point can effectively improve heat recovery system, improves heat recovery efficiency, recycles condensation heat summer, winter profit Part with compressor air-discharging is crossed heat content, realizes freezing, heating, produce triple functions of domestic hot-water.
