Description
At present a large amount of family expenses cold-warm electric appliances constantly crowd into hotel, shop, school, hospital, office space and numerous domestic consumers, and also have the constantly gesture of expansion.But because the family expenses cold-warm electric appliance is noted unit function and qualitative raising as commodity and manufacturer in the development more, ignore multiple function unit and compiled pool work when using, make present multiple function unit when same environment uses, just produced conflicting, performance is disturbed, the job family system is overlapping, and energy consumption is big or the like.
For example: refrigerator be consumed the electricity with the transfer of heat in the refrigerator in room air, and air-conditioning again power consumption will shift the heat that comes and indoor original heat and transfer to outdoor air together again and share, clearly be contradiction, interference, the overlapping use of power consumption job family system.
And for example: also people drank, do washing, cooked just, bathing is with the peak of hot water the peak season of operation of air conditioner.Present air conditioner unit with the speed of 1500-4500W/h with the outdoor public hazards that cause of transferring to of indoor heat difficulty, can go heating and meanwhile consume various situations, drink, bathing, cook, hot water such as laundry, the existing heat energy of i.e. waste clearly, easily energy consumption heats again again.
Develop into present stage, usually need the cold-warm electric appliance of various different functions and use simultaneously be set at same environment, so their heat shifts and power consumption heat just can not be again blindness, at random, they need a perfect system, heat transfer and power consumption to them heat the concentrated regulation and control of making overall plans, and science utilize waste heat, minimizing can heat, and improves the Energy Efficiency Ratio of cold-warm electric appliance.
And native system is just in line with above principle, the multiple function of family expenses cold-warm electric appliance is integrated in one, with many of off-premises station tractions, the indoor set of various functions, unit function and quantity can be with user's arbitrary combination, reached advanced, practical, energy-conservation, high-grade, low-cost boundary.

Cycle of higher pressure: thus the time temperature pleasant heat heat of stopping to freeze, cycle of higher pressure is deactivated.
Low pressure recycle: freezing and refrigeration can be shut down, and also can work by cyclic process in summer independent loops.
4. circular chart (ginseng figure two) (table one)
Cycle of higher pressure: 3-4-5-6-7-8-3.Point 3 is the hiigh pressure stage suction condition, and is compressed to point 4 high pressure gas states, through being cooled to a little 5 supercooled states, high undercooling state point 6 before backheat reaches expansion valve again, be depressured to a little 7 evaporations through expansion valve and expand, point 8 is the states of evaporating, and steam is superheated to a little and 3 gets back to the high pressure suction condition.
Low pressure recycle: 1-2-3-4-5-6-9-10-1.Point 1 is the low pressure suction condition, is compressed to a little 2, again through being cooled to high pressure suction condition point 3.Recompression reaches a little 4, is cooled to a little 5 supercooled states, reaches a little 6 cryogenic through backheat again, through expansion valve be depressurized to a little 9 reach after evaporating a little 10 again backheat arrive and put 1 a low pressure suction condition.
High-low pressure circulation meets at superposition synchronous operation behind 3 states a little and is gone by separately expansion throttling state shunting to putting 6 backs, and the cooling of the compression of increase 1-2 and 2-3 meets at a little 3 with cycle of higher pressure once more in the low pressure recycle.
(3) emphasis principle and original paper specification:
1. energy storage central controller principle and energy storage central controller design
Principle: the control of energy storage collection is to carry out one of important measures of multiple function amalgamation operation.It is poor that it has solved the randomness and the refrigerant flow of each unit operation in multiple function or many unit combined runnings, effectively coordinated the various contradictions in the systemic circulation, wherein: (ginseng figure three).
High pressure (the P of pressure pan (1) contain one constant volume
K=1.9423MPa) supercooled liquid (T
K=-25 ℃) and lead to each unit, guarantee that each unit consumes at random by the operating condition of setting separately.When making a jar internal pressure, consumption drops to certain value, then feed back compressor start work, reach the higher limit compressor up to the jar internal pressure and quit work, constantly the energy (refrigeration) replenishes, stable only lower limit fluctuation range has ensured that each function unit normally fully plays in the system.
The middle jar high pressure (P of (2) contain one constant volume that presses
M=0.6213MPa) dry saturated steam is pressed steam during wherein free middle pressure steam of recalling to stream and low-pressure stage compression are cooled.Its jar be the meet (being circular chart mid point 3 states) of high-low pressure circulation just, thus because of having a constant volume to have buffering, it weakens the provisional inharmonious effect that high pressure sucks and low pressure exhaust is produced, and have the vapor-liquid separation effect concurrently.
The low pressure dry flue gas of low pressure jar (3) contain one constant volume is the steam that is refluxed by the low pressure evaporation, the very low (T of temperature
MAbout=-20 ℃) promptly there is certain backheat to be worth, and have the vapor-liquid separation effect concurrently.
On structural design, the energy storage central controller is by high, normal, basic three stage pressure jars, and the outermost layer that wraps attached its formation with the form of three layers of interior China and foreign countries layer by layer is surrounded by heat insulation layer (4).Prevent that a jar self-energy (refrigeration) runs off, in the low pressure jar, establish 6 product heat cal rods (5), bend to the hyperbolic wire, pass intermediate pressure jar and pressure pan (welded seal) and make low-pressure steam from the bottom to top flow circuit and high and medium voltage jar inner refrigerant backheat exchange within it.See that on the whole this designs not only compact conformation, help the backheat exchange, help vapor-liquid separation, and jar internal and external pressure balance negative function, make each layer tank skin only bear inside and outside differential pressure, alleviated the bearing strength of tank skin.
2, dividing potential drop energy-saving principle and dividing potential drop scheme:
The dividing potential drop throttling is to carry out two of the important measures of multiple function amalgamation operation, native system has solved the dividing potential drop evaporation problem that multiple function amalgamation moves circulation time with the capillary-compensated step-down that the expansion valve throttling step-down of having set different evaporating pressures has replaced in the current refrigerator air conditioner unit, and each function unit refrigeration degree of depth that the swollen evaporation of rising obtains separately under the pressure of setting separately according to unit operating condition carrying out at random separately under the situation of using same high pressure supercooled liquid is independent of each other.
The dividing potential drop scheme is controlled high pressure P respectively with two groups of outer balanced type heating power expansion valves of high evaporation pressure and low evaporating pressure
M=0.6213MPa (air-conditioning evaporating pressure) and low pressure P
OThe decompressional expansion vaporization cycle process of=0.2692MPa (freezing and refrigeration evaporating pressure), each unit are then set control according to the difference of function by temperature control temperature-sensitive bag pressure power, and the flow of cold-producing medium and expansion valve are opened the frequency and obtained the required refrigeration degree of depth.
3. two stages of compression principle and two-stage coenosarc compressor design
Two stages of compression be carry out multiple function amalgamation operation important measures three.Conflux and just can finish the overall process of high-low pressure superposition circulation corresponding to just certainly existing a combined pressure in the dividing potential drop throttle system circulation.Native system adopts two stages of compression, promptly sets up low-pressure stage compression and cooling, makes low-pressure steam boost to intermediate pressure (being circular chart point 3) and cycle of higher pressure backflow steam and converges superposition and circulate synchronously.
It is R that its structure of two-stage coenosarc compressor (ginseng figure four) adopts the sealed refrigeration agent
22, same motor coenosarc is adopted in high pressure compressed and low pressure compression.High-pressure pipe (1) communicates with upper chamber (2), and blast pipe (3) directly communicates with high pressure compressor cylinder body (4), and low-pressure inlet pipe (5) directly communicates with low pressure compressor cylinder body (6), and blast pipe (7) communicates with lower chamber (8).Make that going up lower chamber is in intermediate pressure together.In order to avoid bearing (9) sealing place (10) has pressure reduction.Be to reduce resistance, valve is not established in the rotary compressor intake and exhaust, and establish electromagnetism check valve and compressor in the blast pipe appropriate location synchronous or lag behind and moved in 0.1 second.The design parameter high pressure designs P with air conditioning condition
K=2115.7KPaT
K=54.4 ℃.Low pressure is with freezing operating mode parameter designing, P
O=-209.22KPaT
0=-24 ℃.The intermediate pressure parameter is with air-conditioning evaporation return-air parameter designing P
M=621.KPaT
M=7 ℃.Flow and flow proportional calculate according to the unit load condition and get.
4, UTILIZATION OF VESIDUAL HEAT IN principle and segmentation design of condenser.
Principle: the heat extraction of the little split-type air conditioner of 2000W load is exactly 2245kcar/h, and a 200W refrigerator heat extraction load is exactly 245kcar/h, and the total heat duties after system's amalgamation is 2600kcar/h 540kcar/h or more at most at least.If 56% thermic load is recovered utilization, per hour hand over normal-temperature water 35-62L is heated to 75 ℃ of usefulness that satisfy large, medium and small family fully.And that prior principle is the consumption of hot water is big more, not only does not consume energy, and favourable to circulating more, improves refrigeration coefficient ξ, energy-saving and cost-reducing, reduces Tail Pipe Temperature, alleviates compressor load.
Segmentation design of condenser (ginseng figure five) water-cooled section is used for the refrigerant cools more than 50 ℃.Air-cooled section refrigerant cools that is used for below 50 ℃.The water-cooled section is the heat exchange of vertical water hull coil pipe, and in water hull (1) (thermal source of instant heating hydrophone) central authorities, the heat power that is produced by heat exchange picks constantly circulating from bottom to top of moving water to the high-low pressure blast pipe with the vertical parallel discs of outer and inner two dishes.Hot water goes out from water hull (6) suitable for reading, and backwater advances from water hull end opening (7).Recirculated water is heated the back hot water supply device and stores consumption, and cold-producing medium therefrom obtains cooling.Should cut off except that summer and the water heater path, water hull discharges water.During the winter operation of heat pump, be that low-temperature steam after the evaporation heat absorption from bottom to top flows in the high pressure coil pipe (2), and still be the superheated vapor that compressed in the low pressure coil pipe (3), from top to bottom with high-voltage tube in back-steam sufficient heat exchange in water hull, improve the back-steam temperature, in order to avoid drop refluxes.
Air-cooled section is fin (4) serpentine coil structure, the low pressure coil pipe preceding high pressure coil pipe after, the low pressure coil temperature is low first, ought to formerly contact with cold air during condensation.Second high pressure coil pipe heat absorption low pressure coil pipe still dispels the heat during operation of heat pump, low-voltage tube in front can play the defrost effect, and leave waste heat and can be reclaimed by the high pressure coil pipe of back, check valve and expansion valve are installed in high pressure coil pipe bifurcation road above air-cooled section, and operation is used to change according to the season.The thermic load amount that design parameter is air-cooled section should be by more than 85% of system's total heat duties, prevents from that summer fever hydrophone consumption is very few to cause overload.
5, multiple function unit combinatorial principle and assembled scheme.
Principle: for avoiding the overlapping use of job family system, alleviate indoor voice, all low-temperature receivers (being refrigeration system) parts are combined to off-premises station without exception, by the indoor multiple function of more high-power output traction or many units, constant for ensureing indoor unit function performance, its travelling mechanism (not comprising low-temperature receiver) remains unchanged or is constant substantially.Cancelled reduce the shape-designing difficulty behind the cold source system after, should pay much attention to the graceful moulding and the moulding that forms a complete set of.
Assembled scheme one: (Fig. 6-1) is for band kitchen one-storey house and be with kitchen building (being low-grade living conditions) can adopt 2000W air-conditioning 250L combination refrigerator (2) 30L water heater (3) combination.Air-conditioning can adopt and be horizontally-arranged at the refrigerator top, is similar to console formula air-conditioning outward again like high-grade bar cabinet, shows class, saves the space, is easy to installation and maintenance.
Assembled scheme two: (Fig. 6-2)) be that 2000W wall hanging split-type air conditioner (5) 400L refrigerator (6) 100L refrigerator (7) 40L water heater (3) combination can be adopted in one lavatory, one kitchen, one Room, a Room (being middle-grade living conditions), square hall's area is less, can adopt the open refrigerator of 400L with to banishing cold and 100L refrigerator conduction cold scattering is safeguarded that temperature is lower than the outdoor room that is higher than in the Room and played transitional function.
Assembled scheme three: (Fig. 6-3) is that two 2000W wall hanging split-type air conditioners (5) 400L refrigerators (6) 150L refrigerators (7) 80L water heaters (3) combination can be adopted in one lavatories, one kitchen, one Room, two Room (being high-grade living conditions)
Assembled scheme four: it increases with the room basically and increases the wall hanging split-type air conditioner for many rooms (being the living conditions of superelevation class), with the increase increase cold storage refrigerator capacity of Room area, with resident population's the water storage capacity that increases water heater that increases.As Fig. 6-4
Four, indoor function unit brief introduction:
