Description
Technical field
The present invention relates to a kind of all-in-one machine integrated with heat and cold sources.
Background technology
Heavy construction such as modern hospital, hotel with can characteristics be that cooling amount, heating load are big, the Cooling and Heat Source feeding medium mainly is chilled water and hot water (water temperature is not high).User side disperse and have the control of two classes require different, difference is big.
Traditional low-temperature receiver, the thermal source of buildings such as existing hospital, hotel split, and as shown in Figure 1, freezing unit is emitted considerable waste heat on the one hand, and practical again on the one hand a large amount of energy burn steam.Although people improve the efficient of refrigeration unit and boiler by fair means or foul, and reclaim these used heat, obtained certain achievement, do not solve big basic of hospital's energy consumption.Therefore energy-conservation key should be the reasonable coupling of Cooling and Heat Source, improves efficiency of energy utilization, rather than controls consumption, and especially can not reduce environment control quality.The facility system design concept of present hospital, various function section office (portion) design respectively in the institute.With various function section office (portion) particular space is the control target, and low-temperature receiver, thermal source are realized to suitable hot and cold media (as air, hot and cold water, the steam etc.) amount of control target input, also produce used heat, waste water, waste gas simultaneously.Cold media mainly uses for medical treatment in summer section office air-conditioning, and thermal medium is mainly supplied steam and hot water, is used for sterilization, domestic hot-water, medical heat supply, winter heating etc.In low-temperature receiver cooling and heat supply, consume electricity or gas equal energy source, and produced corresponding used heat, useless cold, be discharged in the external environment with the form of air draft, condensed water or sanitary sewage.
The energy-conservation theory of tradition is again the conservation measures that each specialty (technology, building, power, plumbing etc.) proposes from own angle, can't form aggregate measures, even adopt state-of-the-art technology, use equipment the most efficiently, improve system's energy consumption efficiency again, the final energy consumption that reduces, the waste heat discharge amount of minimizing still is limited, the crux of this just present hospital high energy consumption.
A kind of " energy lift machine " appearred afterwards, so-called " energy lift machine " only with unit from as control volume, to keep self cold and hot amount balance, in case the heat imbalance, unit just has constantly discharging of used heat (cold).Particularly in summer, when " energy lift machine " when being converted to main cooling, its efficient (COP) is lower than general single cooler group, equally in the winter time, when " energy lift machine " is converted to main heat supply, when temperature dropped to a certain extent, its efficient is reduced to even is lower than electrical heating, and is in use very big to the waste of energy consumption.
From the above, the unit that generally uses cooling and heat supply simultaneously at present, and in use energy consumption is bigger, and also bigger to the pollution of environment.
Summary of the invention
The object of the invention provides a kind of all-in-one machine integrated with heat and cold sources, uses this system, cooling and heat supply simultaneously, energy utilization rate height.
For achieving the above object, the technical solution used in the present invention is: a kind of all-in-one machine integrated with heat and cold sources, comprise a compressor, the high-pressure outlet end of described compressor is connected with condenser, the port of export of described condenser is connected with the entrance point of throttling arrangement, the port of export of described throttling arrangement is connected with evaporimeter, the port of export of described evaporimeter is connected with the low pressure inlet end of described compressor, described condenser is made of water-cooled condenser and air-cooled condenser parallel connection, described evaporimeter is made of water-cooled evaporimeter and air-cooled evaporimeter parallel connection, one group of fluid passage of described water-cooled condenser is connected with described throttling arrangement, another group fluid passage is connected with first EGR, the one group of fluid passage and the described compressor low pressure inlet end of described water-cooled evaporimeter, another group fluid passage is connected with second EGR.
In the technique scheme, described compressor is a prior art, its effect is the gas that sucks low-temp low-pressure, after compression, discharge the gas of HTHP, described condenser is the device that gas is become liquid, and described evaporimeter is the device that liquid is become gas, described throttling arrangement can be an electric expansion valve, and its effect is that highly pressurised liquid is transformed into low pressure liquid.This device in use, the high-pressure outlet end of compressor is discharged gases at high pressure, described gases at high pressure enter water-cooled condenser, after the water-cooled condenser cooling, become highly pressurised liquid, wherein one group of fluid passage makes highly pressurised liquid flow to throttling arrangement, the heat that another group fluid passage makes transition process produce is derived through EGR by hot water, supplies with air-conditioning and terminal temperature difference and uses; The highly pressurised liquid of flow throttling device changes low pressure liquid (may be gas, liquid two-phase) into through throttling arrangement, described low pressure liquid enters in the water-cooled evaporimeter, through water-cooled evaporimeter processing becoming low-pressure gas, one group of fluid passage makes low-pressure gas go in the compressor, another group fluid passage supplies with air-conditioning through EGR and terminal temperature difference uses, whole process makes and has reduced cold and hot amount balance waste heat or surplus cold discharging, thereby dropped to non-renewable energy resources consumption minimum.When not needing water-cooled condenser to work fully, the gases at high pressure part that compressor comes out is through air-cooled condenser, by air-cooled condenser gases at high pressure are condensed into highly pressurised liquid, wherein the heat of Chan Shenging directly is discharged into outdoor, highly pressurised liquid changes low pressure liquid into through throttling arrangement, enters the water-cooled evaporimeter; If the water-cooled evaporimeter need not to work fully, then the low pressure liquid of some enters air-cooled evaporimeter, becomes low-pressure gas through air-cooled evaporimeter, and the cold of generation directly is discharged to outdoor, and low-pressure gas enters compressor, continues circulation.Air-cooled condenser and air-cooled evaporimeter can not worked simultaneously.
Further technical scheme is provided with the heat supply servicing unit in described first EGR, is provided with the cooling servicing unit in second EGR.The setting of above-mentioned heat supply servicing unit and cooling servicing unit, when extreme weather, cold and hot amount in EGR is under-supply, all-in-one machine integrated with heat and cold sources and servicing unit can be used in combination, according to building in Various Seasonal, difference in functionality and efficient, adopt different combined runnings, realize best comprehensive efficiency.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention is by being connected the compressor high-pressure outlet end with condenser, condenser is connected with evaporimeter through throttling arrangement, described evaporimeter is connected with the low pressure inlet end of compressor, one group of fluid passage of described evaporimeter and condenser is connected with EGR, thereby heat supply simultaneously or cooling satisfy different instructions for uses, and whole process has reduced energy consumption as compared with the past, and reduced waste heat and surplus cold discharging, realized best comprehensive efficiency;
2. the present invention is provided with servicing unit in EGR, thereby makes all-in-one machine integrated with heat and cold sources to be used in combination with servicing unit, satisfies the instructions for use under the extreme condition;
3. the present invention is simple in structure, and the use aspect is easy to realize, is fit to promote the use of.
