Abstract
The utility model relates to an energy saving refrigeration system used in the splitting type air conditioner, which is characterized in that a subcooler and a precooler are additionally arranged on the refrigeration system of the present splitting type air conditioner. The subcooler is arranged at the outlet of a condenser; the precooler is arranged at the exhaust port of a compressor; and the subcooler and the precooler are communicated with a water-containing plate of an indoor unit by means of connecting pipelines so that low-temperature condensed water can exchange heat with refrigerant twice when the low-temperature condensed water is discharged, and thus the undercooling of the refrigerant can be enlarged and the condensing pressure can be lowered. Thus, the energy efficiency ratio of the whole refrigeration system is improved to efficiently save energy.
Description
The utility model relates to a kind of energy-saving refrigeration system that is used for detachable air conditioner, and it mainly is applicable to the detachable air conditioner that uses in summer high temperature high humidity area.
The basic refrigeration system of existing detachable air conditioner as shown in Figure 1 and Figure 2, Fig. 1 is the single cold type refrigeration system, Fig. 2 is the cold-warm type refrigeration system, its basic functional principle is: by the HTHP gaseous state refrigeration working medium of compressor 1 discharge, cooling through condenser 2 becomes the high-pressure liquid refrigeration working medium, the high-pressure liquid refrigeration working medium is heat absorption evaporation in evaporimeter 4 after restricting element 3 throttling step-downs, become low-temp low-pressure gaseous state refrigeration working medium, sucked by compressor 1 subsequently, again be compressed into the gaseous state refrigeration working medium of HTHP, thereby finish kind of refrigeration cycle.In refrigeration system continuous firing process, the airborne steam that is cooled off by evaporimeter can condense into water and fall into drip tray 5, and is discharged from outdoor.When air-conditioner is worked under hot and humid outdoor environment, can produce a large amount of low-temperature condensates, and the seen refrigeration system that detachable air conditioner adopted is not all recycled the energy of these low-temperature condensates at present, but directly emits, and causes energy waste.
The purpose of this utility model is the above-mentioned deficiency that overcomes existing detachable air conditioner refrigeration system, provides a kind of simple in structure, reasonable in design, and can fully recycle the energy-saving refrigeration system that is used for detachable air conditioner of low-temperature condensate energy.
The purpose that the utility model proposed can be achieved through the following technical solutions: both set up two heat exchangers in existing detachable air conditioner refrigeration system, one is positioned at the condensator outlet place, be called subcooler, one is positioned at the compressor outlet place, be called forecooler, and be connected with drain pan of indoor machine, like this low-temperature condensate elder generation process subcooler of discharging by drip tray by connecting line, pass through forecooler then, with the abundant heat exchange of refrigeration working medium after again outside the drain chamber.
The beneficial effects of the utility model are, owing in air-conditioner refrigerating system, set up forecooler and subcooler, thereby can make full use of the energy of low-temperature condensate, increase the degree of supercooling of refrigeration working medium, further reduce condensing pressure, and then the Energy Efficiency Ratio of raising air-conditioner actual condition, reach energy-efficient purpose.And the utility model is simple in structure, when doing product structure design, subcooler and forecooler all can be arranged in the body of outdoor machine of body-separated air-conditioner, and need not to increase the individual member of equipment and extra installment work.
Description of drawings is as follows:
Fig. 1 is existing single cold type detachable air conditioner refrigerant system configurations schematic diagram.
Fig. 2 is existing cold-warm type detachable air conditioner refrigerant system configurations schematic diagram.
Fig. 3 is the structural representation that the utility model is applied to the single cold type detachable air conditioner.
Fig. 4 is the structural representation that the utility model is applied to the cold-warm type detachable air conditioner.
1. compressors among the figure, 2. condenser, 3. restricting element, 4. evaporimeter, 5. drip tray, 6. cross valve, 7. subcooler, 8. forecooler.
Following the utility model will be further described in conjunction with the accompanying drawings and by embodiment.
Referring to Fig. 3, Fig. 4, the utility model mainly contains compressor 1, condenser 2, restricting element 3, evaporimeter 4, drip tray 5, cross valve 6, subcooler 7, forecooler 8 is formed, and wherein subcooler 6 is arranged at the exit of condenser 2, and forecooler 8 is arranged at the exit of compressor 1.Communicate with each other by connecting line compressor 1, condenser 2, restricting element 3, evaporimeter 4, constitute the circulation canal of refrigeration working medium, and drip tray 5, subcooler 7, forecooler 8 have constituted the energy recovery approach of low-temperature condensate by connecting line.
When system works, low-temperature condensate relies on the gravity effect to enter subcooler 7 through drip tray 5 earlier, because the temperature of condensate water is far below the temperature that is flowed to the high-pressure liquid refrigeration working medium of restricting element 3 by condenser 2, therefore low-temperature condensate can be in subcooler 7 and the refrigeration working medium heat exchange, thereby further reduce the temperature of refrigeration working medium, increase degree of supercooling, improve the refrigerating capacity of unit mass refrigeration working medium.Enter forecooler 8 again through the condensate water after 7 heat exchange of subcooler, because the temperature through the condensate water after subcooler 8 heat exchange still is lower than the temperature to the HTHP gaseous state refrigeration working medium of condenser 2 by compressor 1 row, therefore the refrigeration working medium heat exchange once more that can in forecooler 8, discharge of condensate water with compressor 1, thereby reduce the temperature of the refrigeration working medium that enters condenser 2, and then the reduction condensing pressure, the work energy consumption of minimizing compressor 1.Can drain into outdoor by discharge tube through the condensate water behind forecooler 8 secondary heat exchanges.
Need explanation a bit, because the power of condensate water is to utilize gravity, therefore adopt detachable air conditioner of the present utility model, the absolute altitude of its drain pan of indoor machine 5 discharge outlet will be higher than the absolute altitude of subcooler 7 water inlets, and the absolute altitude of subcooler 7 delivery ports will be higher than the absolute altitude of the water inlet of forecooler 8.
