Description

The invention relates to air conditioning, namely to the design of a household air conditioner.

Known household air conditioners with compression refrigeration machine, which can be limited to move in the room to be cooled. In such air conditioners, the heat generated is removed with water vapor through a flexible hose l.

The disadvantages of an air conditioner are the presence of vibration and noise during operation and difficulty in operation.

Household air conditioners are also known that contain a casing with a bottom and a lid and an absorption chiller located therein with a condenser, an absorber and a binary mixture heat exchanger, equipped with a pump and a fan 2.

The disadvantage of these air conditioners is the lack of efficiency, which is due to the fact that during the operation of the refrigerating machine, all the energy released during its operation in the form of heat is emitted, i.e. not used.

The aim of the invention is to increase the economy by utilizing the heat generated.

This goal is achieved by the fact that the bottom and cover of the casing have double walls with the formation, respectively, of the lower and upper tanks, of which the lower one is filled with water and forms a closed loop with the cooling cavity of the absorber, equipped with a water pump, the discharge line of which

condenser and heat exchanger of the binary mixture, connected to the upper tank. In this case, the chiller pump and the water pump are located on the same shaft and have a common drive with a fan.

The drawing shows a proposed household air conditioner containing an absorption refrigerating machine with a pump 1 located on the same shaft as the water pump 2, and a heat exchanger 3, as well as a bottom and a lid having double walls with the formation of a lower 4 and upper

and the discharge through the heat exchanger 3 to the generator 8. The lower tank 4 forms with the cooling cavity the absorber 7 a closed loop. A water pump 2 is connected to this circuit; it is connected to the lower tank 4 by a suction line, and the discharge pump is connected to the absorber 7 and through the cooling cavity of the condenser 9 and the heat exchanger 10 of the binary mixture to the upper tank 5. The generator 8 is equipped with the first 11 and second 12 steps an electric heater and a thermostat 13, electrically connected via a relay 14 to the second stage 12 of the electric heater. The chiller contains choke 15 for the lean mixture and choke 16 for the component, made in the capillary tube. The upper tank 5 has niches 17 with lids and a drain valve 18. Between the heat exchanger 3 and condenser 9, a water regulator 19 is installed. The air conditioner is equipped with a thermostat regulator 20, which turns it off when the room temperature drops below the set one, and the fan 21, which has pumps 1 and 2, a common drive 22, for pumping air through the evaporator 23 of the refrigerating machine. The system is started by turning on the air conditioner in the network. At start-up, the stages 11 and 12 of the electric heater and the common drive 22 are turned on in parallel. The second stage 12 of the electric heater serves to accelerate the steady-state process of operation. Upon reaching the required temperature of the saturated mixture in the generator 8, the thermostat 13, through the relay 14, turns off the stage 12. From this point on, the starting acceleration of the system ends. Its further work is as follows. The air from the room is taken in through the left decorative slot by the fan 21 and the passage through the annulus of the refrigeration evaporator 23, is cleared of dust and returned to the room. In order to maintain the evaporator 23's constantly cold walls, the low-boiling component boils in its inner tube cavity under reduced pressure, its resulting vapors are sucked and absorbed by the lean mixture in the absorber 7 under the same pressure, and the binary mixture becomes saturated. In this process, active heat generation takes place. The resulting saturated mixture is pumped by pump 1 through heat exchanger 3, where it is sequentially preheated, to generator 8, where the pressure is higher and where it is drained by the first step 11 of the electric heater for further separation into the lean mixture returned by the difference pressure through the heat exchanger 3 and the throttle 15 to the absorber 7, and to the evaporated component, then sent to the condenser 9. In the latter, the component is cooled with water and high-pressure, is liquefied, and then follows under the spacing pressure to the throttle 16. The choked liquid component feeds the evaporator 23 to maintain the continuity of the boiling process. To maintain the continuity of the process of absorption of the component by the mixture in the absorber 7 and condensation in the condenser 9, heat is removed from them by taking the section 2 of the cold water from the lower tank 4 and pumping it through the cooling cavities of the absorber 7 to the condenser 9. warm condensation water should be in the heat exchanger 3. Here the water carries out the first stage of preheating the saturated mixture entering the generator 8. Then the water, being only slightly cooled by the saturated mixture in the heat The exchanger enters the upper tank 5, having a sufficiently high temperature. The second stage of preheating the saturated mixture is completed depleted in the same heat exchanger 3. Because in the preheating stage of the saturated mixture in the heat exchanger 3, heat is supplied significantly less than "it is removed from the absorber 7 and the condenser 9, respectively, and the filling of the upper tank 5 is less than the circulation of cooling water through the absorber 7. But, since both flow rates are interconnected to the pump section 2, during operation, water is pumped from the lower tank 4 to the upper tank 5 and is heated so that ntsu work it is created some of its stock. The water regulator 19 in operation stabilizes the process of condensation of the component and the distribution of water between the condenser 9 and the absorber 7 as its temperature increases. It can be installed and adjusted on time. The proposed household air conditioner combines the functions of two electrical units: an air conditioner and a water heater, while all the energy supplied to the device is used rationally. Claim 1.
