Abstract

The invention discloses an energy conservation improvement of a domestic air conditioner in a refrigeration state. The domestic air conditioner is simply transformed without changing the performance and the appearance of the air conditioner, so that the air conditioner saves more energy than before. When the air conditioner is installed and transformed, an outdoor unit condenser is lower than that of an indoor evaporator. A PVC (Polyvinyl Chloride) hose pipe with equivalent length and the diameter of 0.8cm is used, one end of the hose pipe is plugged by an object, and then small holes are uniformly pierced in the end of the hose pipe. The length of the PVC hose pipe is equivalent to a cooling fin of the outdoor unit condenser. A water pipe is tied to the condenser, a condensed water outlet pipe of an indoor unit evaporator of the air conditioner is connected with the outdoor unit condenser, the condensed water is scattered to the condenser so that the condensed water is evaporated from the condenser to take away heat on the condenser and help the condenser of the air conditioner dissipate heat. The better heat dissipation effect of the outdoor unit condenser of the air conditioner, the better refrigeration effect of the indoor unit evaporator; and when the indoor temperature is invariable, the heat dissipation effect of an outdoor condenser is better, and the domestic air conditioner saves more energy.

Description

The reducing energy consumption of domestic air conditioning under refrigerating state

One: technical field

Two: technical background:

On the basis that does not change heat pump performance and outward appearance, simply transform, make air-conditioning than more energy-conservation before transforming.

Three: summary of the invention (specification :)

1: the analysis of the principle of air-conditioning

(1) on existing basis, air-conditioning is transformed, made the more energy-conservation of air-conditioning change.At first to analyze the air conditioner refrigerating principle:

Split-type air conditioner is divided into indoor set and off-premises station.Accompanying drawing 1:

(2). the former refrigeration principle of air-conditioning

After the air-conditioner energising, the low-pressure steam of the refrigeration system inner refrigerant machine that is compressed sucks also and drains into condenser behind the boil down to high steam.Simultaneously the outdoor air that sucks of the aerofoil fan condenser of flowing through is taken away the cold-producing medium liberated heat, makes high pressure refrigerant vapor be condensed into highly pressurised liquid.Spray into evaporimeter behind highly pressurised liquid process filter, the throttle mechanism, and under corresponding low pressure, evaporating, the heat around drawing.Simultaneously axial-flow fan constantly gets between the fin of evaporimeter air to carry out heat exchange, and is sent to the air that turns cold after the heat release indoor.So room air constantly circulates, and reaches the purpose that reduces temperature.

(3.) conclusion

Air-conditioning is under refrigerating state, and the outdoor condenser radiating effect is good more, and the refrigeration of its evaporimeter is just good more.

Under the certain situation of indoor temperature, the good more air-conditioning of outdoor condenser radiating effect is also just energy-conservation more.

(4). modification scheme:

1.. the height of air-conditioning outdoor condenser when transformation is installed is lower than indoor machine evaporation.

2.. get an appearance and work as, the PVC flexible pipe that diameter is 0.8 centimetre, of pipe with thing stifled on, then at pipe pricks duck eye uniformly.The fin of length and outdoor condenser is suitable.Tie up water pipe on condenser, aperture down.

3.. couple together the condensed water outlet pipe of air conditioner indoor unit evaporator and the condenser of off-premises station, spread condensed water on the condenser, condensed water is evaporated on condenser; The principle of taking away the heat on the condenser; The heat radiation of help air-conditioning condenser, thus the radiating effect of raising outdoor condenser is strengthened the heat-sinking capability of air-conditioning greatly; The good heat dissipation effect of outdoor condenser; The indoor machine evaporation refrigeration is all right, and under the certain situation of indoor temperature, the good more air-conditioning of the radiating effect of outdoor condenser is also just energy-conservation more.

Five: the specific embodiment

1: concrete steps

(1). open condenser for outdoor unit of air conditioner, the osculum respectively opening a correspondence on a side of air-conditioning condenser and the lid polishes flat opening part, prevents to hurt water pipe; The also available suction pipe that we use always cuts suction pipe, then centering on the suction pipe that cuts around the Air conditioner box incision.Accompanying drawing: 2, accompanying drawing 3:

(2). get an appearance and work as, the PVC flexible pipe that diameter is 0.8 centimetre, of pipe with thing stifled on, then at pipe pricks duck eye uniformly.(hole is too not little, looks the model size of machine and decides.If the too little drain discharge in hole is too big, can cause impeded drainage, water pipe ponding can damage indoor machine evaporation too much) fin of length and outdoor condenser is suitable.Accompanying drawing 4:

(3). tie up water pipe on condenser, aperture is down.(make things convenient for condensed water outside aperture discharge currents to condenser) accompanying drawing: 5 build lid at last.Accompanying drawing: 6, accompanying drawing 7

Couple together outer water pipe with the drainpipe on the air conditioner indoor unit evaporator after finishing.

(4). when starting of air conditioner under refrigerating state, the condensed water on the indoor evaporator of air-conditioning can pass through the outside draining of drainpipe, condensed water is spread across on the condenser of off-premises station through drainpipe smoothly uniformly; At this moment the air exhauster on the condenser is lived outer air draft; Wind passes condenser, makes condensed water under the effect of air exhauster airflow, on condenser, evaporates; Take away the heat on the condenser, help the condenser heat radiation.

If air conditioner condensate water does not evaporate on the condenser of off-premises station, the hole that the condensed water that does not evaporate can turn round and look at the cabinet bottom discharges.

2. improvement cost: only need a PVC flexible pipe, 1 meter/unit.Buying in batch could be more cheap!

3. weak point: since the condensed water time toward the condenser of off-premises station on, spread water, may cause outdoor condenser generation corrosion, mechanical breakdown may take place, in the service life of reduction air-conditioning, may bring potential safety hazard.

4: solution: because the outside work of air conditioning chamber's external condenser extended immobilization is kept away unavoidable daily exposing to the sun and rain.Therefore air-conditioning is when dispatching from the factory, and producer has just considered this problem, on air-conditioner outdoor unit, has done rust preventing.

Through improved air-conditioning, on the outdoor condenser of frequentation, spread water, in order to prevent corrosion,, prevent corrosion so need do regular inspection, maintenance, maintenance and rust cleaning work to condenser for outdoor unit of air conditioner.

5: instance: if a people dries below normal fan; Can feel a chill; If people does not also dry the water on the health in the intact bath of Xian just, stand in equally and dry below the fan, it is colder that the people can feel; This is because fan at the water that dries up on the person, makes water evaporation time on one's body also taken away the heat on the person.

Sprinkle condensed water on air conditioning chamber's external condenser, help the air-conditioning condenser heat radiation, also just be to use this principle, reach energy saving purposes.

6. sum up: this scheme is with low cost, and convenient material benefit does not promptly influence the air-conditioning outward appearance, can not carry out big change to air-conditioning yet, can reach energy-saving and cost-reducing purpose again.Accompanying drawing: 6, accompanying drawing 7.
