Problems solved by technology

In the cooling season, the outdoor ambient temperature is generally above 30 degrees, while the condensation temperature is generally more than 50 degrees, and the temperature difference is only more than 20 degrees. Therefore, the heat transfer capacity is limited to a certain extent.
[0003] In the prior art, in order to solve this problem, the condensed water is usually sprayed onto the condenser in a circular manner, and the sprayer is installed above the condenser. While the air is cooling, the condensed water is evaporated and the air is released with the condenser. The discharge also improves the heat transfer performance of the condenser. For example, in the patent 200610036924.2, a supplementary water cooling type integral air conditioner is used, and the spray circulation system is continuously operated through the external supplementary water source, but in order to achieve this purpose, a complex circulation system is required , including water pumps, throttling components, water tanks, etc. These components have complex structures, and consume a lot of power and water. In addition, because the cooling water adopts a recycling mode and there are no sealing measures, as time goes by, The intrusion of external impurities and the scale in the circulation system require regular maintenance and cleaning, otherwise the heat exchange efficiency will be greatly reduced, which also brings inconvenience to users

Embodiment 1

[0023] The invention provides an electricity-saving spraying device aiming at the shortcomings and deficiencies existing in the air-cooling mode of the existing air conditioner, so as to achieve the goals of water saving, electricity saving, simple structure and maintenance-free.

[0024] As shown in Figures 1 and 2: its structure is the case of a nozzle.

[0025] The electricity-saving spraying device of an air conditioner includes: an outdoor unit 4 provided with a condenser, a nozzle 7 , a fixing bracket 5 for fixing the nozzle 7 , and a water inlet control device 6 . The water inlet control device 6 includes a controller (figure omitted), a solenoid valve 2, a water inlet pipe 3 and a water outlet pipe 1. The solenoid valve 2 is connected with the tap water pipe through the water inlet pipe 3, connected with the nozzle 7 through the water outlet pipe 1, and connected by the controller. Control the amount of water. The electromagnetic valve 2 is arranged on the top of the ...

Embodiment 2

[0031] This embodiment is similar to Embodiment 1, the difference is that, as shown in Figure 4, it is the structure of a plurality of shower heads and the structure of the fixing frame of this embodiment, here the number of 7 nozzles is five, according to the surface of the outdoor unit 4 The area is evenly arranged, and the connection lines of the four outer nozzles form a square, the fifth nozzle is located on the diagonal of the square, and its projection on the surface of the outdoor unit 4 is located in the center. The arrangement of the four nozzles in the periphery makes the spray area continuous on the surface of the outdoor unit, and the cone-shaped spray of the outermost nozzles covers the square surface of the outdoor unit with the largest area in the spraying area on the surface of the outdoor unit.

[0032] Tests have proved that the use of the power-saving spray device can reduce the exhaust temperature of the outdoor unit by more than 3 degrees, which not only s...

Embodiment 3

[0034] The present invention also provides an operation mode of an electricity-saving spraying device, comprising the following steps:

[0035] A. Start refrigeration;

[0036] B. During the set time of refrigeration just after starting up, usually a few minutes, the temperature of the condenser has not yet risen, so do not spray water for a few minutes after the compressor is started, until the temperature of the condenser rises to a certain level, control According to its actual situation, the solenoid valve is controlled to open, the water flow enters the nozzle through the water inlet pipe 3 and the water outlet pipe 1, and starts to spray. At this time, the spray sprayed on the outdoor unit 4 meets the condenser with a higher temperature for heat exchange At the same time, it is also continuously evaporated, which also plays a role in heat exchange.

[0037] C. The water inlet control device controls the water sprayed on the condenser by the nozzle to evaporate at any ti...

Abstract

The invention discloses a power-saving spraying device for an air conditioner, which comprises an outdoor unit provided with a condenser, a plurality of nozzles, and a water inlet control device, wherein the water inlet control device is arranged outside the outdoor unit, is respectively connected with a water source and the nozzles, and is used for controlling the spraying amount of the nozzles; the nozzles are arranged on the outside of at least one surface at the periphery of the outdoor unit, and the spraying direction of the nozzles faces the outdoor unit; and the water inlet control device controls water sprayed by the nozzles onto the condenser at any time to evaporate completely. The invention also provides an operating method for the power-saving spraying device; and the spraying is carried out after the cooling is started for a period of time, and more energy and power are saved. The power-saving spraying device for the air conditioner has the advantages of high heat exchange efficiency, low power consumption, simple structure and no maintenance.

Description

technical field [0001] The invention relates to the technical field of energy-saving devices for air conditioners, in particular to an electricity-saving spraying device for air conditioners. Background technique [0002] The heat transfer performance of the condenser of the air conditioner greatly affects the cooling capacity and energy efficiency of the air conditioner. Household air conditioners generally use air-cooled heat exchange, that is, a fan blows the condenser to perform heat exchange. In the cooling season, the outdoor ambient temperature is generally above 30 degrees, while the condensation temperature is generally more than 50 degrees, and the temperature difference is only more than 20 degrees, so the heat transfer capacity is limited to a certain extent. [0003] In the prior art, in order to solve this problem, the condensed water is usually sprayed onto the condenser in a circular manner, and the sprayer is installed above the condenser. While the air is ...
