Embodiment 1

[0049] This embodiment provides a cold recovery method, which includes: collecting condensed water generated by the air conditioner in cooling mode; judging whether the air conditioner meets the preset conditions for cold wind mode operation, and closing the chamber when the air conditioner meets the cold wind mode operation preset conditions; The outer compressor uses the condensed water generated during the operation of the air conditioner as a cold source to cool the indoor environment.

[0050] During the operation of the air conditioner, user comfort is given priority, and power consumption and energy saving are secondly considered. Therefore, when the air conditioner meets the operating conditions of the cold air mode, the condensed water is fully utilized to achieve cooling and energy saving effects.

[0051] Preferably, in the cold wind mode, the condensed water is sprayed onto the evaporator, so that part of the condensed water is blown into the indoor environment alon...

Embodiment 2

[0055] Such as Figure 2-4 As shown, this embodiment provides an air conditioner, which includes: a water tank, a spray device and a controller, wherein the water tank is used to collect condensed water generated during the operation of the air conditioner; the spray device is used to extract the condensed water in the water tank to spray On the evaporator of the shower air conditioner; the controller is used to implement the cooling recovery method in Example 1.

[0056] Preferably, the air conditioner includes a bottom case 1 , and the spray device includes a spray pump 2 , a water tank 3 and a spray head 6 . The water tank 3 is mainly used to collect and store the condensed water generated by the normal air conditioner operation, and the spray pump 2 is used to pump out the condensed water in the water tank 3 and spray it out from the nozzle 6 under pressure. When the preset operating conditions of the cold air mode are reached, the outdoor compressor is turned off, and on...

Abstract

The invention provides a cooling capacity recovery method, an air-conditioning refrigeration energy-saving control method and an air conditioner, and relates to the technical field of air conditioning. The cooling capacity recovery method collects condensed water generated by the air conditioner in the cooling mode operation; and judges whether the air conditioner meets the cold air mode operation preset condition, when the air conditioner satisfies the preset conditions for running in the cold air mode, the outdoor compressor is turned off, and the condensed water generated during the operation of the air conditioner is used as a cooling source to cool the indoor environment. Reusing the internal unit of the air conditioner will produce a large amount of condensed water during the cooling process. The cross-flow fan blade of the internal unit can be opened separately, which has an effect similar to that of a cooling fan, which changes the traditional direct discharge method and improves the utilization rate of condensed water. .

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cold recovery method, an air conditioner refrigeration energy saving control method and an air conditioner. Background technique [0002] During the cooling operation of the existing air conditioner, the air near the evaporator meets the cooler fins of the evaporator, and the air releases heat to generate condensed water. On the one hand, the condensed water takes away part of the cooling capacity of the air conditioner, reducing the cooling efficiency. The risk of water leakage and dripping from the internal unit. The generated condensed water often flows into the water receiving tray and is discharged outdoors, and the condensed water is not utilized or fully utilized. In the prior art, a scheme of utilizing the condensed water generated on the evaporator of the air conditioner is proposed, which circulates the condensed water back to the fins of the evaporator, and...
