Embodiment Construction

[0030] Preferred embodiments of the present invention will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0031] now refer to Figure 4 with Figure 5 A preferred embodiment of a method for controlling a solenoid valve of an air conditioner to reduce power consumption of the air conditioner will be described. Here, since the compressor and the solenoid valve according to the present invention have the same structure as the conventional compressor and solenoid valve, reference numerals of the compressor and the solenoid valve are omitted here.

[0032] Figure 4 A flowchart showing a method for controlling a solenoid valve of an air conditioner according to an embodiment of the present invention. Here, solenoid valves are respectively connected to inlet and outlet conduits of the small-capacity compressor and the large-capacity compressor to balance the internal pressures of the small-capacity compressor and the large-capacity c...

Abstract

Disclosed is a method for controlling a solenoid valve of an air-conditioner capable of reducing power consumption of an air-conditioner. To this end, in the method for controlling the solenoid valve of the air-conditioner, when at least one compressor of the air-conditioner temporarily stops operating, power is applied to a solenoid valve connected to the compressor for a preset time.

Description

technical field [0001] The present invention relates to an air-conditioning device, and in particular to a method for controlling a solenoid valve of an air-conditioning device. Background technique [0002] In general, an air conditioner cools hot air in a room or heats cold air in a room. Refer below figure 1 A structure of an air conditioner having two compressors according to a conventional technique will be described. Here, the two compressors are selectively operated depending on the cooling load or the heating load of the room. [0003] figure 1 is a block diagram showing the structure of an air conditioner with two compressors according to the prior art. [0004] As shown in the figure, the air conditioner includes: a first compressor 11 and a second compressor 12, the first compressor 11 and the second compressor 12 have different compression capacities and compress the refrigerant into a high-temperature and high-pressure gaseous state refrigerant; the outdoor...
