摘要:
Provided are an outdoor unit of an air conditioner, and an operation method thereof. The outdoor unit of the air conditioner includes: a case including an outlet; and an outlet door installed at the case to open/close the outlet, and guiding the air being discharged when opened. Thus, the air being discharge can be guided in a desired direction when the outlet is opened, and foreign substances can be prevented from flowing into the case when the outlet is closed.

Disclosed are an air conditioner and a refrigerant control method thereof. An air conditioner according to an embodiment of the invention an outdoor unit including a compressor, an outdoor heat exchanger, and a four-way valve that switches a flow passage of refrigerant, an indoor unit including an indoor heat exchanger, an indoor expansion unit disposed at a refrigerant inlet side of the indoor heat exchanger and allowing the refrigerant to be expanded during the cooling operation, an outdoor expansion unit disposed at a refrigerant inlet side of the outdoor heat exchanger and allowing the refrigerant to be expanded during the heating operation, and a control unit controlling the indoor expansion unit and the outdoor expansion unit such that the refrigerant is expanded in the indoor expansion unit during the cooling operation and the refrigerant is expanded in the outdoor expansion unit during the heating operation. Therefore, the distance between the evaporator and the expansion unit is reduced to thereby raise operating efficiency.
摘要:
A method for removing a partial overload in an air conditioner, which includes determining whether a plurality of indoor units provided in the air conditioner includes at least one indoor unit operating in an overload state; and performing a partial overload operation to increase the amount of a refrigerant introduced into a corresponding evaporator of the at least one indoor unit when the at least one indoor unit is operating in the overload state.
摘要:
A driving controlling apparatus for an air conditioner having a plurality of compressors, and a method thereof. The apparatus comprises a flow amount distribution resistor installed at an outlet of an expansion valve, for passing a certain amount of refrigerant; and a controlling unit for detecting a current load and outputting a control signal so as to introduce a certain amount of refrigerant into the flow amount distribution resistor based on a driving mode corresponding to the detected load.

摘要:
An apparatus for converting a refrigerant pipe of an air conditioner comprises: a valve housing installed at a position where respective refrigerant discharge pipes of plural compressors are put together, having a valve space portion therein, and having a first refrigerant inlet, a second refrigerant inlet, a detour refrigerant inlet, a refrigerant outlet and a bypass outlet at upper and lower portions thereof; a bypass pipe for connecting the refrigerant outlet of the valve housing to refrigerant suction pipes of the compressors so that a refrigerant discharged from each refrigerant discharge pipe of the plural compressors can be introduced to the refrigerant suction pipes of the plural compressors; an open/close valve slidably installed at the valve space portion of the valve housing so that a refrigerant discharged from the refrigerant discharge pipes can be selectively introduced into a refrigerant circulation pipe of a condenser or the bypass pipe; and an open/close valve driving means installed at the valve housing and driving the open/close valve.
摘要:
A stand-type air conditioner including a casing having at least two air discharge openings and an air suction opening, and a blower fan installed therein. Also included are at least two heat exchangers positioned adjacent to the air discharge openings, respectively, in the casing for exchanging heat with air to be discharged through the air discharge openings. Further, at least one of the air discharge openings is located at a lower portion of the casing in the vicinity of the ground for discharging air near the ground. By discharging cold air from an upper side during the cooling operation and hot air from a lower side during the heating operation, the cold air or the hot air can be evenly distributed to the room. Accordingly, uniform cooling/heating can be realized to thereby significantly increase reliability and efficiency of a product.

Disclosed are an air conditioner and a method for controlling the operation thereof. To this end, an air conditioner includes: a thermostat; a first temperature detecting means for detecting a temperature of the air sucked into an indoor heat exchanger; a second temperature detecting means for detecting an outdoor temperature; a control means for generating a signal for controlling the operation of an indoor fan on the basis of an indoor temperature detected by the thermostat, an air temperature detected by the first temperature detecting means and an outdoor temperature detected by the second detecting means; and an indoor fan rotated according to a signal generated by the control means.
摘要:
An apparatus for controlling an air-conditioner for generating a first control signal for controlling an air-conditioner in a minimum operation mode or a second control signal for controlling the air-conditioner for controlling the air-conditioner in a maximum operation mode based on a room temperature and a desired temperature previously set by a user, and controlling an indoor fan and an outdoor fan and compressing capacity of compressors of the air-conditioner in multistage based on the first or second control signal and the outdoor temperature. By controlling compressing capacity of the air-conditioner, a rotation speed of an outdoor fan and an indoor fan in multistage based on an outdoor temperature and control signals for controlling a room temperature, a load coping capability can be enhanced.
