摘要:
An air conditioner, in which a controller is installed separately from a plurality of indoor units and a plurality of outdoor units so that only the controller is added and conventional outdoor units are used when plural indoor units are required, thereby reducing costs due to the omission of other outdoor units. The controller determines whether or not the outdoor units are respectively operated according to a signal of a temperature sensing unit, and selectively operates the outdoor units according to a required capacity, thereby increasing the operating efficiency of the air conditioner.

An air conditioner and a method for controlling the same are disclosed herein. The air conditioner has a capillary tube equipped to a connecting tube which connects a suction pipe and a discharge pipe of a compressor and has an opening/closing valve equipped therein, thereby allowing pressure equilibrium between the suction pipe and the discharge pipe of a compressor to be maintained when the compressor stops operating, and allowing a discharge flux of the compressor to be appropriately controlled when a load is lower than a capacity of the controller under operation. As a result, the air conditioner does not require a separate bypass unit, thereby simplifying the construction of the air conditioner while minimizing the installation space thereof through omission of a separate bypass unit, leading to reduction in costs.

Disclosed herein is an air conditioner having a single oil separator mounted on a confluent discharging channel, to which are connected discharging channels provided at a plurality of compressors, and an electronic expansion valve, of which the opening level is controllable, mounted on an oil collection pipe connected to the oil separator. As a result, the number of the oil separators is decreased. Consequently, the present invention has the effect of simplifying the structure of the air conditioner and reducing the manufacturing costs of the air conditioner. Furthermore, refrigerant is bypassed by controlling the opening level of the electronic expansion valve to control the flow rate of the refrigerant. Consequently, the present invention has the effect of eliminating an additional bypassing device, and therefore, simplifying the structure of the air conditioner and the controlling method of the air conditioner.
摘要:
An air conditioner incorporates valve devices mounted in a plurality of indoor units, respectively, for allowing refrigerant discharged from an outdoor heat exchanger to be introduced into one or more indoor units that are in operation. The refrigerant is prevented from being introduced into the other indoor units that are not in use, and therefore, oil is prevented from being accumulated in the other indoor units that are not in use. Also, an appropriate amount of refrigerant is supplied to the indoor units that are in operation, and therefore, reliability and efficiency of the air conditioner are improved.

A unitary air conditioner comprises a 1-stage thermostat mounted in a room for generating an air conditioner ON/OFF signal, an indoor unit configured to operate based on a signal from the 1-stage thermostat, and a variable-capacity outdoor unit connected to the 1-stage thermostat and the indoor unit. The variable-capacity outdoor unit has variable operation stages, which are changed based on the previous operation state and the current operation state. When a unitary-capacity operation signal is inputted from the 1-stage thermostat, a start operation stage of an outdoor unit is determined based on the combination of the operation stage of the outdoor unit operated before the operation signal is inputted and the operation time in the stage, and the determined operation is performed. The 1-stage thermostat can be connected to the variable-capacity outdoor unit according to circumstances. Consequently, the present invention has the effect of accomplishing various applications and providing more pleasant air conditioned circumstances.

A method of preventing rapid on/off of a compressor in a unitary air conditioner comprises the steps of, when a unitary-capacity operation signal is inputted from a thermostat to start an outdoor unit, and a specific operation stage is continued for more than a predetermined period of time after the operation is started, changing the operation stage of the outdoor unit to an operation stage higher than the specific operation stage, and operating the outdoor unit in the changed operation stage, and, when the compressor is stopped according to a signal from the thermostat within a specific period of time after the operation stage is changed to an operation stage higher than the specific operation stage, starting the operation in the specific operation stage at the next operation, and still performing the operation in the specific operation stage although the operation state is continued for more than a predetermined period of time. Consequently, the compressor is prevented from being rapidly turned on/off, and therefore, operational reliability of the compressor is improved, and the service life of the compressor is increased.

A unitary air conditioner comprises a 1-stage thermostat for generating an operation signal for the unitary air conditioner or a stop signal for the unitary air conditioner, a 1-stage indoor unit having an indoor fan, which is rotated according the operation signal from the 1-stage thermostat, a variable-capacity outdoor unit configured to be operated according to the 1-stage thermostat, the variable-capacity outdoor unit having a compressor and an outdoor fan, the operation stage of which is changed according to the operation state of the variable-capacity outdoor unit, and an indoor fan control device for controlling the indoor according to the operation stage of the variable-capacity outdoor unit to change the operation state of the indoor fan. The 1-stage indoor unit is operated along with another unit having different stages, and variable control is accomplished, although the 1-stage indoor unit is used, so long as the indoor fan control device is added to the unitary air conditioner. Consequently, a more efficient air conditioning system is accomplished.
