Abstract:
A heat pipe provided with an outdoor unit having a compressor and an outdoor heat exchanger, a plurality of indoor units provided to be driven at a cooling mode or a heating mode. an indoor unit mode control unit to control the each of the plurality of indoor units to be driven at a cooling mode or a heating mode. and a flow path conversion apparatus connected to a first refrigerant pipe and a second refrigerant pipe connected from the outdoor unit, connected to a high pressure gas pipe and a low pressure gas pipe connected to the indoor unit mode controlling unit, and configured to change the flow path of a refrigerant by selectively connect all or some of the first refrigerant pipe, the second refrigerant pipe, the high pressure gas pipe, and the low pressure gas pipe according to the mode at which the indoor units are driven.
Abstract:
Disclosed herein is an air conditioner. The air conditioner includes an outdoor unit having a compressor, an outdoor heat exchanger, and a flowpath switching valve disposed on a refrigerant flowpath between the compressor and the outdoor heat exchanger, a plurality of indoor units configured to operate in a cooling mode or in a heating mode, a mode controller configured to selectively guide refrigerant received from the outdoor unit to the plurality of indoor units. The mode controller guiding the refrigerant through one or more of: a first refrigerant pipe extending from the flowpath switching valve to the mode control unit, a second refrigerant pipe extending from the flowpath switching valve and diverging to the outdoor heat exchanger, and to the mode control unit, and a third refrigerant pipe extending from the outdoor heat exchanger to the mode controller.
Abstract:
An asynchronous receiver-transmitter circuit which compensates for an output signal so as to be the same as an input signal upon an asynchronous communication, and a washing machine including the same. The asynchronous receiver-transmitter circuit includes a photo-coupler turned on by an applied input signal to provide an output signal; and a compensation part configured to compensate for a time required while the output signal arrives at a high value to correspond to a time required while the output signal arrives at a low value.
