A dehumidifier includes a body having an inlet for suctioning air and an outlet for discharging air; a compressor, disposed at the body, for compressing a refrigerant; a condenser for condensing the refrigerant compressed from the compressor; an expander for expanding the refrigerant condensed from the condenser; an evaporator, disposed at upstream of the condenser according to the flow direction of air, for evaporating the refrigerant expanded from the expander; a condensate water tank to store condensate water condensed from the evaporator; and a condensate water pipe, connected to the condensate water tank, for flowing the condensate water to be heat-exchanged with the refrigerant compressed from the compressor.

Dehumidifier

A heat pump includes a first cycle device and a second cycle device. The first cycle device is connected such that, in a heating operation, a first refrigerant is circulated in an order of a first compressor, a 4-way valve, a first heat exchanger, a second heat exchanger, a first expansion mechanism, a third heat exchanger, the 4-way valve, and the first compressor, and such that, in a cooling operation, the first refrigerant is circulated in an order of the first compressor, the 4-way valve, the third heat exchanger, the first expansion mechanism, the second heat exchanger, the first heat exchanger, the 4-way valve, and the first compressor. The second cycle device is connected such that a second refrigerant is circulated in an order of a second compressor, a fourth heat exchanger, a second expansion mechanism, the second heat exchanger, and the second compressor.

Heat pump

A dehumidifier is provided that may include a main body, a compressor provided within the main body to compress a refrigerant, a plurality of heat exchangers provided within the main body to condense the refrigerant compressed in the compressor or to evaporate the refrigerant, a first fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers and having subsequently undergone heat exchange with the refrigerant condensed in the plurality of heat exchangers, out of the main body, a mode switch to perform switching between operating modes, including a cooling mode and a dehumidification mode, and a second fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers in the cooling mode, out of the main body.

A hot water supply apparatus for combined use with an air conditioner is provided that may include an indoor unit having an indoor heat exchanger to heat exchange a first refrigerant with indoor air, and a cascade hot water heater connected to the indoor unit to receive the first refrigerant and to provide a second refrigerant to heat water. The cascade hot water heater may perform a heat exchange between the first refrigerant and a second refrigerant. The cascade hot water heater may include a capacity variable compressor to limit a maximum flowing amount of the second refrigerant and increase a flowing amount of the first refrigerant to flow to the indoor unit.

Heat pump supply apparatus having a combined use with an air conditioner

A heat pump type water heating apparatus is provided that includes a refrigeration cycle circuit having a first refrigerant and water heat exchanger to perform a heat exchange between a first refrigerant and water, and a first refrigerant and second refrigerant heat exchanger to perform a heat exchange between the first refrigerant and a second refrigerant. The heat pump type water heating apparatus may also include a cascade circuit having the first refrigerant and second refrigerant heat exchanger to operate jointly with the refrigeration cycle circuit, the cascade circuit also having a second refrigerant and water heat exchanger to perform a heat exchange between the second refrigerant and water, and a water heating channel connected to the first refrigerant and water heat exchanger and the second refrigerant and water heat exchanger so water passes through the first refrigerant and water heat exchanger and then through the second refrigerant and water heat exchanger.
