Abstract
Disclosed herein is a heat exchanger for use in an air conditioner. The heat exchanger is provided with a path switching unit at a tube that forms a refrigerant path. The path switching unit is used to switch the flow path of a refrigerant passing through the tube in accordance with a cooling or heating load, thereby regulating the flow rate of the refrigerant. The use of the path switching unit has the effect of achieving an effective control of cooling or heating capacity thereof based on an external load.
Claims20
A heat exchanger comprising:
- a refrigerant path defined inside a heat exchanger body for the passage of a refrigerant;
- and
- at least one path switching unit provided at the refrigerant path to switch the flow path of the refrigerant, in order to regulate the flow rate of the refrigerant passing through the refrigerant path.
An air conditioner using a heat exchanger, comprising:
- a compressor to compress a refrigerant into a high-temperature and high-pressure state;
- an indoor heat exchanger to perform a heat exchange between the refrigerant, discharged from the compressor, and indoor air;
- an expansion member to expand the refrigerant discharged from the indoor heat exchanger;
- and an outdoor heat exchanger to perform a heat exchange between the refrigerant discharged from the expansion member and outside air,
- wherein each of the indoor heat exchanger and the outdoor heat exchanger comprises:
- a refrigerant path defined inside a heat exchanger body for the passage of the refrigerant;
- and
- at least one path switching unit provided at the refrigerant path to switch the flow path of the refrigerant, in order to regulate the flow rate of the refrigerant passing through the refrigerant path.
