Abstract

An air conditioner disclosed herein includes a cooling/heating module including a thermoelastic material and an actuator applying tension to the thermoelastic material and a switching control section selectively applying or removing tension to/from the thermoelastic material.

First claim

The invention claimed is:

1. An air conditioner comprising:
first and second cooling/heating modules each including
a thermoelastic member made of thermoelastic material,
a fixed member to which one end of the thermoelastic member is fixed, and
an actuator to which the other end of the thermoelastic member is fixed and which selectively displaces in a direction away from the fixed member and a direction toward the fixed member, the actuator being controlled to selectively apply or remove tension to/from the thermoelastic material;

a first air passage in which the first cooling/heating module is provided; and
a second air passage in which the second cooling/heating module is provided,
wherein the thermoelastic material is a wire made of a shape memory alloy, and
wherein the actuator of the first cooling/heating module and the actuator of the second cooling/heating module simultaneously displace in opposite directions with respect to each other.

2. The air conditioner of claim 1 , wherein
the air conditioner is configured to perform a cooling mode of operation in which air cooled by one of the first and second cooling/heating modules is supplied to an indoor space.

3. The air conditioner of claim 1 , wherein
the air conditioner is configured to perform a heating mode of operation in which air heated by one of the first and second cooling/heating modules is supplied to an indoor space.

4. The air conditioner of claim 1 , wherein
the air conditioner is configured to switch modes of operation from a cooling mode of operation in which air cooled by one of the first and second cooling/heating modules is supplied to an indoor space into a heating mode of operation in which air heated by the one of the first and second cooling/heating modules is supplied to the indoor space, and vice versa.

5. The air conditioner of claim 1 , wherein
the air conditioner is configured to supply room air that has passed through one of the first and second cooling/heating modules to an indoor space.

6. The air conditioner of claim 1 , wherein
the air conditioner is configured to supply outdoor air that has passed through one of the first and second cooling/heating modules to an indoor space.

7. The air conditioner of claim 1 , wherein
the actuator is controlled to adjust the quantity of heat generated by the thermoelastic material by changing the magnitude of tension applied to the thermoelastic materials.

8. The air conditioner of claim 1 , wherein the thermoelastic material is a Ti/Ni/Cu alloy.
