<p>PROBLEM TO BE SOLVED: To prevent an air conditioner from being made in large and a structure from being complicated at a time of constituting the air conditioner by a heat pump device for which an elastic body such as rubber is not used.SOLUTION: A cooling/heating module for cooling or heating air includes: cooling/heating units (20a, 20b) each having multiple thermally strained materials (21); and an actuator (22) applying a tension to the thermally strained materials (21), and the actuator (22) includes: a fixed portion (40) having an attachment surface to which one end of each of the thermally strained materials (21) is fixed; and movable portions (41a, 41b) disposed opposite to the fixed portion (40) and having an attachment surface to which the other end of each of the thermally strained materials (21) is fixed; and displacement mechanisms (46, 47, 51, 52) causing the movable portions (41a, 41b) to reciprocate so as to change a distance between the movable portions (41a, 41b) and the fixed portion (40) while the attachment surface of the movable portions (41a, 41b) and the attachment surface of the fixed portion (40) are kept in parallel.</p> |
