PROBLEM TO BE SOLVED: To provide heat carrying equipment which suppress lowering of the efficiency of a heat exchanger. SOLUTION: The heat carrying equipment has a closed-loop circulation circuit which connects a rotation speed variable type liquid pump 1, an evaporator 3 and the heat exchanger 7 sequentially and is filled with a refrigerant. The equipment is provided with detecting means 31 and 33 for detecting a supercooling degree at an inlet of the liquid pump 1 and a control means 41 for controlling the speed of rotation of the liquid pump 1 according to the supercooling degree detected by these detecting means.
