Title:
HEAT TRANSPORTING APPARATUS
Document Type and Number:
Japanese Patent JP3225142
Kind Code:
B2
Abstract:
PURPOSE: To provide a heat transporting apparatus which can rapidly obtain sufficient capacity at an evaporator side at the time of starting an operation, prevent wasteful operation of a pump as much as possible to reduce power cost and further suitably transport heat without increasing size of a tank.
CONSTITUTION: When a temperature of a condenser 2 is higher than a set value T2, an operation of a pump 6 is inhibited. At the time of starting an operation, when the temperature T of the condenser 2 is lowered to a set value T2 or lower, the pump is started at number of revolutions N1, a two-way valve 32 of a bypass 31 is opened, and refrigerant in a tank 4 is circulated from a pump 6 to the bypass 31 and the condenser 2. After the pump 6 is started, when the temperature 'I: of the condenser 2 is lowered to a set temperature T1 (<T2) or lower, the pump 6 is steadily operated at number of revolutions N2 (>N1), the two-way valve of the bypass is closed, and the refrigerant in the tank is circulated from the pump 6 to an evaporator 11 and the condenser 2.
