Energy-Saving Heat Pump Device

Abstract

An energy-saving heat pump device includes first, second, third, and fourth pipes connected in sequence in a loop. A condenser is mounted between the first and second pipes. An expansion valve is mounted between the second and third pipes. An evaporator is mounted between the third and fourth pipes. A compressor is mounted between the first and fourth pipes. The compressor compresses and outputs a coolant mixture including at least two coolants. The coolant mixture in the first pipe has a pressure of 24-30 kg/cm 2 G and a temperature of 80-125° C. The coolant mixture produces heat while the coolant mixture passes through the condenser. A temperature of water outputted from the condenser is in a range of 45-98° C. The coolant mixture produces cold energy for a cooling medium of the evaporator while the coolant mixture passes through the second pipe, the expansion valve, the third pipe, and the evaporator.

1 . An energy-saving heat pump device comprising:
 first, second, third, and fourth pipes connected in sequence in a loop, with a coolant mixture circularly flowing through the first, second, third, and fourth pipes, with the coolant mixture including at least two coolants;   a condenser mounted between the first and second pipes;   an expansion valve mounted between the second and third pipes;   an evaporator mounted between the third and fourth pipes; and   a compressor mounted between the first and fourth pipes,   with the compressor compressing and outputting the coolant mixture, with the coolant mixture flowing through the first pipe, the condenser, the second pipe, the expansion valve, the third pipe, the evaporator, and the fourth pipe and returning to the compressor, with the coolant mixture in the first pipe having a pressure of 24-30 kg/cm 2 G and a temperature of 80-125° C., with the coolant mixture producing heat while the coolant mixture passes through the condenser, with a temperature of water outputted from the condenser after heat exchange being in a range of 45-98° C., with the coolant mixture producing cold energy for a cooling medium of the evaporator while the coolant mixture passes through the second pipe, the expansion valve, the third pipe, and the evaporator.
