PURPOSE: A hot water circulation system interlocked with a heat pump and a method for controlling the same are provided to streamline the installation processes of the system and reduce manufacturing costs by forming one coolant heat-exchanger which is heat-exchanged with a heat pump coolant cycle. CONSTITUTION: A hot water circulation system interlocked with a heat pump comprises an outdoor unit(2), an indoor unit(3), a hot water circulation unit(1), and a bypass unit. The outdoor unit comprises a compressor(21), an outdoor heat exchanger(23), and an extension part(24). The outdoor unit enables a heat pump coolant cycle. The indoor unit comprises a coolant heat exchanger(31), a sump tank(34), and a water pump(36). The coolant heat exchanger heat-exchanges the coolant and the water discharged from the compressor. The sump tank stores water passing through the coolant heat exchanger. The water pump pumps the water discharged from the sump tank. |
