Title:
HIGHLY EFFICIENT WASTE COLD/WARM HEAT RECYCLING HEAT EXCHANGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/022545
Kind Code:
A1
Abstract:
In a waste cold/warm heat recycling heat exchange device of the present invention, a refrigerant circulates in a closed loop between an evaporator (10) and a condenser (20), a digital sensor (45) for detecting the internal refrigerant pressure and temperature and inputting the detected values to a controller (50) is installed in the condenser (20), a liquid transfer pump (46) and a solenoid valve (47) are installed on the liquid refrigerant pipe (40) to push a liquid refrigerant toward the evaporator (10), wherein the controller (50) having received the detected values from the digital sensor (45) controls the operation of the liquid transfer pump (46) and the solenoid valve (47) according to the detected values, thereby adjusting the flow rate of the liquid refrigerant that flows through the refrigerant pipe (40). Accordingly, since the circulation amount of refrigerant can be automatically adjusted according to the degree of thermal equilibrium and pressure equilibrium generated by the evaporator (10) and the condenser (20), not only stable circulation of refrigerant but also an operation for achieving high-efficiency optimization of waste cold/warm heat recovery are enabled.
