A method providing for a first industrial process that produces heat, extracting a waste heat from the first industrial process, providing the extracted waste heat from the first industrial process to a second process, conducting at least one cooling process.

The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that prevents the refrigerant from flowing backward to the first regenerator under a low pressure condition by installing a gas-liquid separator that separates the refrigerant discharged from the first and second regenerators and flows into the condenser into a gas state and a liquid state, in order to heat the absorption solution supplied from the absorber to separate into a refrigerant and an absorbent, and to smoothly discharge the refrigerant from the first regenerator and the second regenerator for discharging the separated refrigerant to the condenser.

The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that connects a bypass collection pipe that guides an absorbent flowing back into the second regenerator to be collected into an absorber to a second collection pipe, in order to prevent the water level of the second regenerator from being raised as the absorbent cannot be collected by the absorber and flows back to the second regenerator, due to the pressure difference between an absorbent separated from the first regenerator and collected into the absorber through the first collection pipe, and an absorbent separated from the second regenerator and collected into the absorber through the second collection pipe.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

A method operates an absorption heat pump system, specifically the flow of hydronic cooling fluid through the condenser during system start-ups, or when the cooling fluid temperature is low. To minimize the time for an absorption heat pump to reach full cooling or heating capacity, it is desirable for the high side pressure to increase as fast as possible, and the low side pressure to decrease as fast as possible. Since the high side pressure is a function of the temperature of the refrigerant exiting the condenser, if the condenser cooling fluid temperature is low, the corresponding high side pressure will be low, which may not permit adequate working fluid flow rates from the high pressure side of the system to the low pressure side.
