Abstract

The invention relates to an energy tower absorption type hot and cold water unit and belongs to the field of heating air conditioners. The unit comprises an absorption type cooling heat pump unit, an energy tower and a secondary refrigerant regenerating device which are combined. In winter, the absorption type cooling heat pump unit is driven to operate through heat energy or fuel so as to provide the heating function, low-quality heat energy is extracted through heat and mass transfer of the energy tower and the air, and accordingly primary energy efficiency of heating is increased evidently. In summer, the unit is switched into a absorption type cooling mode, heat is discharged to the energy tower, and power grid load can be reduced effectively by heat energy or fuel cooling. The energy tower absorption type hot and cold water unit has the advantages that the energy tower is small in investment and does not frost by taking heat in the air in winter, and reliability and continuity of heating are guaranteed; continuous regeneration of secondary refrigerant is achieved through self smoke discharge or heat pump refrigerating, use amount of secondary refrigerant is reduced, and energy consumption for secondary refrigerant regeneration is lowered greatly; the energy tower absorption type hot and cold water unit used for heating in winter and cooling in summer has evident effects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to an energy tower-type absorption cold and hot water unit. In winter, the energy tower takes heat from low-temperature and high-humidity air to improve the primary energy efficiency of the heating system. Or fuel cooling can effectively reduce the grid load. The investment of the energy tower is small, and the heating from the air in winter will not cause frost, which ensures the reliability and continuity of the heating supply, and can realize the continuous regeneration of the solution through various energy-saving means. This technology is especially suitable for heating in winter and cooling in summer and in areas with sufficient fuel supply, and belongs to the field of heating and air conditioning. Background technique [0002] Heating and air-conditioning consume a lot of energy. In recent years, due to the large-scale use of electric cooling and air-conditioning in cities, the pressure on the power grid has increased shar...
