Winter and summer dual efficient heat-pump air-conditioner method and system based on energy tower

Abstract

The invention discloses a winter and summer dual efficient heat-pump air-conditioner method and system based on an energy tower. The system comprises a vapor compression cycle loop, a spray water cycle loop, a closed air cycle loop, a solution cycle loop, an anti-freezing solution cycle loop and a cooling water cycle loop. The system can operate in a winter operating mode and a summer operating mode; in winter, the system operates like a typical heat-source-tower heat pump system, anti-freezing solutions in four packed towers absorb heat from air, are heated up and then enter an outdoor unit to release the heat; in summer, the system is a vapor compression refrigeration system and a solution dehumidification evaporation supercooling system based on a cooling tower, the first packed tower, the second packed tower and the third packed tower are used for the solution dehumidification evaporation supercooling system, and the fourth packed tower serves as the conventional cooling tower and operates to supply cooling water to a condenser. Rational utilization of the summer unused packed towers of the heat-source-tower heat pump system is achieved, and a winter and summer dual efficient heat-pump air-conditioner is achieved.

Description

technical field

[0001] The invention relates to an energy tower-based high-efficiency heat pump air-conditioning system in winter and summer, which is a method and device for rational utilization of idle packed towers, and belongs to the technical fields of heat source tower heat pumps, solution dehumidification, and indirect evaporative cooling. Background technique

[0002] Due to the depletion of fossil energy, the energy problem has become an important bottleneck restricting economic development. With the continuous improvement of living standards, people have higher and higher requirements for the comfort of living and working environments, and the demand for building cooling and heating is increasing. The larger the building energy consumption is, the greater the proportion of building energy consumption. Therefore, realizing energy saving of building air-conditioning systems has become an important way to alleviate the energy shortage.
