Energy-saving air conditioning device capable of accurately controlling air supply temperature and humidity

Abstract

The invention discloses an energy-saving air conditioning device capable of accurately controlling the air supply temperature and humidity. The energy-saving air conditioning device comprises an inverter compressor, a first heat exchanger, a second heat exchanger, a water-cooling condenser, an electronic expansion valve and an evaporator which are sequentially connected through pipelines to form a circulation loop. The first heat exchanger is connected with an outlet of the inverter compressor; and the evaporator is connected with an inlet of the inverter compressor. The evaporator and the first heat exchanger are sequentially arranged in an air supply channel in the direction from an air inlet to an air supply outlet, and a reheating fan with the adjustable air speed is arranged between the first heat exchanger and the air supply outlet and used for adjusting and controlling the air volume passing through the first heat exchanger. The inverter compressor, the second heat exchanger and the water-cooling condenser are sequentially arranged in an exhaust channel in the direction from a return air inlet to an exhaust outlet, and an electric two-way valve is arranged on a circulating cooling pipeline of the water-cooling condenser. The temperature and humidity of the supplied air can be accurately controlled, the energy consumption of the system by the outside is effectively reduced, the working efficiency of a refrigerating system is improved, the condensation heat is fully utilized, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning and energy utilization, in particular to an energy-saving air conditioner that precisely controls the temperature and humidity of air supply. Background technique [0002] In the existing technology, the condensation heat of the air conditioning unit can reach 1.15 to 1.3 times of the cooling capacity. A large amount of condensation heat is condensed by outdoor high-temperature air, and the condensation effect is not good, or the external cold source can handle the condensation heat. , It needs to consume extra energy, and at the same time, this part of heat will be lost in vain, resulting in a large waste of energy. If the condensation heat released by the air conditioning unit is recycled, and the indoor exhaust air temperature is low in summer, it is used as the main cold and heat source of the unit, which can effectively reduce the energy consumption of the condensation heat. For the...

Problems solved by technology

Traditional fresh air dehumidifiers use condensation heat mainly to reheat the fresh air after cooling and dehumidification. Although it solves the problem of relying on electric heating to generate huge energy consumption, the use of condensation and reheating cannot accurately control the temperature of the supply air, and cannot meet the needs of different users.
