High-efficiency dehumidification air conditioning indoor unit

Abstract

The invention discloses a high-efficiency dehumidification air conditioning indoor unit which comprises a machine body. A fan, a motor, a snake-shaped coil pipe and a condensation water disc are arranged in the machine body. The fan is electrically connected with the motor. The snake-shaped coil pipe is placed on the condensation water disc. A heat exchanging coil pipe is arranged in the middle of the snake-shaped coil pipe. A pre-cooling section which cools air and a reheating section which heats air are arranged on the two sides of the snake-shaped coil pipe respectively. The reheating section is connected with an air outlet for air going out. According to the high-efficiency dehumidification air conditioning indoor unit, through structure arrangement of the coil pipe, energy is reallocated, under the situation that no extra energy loss is increased, the effects of pre-cooling, undercooling dehumidification and reheating on damp hot air are achieved, so that heat exchanging efficiency is improved, and the purpose that dehumidification amount is increased, indoor air quality is improved, and energy loss is lowered is achieved.

Description

technical field [0001] The invention relates to machinery and equipment, in particular to a high-efficiency dehumidification air-conditioning indoor unit. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the air quality of the indoor living environment are also getting higher and higher. As we all know, the comfort of the environment is not only determined by the temperature, but also related to factors such as the relative humidity of the air. [0003] Due to the small enthalpy difference and low dehumidification capacity of ordinary air-conditioning indoor units, in hot and humid areas with high latent heat load, places with high traffic density such as shopping malls and underground spaces, even if the air-conditioning indoor units are selected according to the total heat and cold capacity, It cannot fully meet the dehumidification requirements. On the contrary, the room temperature is too low or the ai...

Problems solved by technology

[0003] Due to the small enthalpy difference and low dehumidification capacity of ordinary air-conditioning indoor units, in hot and humid areas with high latent heat load, places with high traffic density such as shopping malls and underground spaces, even if the air-conditioning indoor units are selected according to the total heat and cold capacity, It cannot fully meet the dehumidification requirements. On the contrary, it will cause the room temperature to be too low or the air conditioner to shut down frequently due to excessive sensible heat and cold capacity.

Although the content of water vapor in the air is reduced, because the latent heat of vaporization of water is relatively high, it is a high-energy-consuming task to dehumidify with this ordinary air-conditioning indoor unit.
