Abstract

The invention relates to the technical field of air conditioner units, in particular to an air conditioner unit with horizontal cross flow indirect evaporation refrigeration devices. The air conditioner unit comprises a unit shell, the indirect evaporation refrigeration devices and direct evaporation refrigeration devices; an exhaust fan and an air feeder are arranged in the unit shell, and the indirect evaporation refrigeration devices are arranged at the positions, located on the left side and the right side of the exhaust fan, inside the unit shell; each indirect evaporation refrigeration device is internally provided with an air returning channel, a first fresh air channel and a first spraying circulating water channel; and a first spraying device is arranged at the upper end face of each indirect evaporation refrigeration device. The air conditioner unit is compact in structure, small in appearance size and capable of effectively avoiding leakage hidden troubles during circulating water heat exchange, has the beneficial effects that energy is saved, uniform air outlet is achieved, the indoor noise is low, a water circulating system is simple in flow, running is safe and reliable, and the indoor air quality is high, and can achieve running under the multi-mode multi-station condition.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units, and relates to an air-conditioning unit with a horizontal cross-flow indirect evaporative refrigeration device. Background technique [0002] The air conditioning units used in public buildings have large air handling equipment and complex pipeline transmission and distribution systems, and the corresponding air handling units will occupy a part of the building area. This heat exchange method has hidden dangers of circulating water leakage and is not very safe; most of the air-conditioning systems used in residential buildings and other civil buildings have a part of the air return operation, resulting in insufficient fresh air volume and poor comfort. Refrigerants such as Freon have a relatively large impact on the environment. As people's requirements for the comfort of the living environment are increasing, air-conditioning equipment requires compact air-conditioning units, high...
