Holtop air - conditioning unit with large - space nozzle - type jet indoor unit can realize long - distance air supply in large space without air ducts while meeting the requirements of cooling and heating. It has the characteristics of saving installation space, reducing investment costs and low operating costs. At the same time, the air supply angle of the unit can be adjusted freely to ensure that cold and hot air is delivered to the designated position. The unit frame is integrally rolled and formed with color steel plates, and a unique cold - bridge breaking structure is formed inside with PVC heat insulation sleeves. While improving the strength, it isolates moist and cold air to avoid condensation on the surface of the unit.
The unit panel adopts an embedded assembly structure, and a new type of polymer sealing material is used for sealing between the panel and the frame. It is convenient for disassembly and maintenance and ensures an extremely low air leakage rate, thus ensuring good air tightness of the unit.
The unit panel adopts a standard "sandwich" panel structure. The outer panel is a color steel plate, the inner panel is a galvanized steel plate, and polyurethane foam thermal insulation material is sandwiched inside, so the thermal insulation performance is excellent.
According to the requirements of air volume and static pressure value, high - quality brand fans are selected. The fan impellers and belts are corrected for static and dynamic balance and vibration. The base is equipped with shock absorbers, and the air outlet is designed according to aerodynamic performance, with a soft connection with the box body, which effectively reduces vibration transmission and operates stably and reliably.
