The air-cooled modular unit is an integrated central air conditioning device based on modular technology, using air as the cold (heat) medium and serving as both a cold (heat) source. The air-cooled modular units available on the market are divided into single cooling type and heat pump type. On the market, air-cooled modular units generally refer to air-cooled modular units of the heat pump type, also known as air-cooled heat pump units.
The unit features high efficiency, low noise, reasonable structure, simple operation, safe running, and convenient installation and maintenance. It is widely used in public places such as hotels, shopping malls, office buildings, exhibition halls, airports, and stadiums, and can meet the different usage requirements of air conditioning systems in industries such as electronics, pharmaceuticals, biology, light textile, chemical engineering, metallurgy, power, and machinery.
Air cooling modular units are divided into single-cooling type and heat pump type. Among them, the heat pump type air-cooled modular unit integrates refrigeration and heating functions, capable of both cooling and heating. It can achieve cooling in summer and heating in winter, serving multiple purposes with one machine. Therefore, air-cooled heat pump units are usually the preferred solution in HVAC engineering designs where there are no heating boilers, no heating networks or other stable and reliable heat sources, but air conditioning is required throughout the year. This unit can be combined with fan coil units or cabinet-type, ceiling-mounted air handling units and fresh air units to form a semi-centralized air conditioning system, which has many advantages of fan coil unit systems and is flexible in layout. It features an attractive appearance, saves building space, is easy to adjust, can be stopped and started independently without affecting other rooms, and has low operating noise.
We provide professional air-cooled central air conditioning system customized services, dedicated to creating efficient, energy-saving, and comfortable air conditioning solutions for our clients. Our services include preliminary system design, matching air-cooled main units, air conditioners, and fan coil units, ensuring the integrity and efficient operation of the entire air-cooled system.
The GRAD air source heat pump unit is equipped with a self-developed NB-iot Internet of Things remote intelligent control module. It can be operated via a mobile phone APP, eliminating the need for dedicated personnel to stand by. It offers fault early warning prompts and online diagnosis. It can operate efficiently in an ambient temperature range of -30℃ to 43℃, with a maximum water outlet temperature of 60℃. It has various terminal forms and is suitable for radiator, floor radiant, central air conditioning cooling and heating. The national patented intelligent defrosting technology accurately detects frost, quickly defrosts, significantly reduces the frequency of defrosting, and greatly shortens the defrosting time. In addition, this unit also has unique advantages such as modular customization, no need to build a machine room, environmental protection and energy conservation, high efficiency and low noise, and wide application range.
