Applications

Air Handling Unit

AHUs are commonly found in larger commercial and industrial buildings, often on rooftops or in basements Through AHU standard applications and programmable software development platforms, CORESTAR can provide solutions for any complex system.

Cold Rooms

The cold chain includes cold storage facilities such as cold rooms. These facilities are used to store or process chilled and frozen products. They can be located within the actual processing facility or somewhere in the distribution chain.

Energy Storage Air Conditioning

Normally, the temperature operating range of the battery cell is between 20 ℃ and 32 ℃. To ensure the reliable operation of energy storage batteries, there are generally two methods: air cooling and liquid cooling. The air-cooling method uses forced convection of air to cool the air around the battery.

High-temperature Heat Pump Drying

The high-temperature heat pump drying unit is widely used, suitable for drying bedding in hotels, seafood, fruits and vegetables, grains, wood, tobacco, chemical products, sludge, etc. Its excellent energy-saving effect has been proven by various experimental research institutions all over the world.

Residential

The residential application is a system that combines building temperature regulation and air conditioning systems to control indoor temperature, humidity, and air cleanliness, ensuring a constant temperature, humidity, oxygen, cleanliness, and static effect for 24 hours.
