Добавлен 14 июл 2020
Air Change has provided Dedicated Outdoor Air Systems (DOAS) and dehumidification solutions to local Australian and international clients for the past 20 years. Our comprehensive range of products use the latest in HVAC technology to help building designers and engineers enhance indoor climate control, air quality and energy efficiency.
Air-to-air heat or energy recovery technology that minimises the energy penalty of fresh air ventilation was at the core of Air Change's inception. Since then Air Change has progressed its engineering capabilities to include sophisticated refrigeration and control systems, allowing for an innovative product range that solves real-life HVAC problems encountered in modern building design. Our innovation has been acknowledged through the receipt of multiple Australian air conditioning industry awards.

The Digital Scroll Compressor - Improved Capacity Control But Is There a Downside?
The digital scroll compressor is a form of scroll compressor commonly used in commercial air conditioners. It uses an unloading mechanism to provide a form of capacity control.
In this video we will cover the digital scroll compressor and its pros and cons. In the next video of this series, we will cover the inverter scroll compressor for comparison.
The aim of these videos is to help HVAC engineers make more informed decisions when choosing air conditioning equipment.

The Scroll Compressor - Basics & The Fixed Speed Type
Просмотров 32 тыс.3 года назад
Scroll compressors are the most common type of compressor used in commercial air conditioners. But there are sub types of the scroll compressor which can make things a bit confusing. In this video we will cover the basic operating principle of the scroll compressor and the pros and cons of the fixed speed type. In the next two videos we will discuss the digital scroll compressor and the inverte...
Return Air Bypass Mode For ERV & HRV Units - Demand Controlled Ventilation
Просмотров 4,7 тыс.3 года назад
Return Air Bypass is another ERV or HRV unit mode that involves a form of heat exchanger bypass. Its function is quite different to economy cycle mode though, so it is important to understand the difference. In this video we explain Return Air Bypass Mode and how it can further miminise energy consumption by matching ventilation rates with demand.
Economy Cycle Mode for ERV & HRV Units
Просмотров 3 тыс.3 года назад
At Air Change we often get asked how economy cycle mode works with Energy Recovery Ventilators or Heat Recovery Ventilators units. So in this video we will explain it! In our previous video, we covered how ERV & HRV units minimise an outside air load by transferring heat, or energy, between air being exhausted outside and fresh air being supplied inside. Despite saving large amounts of energy s...
