Split wall systems

Tecair supply install and maintain split wall systems from suppliers such as Daikin, Mitsubishi, Fujitsu, Hitachi, Gree and many others. Sizing from 2kW for a hotel room through to larger 10kW units. 

Most people are familiar with the sight of air conditioning split wall systems as they are very common in both residential and commercial projects. While Tecair mainly does commercial projects, the equipment is essentially the same.

There is a wall mounted internal fan unit plus an additional exterior unit located outside. In between the two units is piping to and from each, where the gas refrigerant is pumped for heat transfer. Externally the coil is cooled by a fan which effectively transfers the internal heat to atmosphere. Internally, another coil, which has the cooler gas in liquid state, also has a fan to transfer heat from the internal atmosphere in exchange for cooling air going across the coil. The refrigerant gas which is heated internally as part of this process is then pumped back out to the exterior unit where the heat can be transferred to atmosphere. This is the cycle of all compressor driven air conditioning and most commonly found in the split systems described.

Like any other mechanical equipment, split systems need to be properly maintained. The main service points are the filters located in the internal wall mounted unit. These filters need to be changed regular and typically require hosing externally or straight replacement. It is not our usual practice to vacuum the filters as it is better to do the cleaning using water.

Furthermore it is extremely important to clean the coils that are located internally as these can become clogged with microbial growth and dust. It is a moist environment and bacteria and mould will grow. So for healthy, clean air supply we highly recommend coils are cleaned once per year by our specialist technicians.

A protective blue coating can be applied which will warrant the coil for bacterial growth for the next 12 months. This is highly recommended in environments related to help such is doctors practices, dental practices, nursing homes and any other environment where people with weakened immune systems can benefit from healthy air.

Not least of which we highly recommend coil and filter changes for your air conditioning in your home or apartment which we can also assist with.
