There is no difference between cooling and heating a person's house, business, or commercial facility. Asking yourself this question will help you choose your goals. Utilizing contemporary, technologically sophisticated reverse cycle air conditioners or highly efficient gas heating equipment can not only keep you warm but also enable you to save money and lessen your carbon footprint.

Reverse cycle air conditioners, gas-fired systems, and premium brand heating units are all available from DGB Refrigeration as ducted solutions for projects of all sizes. The majority of well-known models of reverse cycle heating use inverter technology, which enables the compressor's rotational speed to change depending on the unit's necessary output. As a result, the device never entirely shuts down. This might reduce your energy use by 30 to 50 percent. Additionally, these devices achieve the correct temperature more quickly and keep it constant.

DGB Refrigeration proudly provides services all across Melbourne and its Surrounding suburbs.

We can come to you to talk about your needs and provide the finest choice for your house or place of business. DGB Heating and Cooling have years of expertise, so you can trust us to take care of your work and provide exceptional after-sale service. One of the most often used methods for heating a whole house is ducted heating, whether it is gas or refrigerated. It is also known as gas ducted, central ducted, or reverse cycle ducted. When you use ducted gas heating, the air is drawn from within your house into a return air grille, warmed in the central heating unit, and then dispersed to each room via a network of ducts connected to outlets. As a consequence, your gas heating system will provide warm, soft air.

Split System

A split system is a refrigerant air conditioner that consists of two different units: the interior unit, which has an evaporator, and the exterior unit, which has a compressor and condenser. Hot air from within is expelled by the outdoor condenser and compressor unit, while cold air is blown inside by the inside unit's evaporator. Imagine it as a sophisticated filtering system. The condenser for reverse cycle air conditioners is similarly housed inside the indoor unit. Insulated tubes are then used to link the two devices. These tubes are then routed through a wall hole. Reverse cycle and conventional split system air conditioners are both quite small, quiet, and energy-efficient.

At DGB Refrigeration we do the installation, repair, and service of the brand’s split system.

Ducted Refrigerated Air Conditioning

One of the most effective methods to heat and cool your house is using ducted refrigeration. Ducted systems, as opposed to conventional split-system air conditioners, use a network of ducts to distribute heated or cooled air throughout your whole home. This enables you to keep your living environment at a constant temperature for optimal comfort. Ducted systems are also far more energy-efficient than conventional split systems, making them a great option for anyone trying to lower their energy usage.

Ducted refrigerated air conditioning is unquestionably something to take into consideration if you're looking at Whole Home Air Conditioning. All weather situations can benefit from ducted refrigeration and air conditioning.

Evaporative Cooler

Unlike other systems that employ vapor-compression or absorption, an evaporative cooling system cools by using the principles of evaporation. When warm air enters a space, water droplets on the air particles quickly evaporate, bringing the temperature down. These water droplets are directed into a collecting reservoir that has been created specifically to remove heat. Through the vents to which it is linked, cool air entering the room is spread evenly. The water droplets' ability to evaporate is what enables the temperature of the fresh hot air stream to be lowered. Through vents or ducts, that warm air is distributed throughout the whole structure.

This system offers a natural cooling method that does not require the use of coal, gas, oil, or electricity to function.

Wet filtering pads are used in this system to cool and humidify the dry air while drawing heat out of it. Both the temperature and the relative humidity can be lowered via evaporative cooling devices. Fewer condensation forms in colder air because of decreased relative humidity. Evaporative cooling can be helpful in arid locations when the air's moisture content might be as low as zero. To keep the temperature comfortable in places with greater humidity levels, a dehumidifier could be needed.
