Reverse Cycle Refrigerated Systems Using Solar

Can a reverse cycle refrigerated heating and cooling system be run on solar alone?

Living in Melbourne – You need reliable heating and cooling all year round.
This means ensuring you have the most cost-effective solutions to heat and cool your home all year round.
In July, the Victorian Government announced that the state will start to move away from relying on gas in homes and new houses will no longer have mandatory gas connections. You can read the announcement here.

Electric Heating and Cooling Options

During the cold season you need to find heating options that are not going to be expensive.
Regular electric heating consumes too much energy, leading to sky high electricity bills.

As electricity prices continue to rise in Australia, more and more people are turning to solar power to reduce their electricity consumption. Solar is an excellent source of renewable energy and helps you save money at the same time.

In recent years, electricity prices for manufacturing businesses and households have risen. These costs are expected to continue to grow in the coming years. With the cost of electricity expected to increase by a further 9% per year over the next four years, people are looking to solar energy as an alternative solution.

The Australian Energy Council estimates that 3.04 million Australian homes and businesses will have rooftop solar by 2022 and the number of Victorian homes installing solar is increasing every year.

How reliable is a solar system for refrigerated reverse cycle heating in winter?

You may think that Melbourne with colder weather will mean that solar panels are inefficient in the winter months. This is not true at all. Solar panels will produce power from sunlight even if the temperature levels fall below zero.
As long as there is sunlight or UV rays – Solar energy can be produced. because they absorb energy from abundant sunlight rather than heat. Cold climates are optimal for the efficiency of solar panels as long as sunlight is shining on them.

Even on rainy or cloudy days and even when it snows, solar energy is still able to be produced as the panels can use diffused or indirect sunlight (radiation) to generate energy.
In winter there will be less sunlight and less time during the day that the panels will operate at full capacity – Victorian homes can run their heating and cooling for the most part entirely with their solar system.

As the winter season can shorten the operating time of a solar system at total capacity, an additional solar battery storage system that can store excess energy from your panels can go a long way towards ensuring your home’s energy security. and if they add storage batteries, this will cover them for night time use.

Refrigerated Reverse Cycle Heating Is The Most Energy Efficient When Correctly Installed

Majority of home owners are looking for heating that is not only cost-effective but it also must be effective at heating a home and maintaining a comfortable temperature during the day and night.
Reverse-cycle heating and cooling systems installed into a suitable home will tick all the boxes when it comes to climate control and power costs. When you combine using solar power you will save even more with the energy or power usage.

Reverse-cycle refrigerant air conditioning systems that can also be used as highly efficient heating units during the cold season.
By installing a ducted system, every room in the home and can be effectively climate controlled for the occupants in each room or area and take into consideration on the power usage needed in each area.
This is called zoning, each zone is looked at for the size of the area and environmental factors such as window positions, the sun aspect, door ways and how well insulated the room is.

Before Installing Your Ducted Heating And Cooling System

Beyond Heating And Cooling have been installing ducted refrigerated systems in Melbourne for the past 10 years. They are mechanical plumbers and are licensed to install all ducted systems including gas, evaporative coolers and refrigerated reverse cycle systems.
They can also install split system air conditioners as well.

To work with the team at Beyond Heating and Cooling , it is really easy and FREE.
We will ask you to send through your house plans/ diagrams. If you do not have them – Don’t worry as we can also create our own plans.
We will then book a time to come to your home or workplace so we can run through your requirements and take into consideration each room’s size, the suns orientation, the insulation with walls and ceiling, window sizes and what window coverings you have.

Designing your heating and cooling system must take all of these into consideration and to ensure that the system is effective we will suggest in some changes need to be done – Such as getting block out curtains or putting in draft stoppers under doors or trimming the garden around where the outdoor unit is to be placed.
We will also decide where the inside motor needs to go – If it is to be in the roof cavity or if your home is on stumps, this can also be considered.

The Parts Of A Ducted System

  1. Evaporator: When in cooling mode warm air is extracted through the return air grille. The air passes over coils which are filled with cold refrigerant liquid. The warm air passing over the coils is cooled down and it circulated back into your home via the ducts and vents. As the the refrigerant gets warm it turns into a high pressure gas.
  2. Compressor: The warmed refrigerant gas flows through to the compressor which is an outdoor unit. The compressor re pressurises the refrigerant gas, which condenses it back into a liquid.
  3. Condenser: This is part of the outdoor unit and the refrigerant liquid flows through coils in the condenser. A fan blows over the coils, which removes heat from the liquid refrigerant.
    The liquid keeps traveling and is depressurised further which keeps cooling the now liquid refrigerant. It is then returned to the evaporator to keep the cycle repeating
  4. The return air grille: Where air is pulled from your home.
  5. Filter: Is in the return air grille, and helps to filter dust, dirt, and other pollutants.
  6. Thermostat: Measures the temperature of each zone and is self adjusting to keep each zone at the required temperature.
  7. Controllers: Usually are wall mounted. New ducted systems come with smart features, so you can control the system from other devices such as your phone, tablet, or laptop.
