With out carrying out a full building heat loss evaluation, and calculating its related energy consumption profile and the new water necessities of the buildings occupants. You can not accurately design a ground source warmth pump system.
The main drawback with many renewable energy installations is, that compared to normal energy systems equivalent to fuel/oil or electric, the installed costs are usually a lot higher, thus which means the economies of scale are more limited. An oversized Heat pump will spend most of its time running below half load conditions, which can lead to a shortening of the equipments lifespan and in the end have an effect on performance.
Below-sizing may end up in a system that requires another heating system for use, instead of the GSHP in periods of cold weather. This is known as an alternative bivalent system and is not very efficient. A top up system can be required to help the system meet its requirements. Whilst it is the truth is fairly normal to have what is called a parallel bivalent system, the place techniques work together during periods of peak loads, the Heat pump pompe de caldura sol apa pret will work at most output providing the bottom load of the heating, whilst the other system tops up the temperature levels. It is vitally important to know the buildings and its occupant’s energy necessities so that essentially the most energy environment friendly and therefore cost efficient system is designed, as generally the usage of non renewable supplementary heating should not exceed 5% of the annual energy requirement.
It is not only the sizing of the warmth pump that must be considered when designing the system. Different ground circumstances could have an affect on the efficiency of the ground coil or borehole system used to gather warmth from the ground. It is broadly thought that ground supply heat pump techniques take their heat from geothermal warmth nonetheless, this only happens in a number of areas of the UK.
The ground collects solar energy and virtually all of the ground heating effect comes from the sun, even up to hundreds of meters below ground level. The type of ground ie, sand/gravel, rock, clay have different levels of heat extraction. Even the moisture levels of the ground will impact the performance and therefore the design of the system.
With no ground condition survey being carried out one could not even say whether or not a coil system is appropriate. If the ground situations are such that there’s allow us to say, 1m of topsoil over rock then the cost of the set up will vastly increase.
