Warmth pumps are devices that can consider heat from one particular area and then produce that warmth to one more spot at a higher temperature. Your house refrigerator is related to a warmth pump. toplotne črpalke is that the fridge does not compress the refrigerant gas to elevate the temperature, it just attracts the warmth from the contents of your fridge and dispatches that warmth by means of the heat exchanger (the grill) at the rear of the fridge.Heat pumps extract renewable vitality from the ground, drinking water or air (which have been heated from the sunlight) and transfer it to your property at a ratio of one:4 or a lot more. Let’s say for every one KW/h of electrical power that you use to drive the heat pump, close to four KW/h of warmth will be developed for use in your home.
There are a few distinct varieties of warmth pumps:
Floor resource warmth pumps (GSHP)
Drinking water supply warmth pumps (WSHP)
Air source heat pumps (ASHP)
This post gives details on air supply warmth pumps.
The rewards of air resource warmth pumps are that they are:
Less costly to obtain than other heat pumps this sort of as ground and water resource heat pumps
Simple to set up – can be installed in flats
Far more strength successful than conventional non-renewable vitality methods
Able of having reverse-cycle, ie. has a heating and cooling method like all geothermal heat pumps
Accessible as ‘Reverse Cycle chillers’ capable heat pumps that supply additional heating and domestic sizzling drinking water choices
Energy effective and outcome in reduced yearly gas charges
The down sides of air resource warmth pumps are that:
They are not as productive as other heat pumps, this sort of as floor and water resource heat pumps
The overall performance and efficiency of air resource heat pumps can be affected by:
Sustained temperatures beneath freezing
High or no wind circumstances
Can be noisy though some systems are quieter than other individuals
Can be intrusive though trim-lined versions are accessible
When Deciding on An Air Supply Warmth Pump, contemplate the subsequent details:
Select a warmth pump that has defrost management. Essentially this reverses the warmth circulation to defrost the exterior coil which will minimize the supplementary electrical vitality use for heating by the heat pump.
Don’t forget that supporters and compressors make noise. If at all attainable try out to locate the outside the house unit absent from home windows and from any home windows in adjacent properties. Noise can be more decreased by mounting the external unit on a audio absorbing base. All external units need to have a audio ranking – try selecting models that have a seem score of 76 decibels or reduce.
Make sure that the out of doors device is secured from substantial winds as this will influence the performance of the warmth absorption process. The appropriate fencing and planting can accomplish this. There are in growth ‘Cold Local weather Warmth Pumps’ that have a two speed two-cylinder compressor, and a again-up booster compressor. These characteristics let this program to function proficiently in temperatures as lower as -9oC.
If you are going to use the warmth pump far more in the heating manner fairly than the cooling mode then putting in the indoor device in a minimal wall posistion is much better as this will boost its heating performance. This is simply because heat air rises. However, if you are utilizing the heat pump much more for cooling, then install the unit substantial on the wall as this position will enhance its cooling performance.
There are slender-lined indoor heat pump models available. They can be recessed into the wall to make them much less intrusive in the place.
