How many square feet is covered by a 2 1/2 ton trane air?Which heat pump size should you buy?
Proper and accurate heat pump sizing requires good knowledge about the system and the right tools.In order to answer the question, "how big of a heat pump do I need" or "what size heat pumps do i need?"There are some useful tips and suggestions from the experts.
More variables should be taken into account if you want to size the heat pump as the climate in North America varies from one extreme to the next.
You can either get a free quote from a professional or check out the sizing guides on the internet.Most of the so-called experts do calculations based on the home floor space or the old heating, ventilating, and air conditioning system.
The proper heat pump size should provide an acceptable indoor comfort: temperature and humidity; energy efficiency and savings.
The air-to-air heat pump is capable of providing both heating and cooling, so it's not uncommon in central and northern parts of North America to find one that is too small to provide most of the heat required by a house.Lower performance and lack of dehumidification will be caused by the heat pump being too large for cooling.
The unit can be exposed to frequent failures and shorter lifespan in humid climates if the unit is not sized properly.The sales reps or contractors are trying to avoid the hassle after the installation when the unit is oversized.
An oversized system costs more, the efficiency is reduced, energy cost is higher, and the comfort is not as expected.Poor humidity control and temperature fluctuations can be caused by the heat pump shutting off often.When the duct leakage is higher, the system works harder to distribute the air.
An undersized unit will work at its maximum capacity for as long as it is needed, in order to meet the set temperature, or even non-stop if it cannot keep up with the thermostat demand, leading to discomfort and potential failure of the compressor.
The goal is to reach the temperature quickly enough for greater comfort and less stress, and easily maintain the set temperature, so your heat pump uses less energy, keeps the efficiency high while maintaining the comfort you expect.
The first thing to do when selecting an air-source heat pump is to determine the correct cooling and heating capacity, which can be found in the unit's specifications.
The Manual J and Manual S procedure is recommended by the Air Conditioning Contractor's Association of America.CSA-F280-M90 is used in Canada to determine the heating and cooling loads.
Manual J is used to determine the heating and cooling loads based on the house structure, size, number of doors and windows, insulation, duct leakage, winter and summer conditions and other factors.The Manual J uses computer programs to simplify calculations.Manual J recommends a temperature of 75 F for the indoor temperature in the cooling mode, but it depends on the user preference.
The manual S procedure is used to pick the right equipment, such as the duct work for the proper air flow, air handler, electric resistance heat, thermostats...Variable speed is better than a single speed because it dehumidifies better and uses less energy.
It's not as simple to fit a heat pump as we think.Bigger is not always better.It is better to meet the heating loads between 80% and 90% and provide not more than 125% of the cooling load, according to the advice of professionals.The estimation will give satisfactory results such as improved performance and comfort, reduced energy use, costs and maintenance.
The table below is a reference for estimating the residential heat pump of the average home in regions with a mild climate.The heating and cooling capacity of the heat pump is expressed in tons.
When the balance point is below 30 F, supplemental heating might be needed.For the mild climates, use the 5 kW heating elements for the heat pump of 1.5-2 tons or 10 Kw for up to 5.0 tons heat pumps.
It's not easy to size a heat pump.It needs to be sized correctly in order to get all the benefits it has to offer.The safety factors that guarantee the comfort for a long time are included in the sizing methods from above.
If you want to know what to expect, how to operate and maintain, service and what are the warranty terms, you should hire an experienced heating, ventilating, and air conditioning contractor.Check out the customer reviews and collect several quotes before that.
The heating/cooling requirements should be based on the heat loss / gain calculations with the ductwork, electrical, plumbing and heating system checked and not on some rule-of-thumb techniques.You don't need to spend a lot of money.
