ilmalämpöpumppuun

An ilmalämpöpumppu, or air source heat pump, is a type of heating and cooling system that transfers heat from the outside air to the inside of a building during the winter, and from the inside air to the outside during the summer. This process is reversed in heating and cooling modes. The primary components of an ilmalämpöpumppu are an outdoor unit containing a compressor and a coil, and an indoor unit with a fan and another coil. Refrigerant circulates between these units, absorbing heat from the warmer environment and releasing it into the cooler one.

During the heating season, the outdoor unit extracts heat from the ambient air, even when temperatures are below freezing. This heat is then compressed and transferred indoors, warming the building. In the cooling season, the cycle is reversed. The indoor unit absorbs heat from the indoor air and transfers it outside, thus cooling the space. This technology is known for its energy efficiency because it moves heat rather than generating it, which typically requires less electricity than traditional resistance heating.

The efficiency of an ilmalämpöpumppu is measured by its Seasonal Coefficient of Performance (SCOP) for heating and Seasonal Energy Efficiency Ratio (SEER) for cooling. Higher SCOP and SEER values indicate greater efficiency. Modern ilmalämpöpumput are designed to operate effectively in a wide range of climates, although their performance can be reduced in extremely cold temperatures. Regular maintenance, such as cleaning filters and checking refrigerant levels, is important for optimal performance and longevity. They are a popular choice for residential and commercial buildings seeking an energy-efficient solution for climate control.
