Lämpöpumpputekniikat

Lämpöpumpputekniikat, or heat pump technologies, refer to systems that transfer thermal energy from a colder source to a warmer sink using a mechanical compression and expansion cycle. This process is the reverse of a refrigeration cycle, allowing for efficient heating of buildings and water. The fundamental principle involves a refrigerant that evaporates at low pressure and temperature, absorbing heat from the environment, then is compressed, increasing its temperature. This high-temperature refrigerant then condenses, releasing heat into the heating system, and finally expands through a valve, reducing its pressure and temperature to repeat the cycle.

There are several common types of heat pump technologies. Air-source heat pumps extract heat from the outside air, making them a popular and relatively easy-to-install option. Geothermal heat pumps utilize the stable temperature of the earth or groundwater as their heat source, offering higher efficiency but requiring more complex installation due to ground loops. Water-source heat pumps, similar to geothermal, draw heat from nearby bodies of water. Exhaust air heat pumps recover heat from the stale indoor air being vented out of a building. The efficiency of these systems is measured by their Coefficient of Performance (COP), which indicates the ratio of heat delivered to the energy consumed. Lämpöpumpputekniikat are increasingly recognized for their energy-saving potential and reduced environmental impact compared to traditional heating methods.
