Tyhjiölämpöpumput

Tyhjiölämpöpumput, often referred to as vacuum heat pumps, represent a specific type of heat pump technology that operates under reduced pressure conditions. Unlike conventional air source or ground source heat pumps that utilize ambient pressure, tyhjiölämpöpumput create a partial vacuum within their system. This vacuum lowers the boiling point of the refrigerant, allowing it to absorb heat more effectively even from sources at lower temperatures.

The fundamental principle of operation remains similar to other heat pumps: a refrigerant circulates through a cycle, absorbing heat from a source, transferring it to a higher temperature sink, and releasing it. In a tyhjiölämpöpumppu, the reduced pressure within the evaporator enhances the heat transfer process from the source medium, which can be air, water, or even low-grade waste heat. This increased efficiency at lower source temperatures is a key advantage.

Tyhjiölämpöpumput find applications in various sectors, including industrial processes requiring efficient heat recovery and drying. They can be particularly beneficial in situations where the heat source has a limited temperature or is of low quality. The technology aims to improve energy efficiency and reduce the reliance on fossil fuels for heating and cooling purposes. However, the complexity and cost associated with maintaining a vacuum can be factors influencing their widespread adoption compared to more conventional heat pump systems.
