Say no to vapor compression!


“Pumping liquid refrigerant to the cooling coils is up to 40 times more efficient than using the compressor to do the same amount of work” Running compressors when outdoor conditions prevail is approximately 95% waste of electrical resources. Instead, the entire refrigeration load is sustained by running a LPA liquid refrigerant pump, rather than using the system’s compressor. We invite engineers and OEM’s to explore our technologies that makes refrigeration more efficient and more economical.

The U.S. Energy Department today announced nearly $8 million to advance research and development of next-generation heating, ventilating, and air conditioning (HVAC) technologies, supporting the Administration’s goal of saving money by saving energy, and phasing down the use of chemicals that have a devastating effect on the global climate.

With air conditioning using large and growing amounts of energy in the U.S. and worldwide, these innovative solutions offer significant energy and cost savings in new and existing buildings.

Currently, HVAC systems are the largest energy end-use in buildings, using almost 14 quadrillion British thermal units (quads) of primary energy annually, or nearly 30% of all energy used in U.S. commercial and residential buildings. Non-vapor-compression HVAC systems have the potential to use as much as 40% less energy than current systems.

Non-vapor-compression HVAC systems, as the name implies, refers to air conditioning systems that provide heating or cooling but without the compressor component, such as magnet cooling technologies based on the magnetocaloric effect or liquid refrigerant pump heat transfer methods qualify as non-vapor-compression refrigeration technologies.
