Invention of the Vuilleumier (VM) cycle from which the thermodynamic principles of TCHP™ would evolve.
From the early 1960s to the late 1970s, researchers at labs including the Technical University of Munich, Phillips Research, the U.S. Air Force, and NASA, built small VHPs for low-temperature cryogenic cooling applications.
The most comprehensive research program was completed by a collaboration between the Technical University of Dortmund and Bosch-Viessmann Energie (BVE) in the 1990s.
The company was founded by Paul Schwartz, and Prof. Dr.-Ing. Peter Hofbauer in 2012 when informal discussions led to the realization that there was a tremendous unmet need in the HVAC industry.
Work begins on Gen 1 – TCHP™ prototype, which would demonstrate the fundamental thermodynamics and unique thermal compression concepts of the system.
▪ DOE and NYSERDA funding $1.3 million
▪ Series A investor funding $1.7 million
Work begins on Gen 2 – TCHP™ prototype, with thermodynamic concepts validated, the 2nd generation prototype focused on component optimization, improved system design, and utilization of low-cost production.
Wells Fargo funding grant $250,000
ORNL and NREL visit ThermoLift for inhouse testing of the Gen 2 TCHP prototype
Series A-1 investor funding $5.9 million
Work begins on Gen 3 TCHP™ prototype, this generation focused on system, burner and mechatronic strategies to improve power and load response.
Series B investor funding $8.2 million
Demonstration test at ORNL achieved heating COP of 1.5 at 8˚C and natural gas driven cooling to -100°C (approximately -150°F).
