Title: Methodology to estimate vapor quality of refrigerant leaks

Abstract

The US Department of Energy (DOE) Building Technology Office (BTO) and the Air-conditioning, Heating & Refrigeration Technology Institute (AHRTI) are sponsoring an experimental study of refrigerant leak characteristics. The objectives are to conduct refrigerant leak tests on several heating, ventilating, air conditioning and refrigeration (HVAC&R) systems under operating conditions representative of actual applications to document the pressure decay rate and the mass flow rate of leaked refrigerant as a function of time. Another aspect of the study was to formulate and document a procedure for estimating the quality (vapor versus liquid) of the leaking refrigerant and oil escaping from the high- and low-pressure sides with the unit energized and with the unit turned off. Refrigerant quality was estimated by tracking total system weight of a packaged air-conditioning (A/C) unit and the total weight of a large container used to capture the refrigerant leakage escaping the packaged unit.
