Assessment of leakage and risk reduction of R290 in a split type household air conditioner
International Journal of Refrigeration, 2018Abstract R290 (propane) is a famous hydrocarbon substance, but the flammable and explosive characteristics require safety precautions for its use. In fact, R290 is also a refrigerant with low global warming potential (GWP) and excellent thermodynamic properties.

Analyzing for Refrigerant Induced Noise for Split Type Air Conditioner Indoor Unit
Transactions of the Korean Society for Noise and Vibration Engineering, 2006In the air-conditioner, refrigerant induced noise and vibration can be increased when the airflow rate is reduced in order to decrease the noise at the low mode. Through the test and analysis of this kind of noise, it can be verified that the main reasons of refrigerant induced noise are the velocity and flow Induced force of the refrigerant at the ...

Effect of condensing unit layout at building re-entrant on split-type air-conditioner performance
Energy and Buildings, 2002Abstract The use of split-type air-conditioners is popular in residential buildings of Hong Kong. In new apartment buildings, the building re-entrants are the most frequent choice of the project team for placing the outdoor condensing units. Nevertheless, the effect of heat dissipation from all condensing units at a re-entrant can be detrimental ...

As a high-profile replacement for R22 split type household air conditioner (STHAC), R290 has several advantages in terms of thermodynamic properties, environmental characteristics, and cost. However, the obvious shortcoming of R290 is its flammability, which has a potential fire risk to the building. At present, the most important measure to ensure the

Indoor leakage test for safety of R-290 split type room air conditioner
International Journal of Refrigeration, 2014Abstract The selection of alternative refrigerants for the room air conditioner (RAC) industry has, in recent years, been a significant challenge. According to the literature, flammable refrigerants may be one of the potential options. In particular, R-290 (propane) has a major possibility to be the chosen working fluid for the next generation of ...
