Evaluation of N-Butane as a Potential Refrigerant for Household Compressors

In recent years the household compressor manufacturers have reduced the energy losses inside the compressors resulting in a positive effect on the energy consumption in the cabinets. In the following, N-butane, which is a natural and non ozone depletion refrigerant, is compared to refrigerants presently used in household compressors.

An Investigation of Compressor Slugging Problems

Mathematical models have been popularly applied to study the compression processes of superheated refrigerant vapor in compressors. As to the case when refrigerant enters a compressor cylinder in the state of liquid and vapor mixture, however, the availability of fundamental studies is very limited. -A mathematical model is presented to simulate the compression processes of two-phase saturated ...

Estimation, of the Starting Torque, of Refrigerant Rotary Compressors

Estimation of starting torque is very important for motor design and for improvement in compressor efficiency. Especially, when compressors are restarted after a period of inoperation, motors sometimes meet large starting torque. The assumed reasons are as follow . The compressors temperature is sometimes lower than any other parts of the refrigerant cycle. In this case, the refrigerant tends t...

Reducing Compressor Noise While Considering System Interactions

Refrigerant compressors can be a primary noise source in residential air conditioning and heat pump systems. When evaluating the contribution of a compressor to the total noise, it is necessary to consider how the compressor couples to the condensing unit. Compressors typically couple to the condensing unit via three different types of noise paths. First, the compressor couples structurally to ...
