Performance analysis of capacity control devices for heat pump reciprocating compressors

Optimum Utilization of Capacity Control Devices in Reciprocating Compressors

capacity control consists of adjusting the quantity of gas supplied by the compressor to suit the fluctuating demands of the plant. In the modern processing plants, energy costs amount to about 65 per cent of the cwerall costs. Therefore, it is of paramount importance that the control system should be such that the compressor power is almost proportional to the quantity of gas delivered. For th...

Benchmark Performance Analysis of an Ecm-modulated Air-to-air Heat Pump with a Reciprocating Compressor

A benchmark analysis was conducted to predict the maximum steady-state pet$onnance potential of a nearterm moduikting residential-size heat pump. Continuousiy variable-speed, permane nt-magnet electronically commutated motors (ECMs) were assumed to modulate the compressor and the indoor and outdoor fans in conjunction with existing modulating reciprocating compressor technology A modulating hea...
