Benchmark Performance Analysis of an Ecm-modulated Air-to-air Heat Pump with a Reciprocating Compressor
نویسنده
چکیده
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 heat pump design tool was used to optimize this ECM benchmark heat pump using speed ranges and total heat exchanger sizes per-unitcapacity equivalent to that used by the highest SEER-rated variable-speed unit presently on the mar& (SEER = 16.4). 19%, while the SEER gain remained at 29%. An SEER of 20 appears to be the limit ofpresent modulated reciprocating technology with conventional sizing and default cycling loss factors.

Vibration Analysis of an Air Compressor Based on a Hypocycloidal Mechanism: an Experimental Study
In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...
