Canadian researchers are now trying to exploit much more energy from solar sources, hydropower, wind, and biomass. Given the fact that reducing the carbon pollutant level is a political priority in Canada, this paper studies the feasibility of providing sanitary hot water and space heating demands of a four-member family in 10 provinces in this country. The feasibility analysis was performed by...

Frost protection or protecting plants from cold temperatures where they could be damaged must be a consideration in vineyard planning. Cold protection events commonly occur during “radiation” frost conditions when the sky is clear, there is little wind and strong temperature inversions can develop. These conditions can happen during spring, fall or winter when it is necessary to keep canes, bud...

This paper presents the development of a transcritical CO2 heat pump water heating system model incorporating analytical heat exchanger models and an empirical compressor model. This study investigated the effects of a suction line heat exchanger (SLHX) and once-through versus multi-pass water heating schemes. The once-through systems outperformed the multi-pass systems by 10% for the system wi...
