Water evaporation during windshield defrosting is investigated paying particular attention to the effects of air humidity and wind speed. During the defrosting process, the ice layer on the windshield begins to melt as the temperature of the defrost air increases. Results have shown that the iceturned-water can evaporate depending upon the ambient air humidity level and the wind speed. Water evaporation takes the heat otherwise available for melting, thereby delaying the ice melting process. It is found that at low wind speeds the effect of air humidity in delaying the ice-melting is minimal. However, at high wind speeds, (>10 m/s) water evaporation can take enough heat away from melting, thereby significantly reducing the ice removal rate. In relation to this, driver safety concerns associated with the reduction of ice melting rate are discussed.

A large amount of heat is needed to maintain the thermal comfort of both indoor and outdoor swimming pools in cold seasons. This motivates the development of various heating technologies aiming to reduce energy use, as well as operating and investment costs. Although their development can be traced back to the 1960s, a comprehensive review of these technologies is lacking. Therefore, this paper presents a comprehensive review of the development of heating technologies for swimming pools. This review firstly introduces available heat transfer models that can be used to calculate or predict heat loss and heat gain for swimming pools. Then, different passive and active technologies are summarized. The active heating technologies used for indoor swimming pools include solar collector, heat pump, waste heat recovery, geothermal energy, and congregation technologies. The active heating technologies used for outdoor swimming pools include solar collector, heat pump, PCM storage, geothermal energy, biomass heater, and waste heat recovery technologies. A discussion is presented on the practical and possible heating techniques for swimming pool applications. Finally, through the reviewed literature, future research opportunities are identified, to guide researchers to investigate swimming pool heating systems with suitable and relevant technologies.

Improving Ventilation Efficiency for a Highly Energy Efficient Indoor Swimming Pool Using CFD Simulations

The operation of a typical indoor swimming pool is very energy intensive. Previous studies have shown that high quality thermal building envelopes, i.e., with high levels of insulation and airtightness, make it possible to rethink conventional ventilation concepts. Due to the reduced condensation risk in and on envelopes of high thermal quality, ventilation design can be optimized for indoor air quality rather than for averting condensation on the facade. This work investigates different air distribution concepts for an existing swimming pool via computational fluid dynamics (CFD) simulations to evaluate their ventilation efficiency. To reduce modelling and computational resources, the velocity and turbulence fields produced by the swirl-diffusers are determined in a set of separate CFD simulations and incorporated into the swimming pool models. The results show that the ventilation efficiency in the examined swimming pool could potentially be improved with various alternative air distribution concepts, therefore improving the indoor air quality. Although the results seem plausible and compare well with the limited measurement data of air humidity, a more formal experimental validation is still needed before generalizing recommendations.
