runs below the dew-point temperature of the incoming air in order to maximize sensible cooling capacity as_x000D_
well as to provide dehumidification. The condensate that forms on the fins of the cooling coil is typically_x000D_
collected in a drainage system and is removed using sloped piping or a condensate pump. Since the temperature_x000D_
of the condensate is close to the temperature of the coil fins, this scenario represents an untapped opportunity_x000D_
for additional cooling. This is typical for heat exchanger units manufactured by Price industries Ltd, a Heating,_x000D_
Ventilation and Air-Conditioning (HVAC) company headquartered in Winnipeg, Manitoba. The objective of_x000D_
the company is to reuse the cold condensate in spray/evaporative cooling application to pre-cool the warm air_x000D_
before it reaches the cooling coil for additional cooling._x000D_
It is expected that this approach would increase the cooling efficiency of the air handling unit. However, the_x000D_
implementation of this concept requires a comprehensive optimization study with respect to the pertinent_x000D_
variables of the spray flow (e.g., airflow velocity, water flow rate, droplets formation (spray) and distribution,_x000D_
etc) in order to maximize the amount of pre-cooling that can be achieved with the condensate. Quantifying the_x000D_
effect of this evaporative pre-cooling on the latent capacity of the cooling coil would be another beneficial_x000D_
component of this study/project._x000D_
The objective of the proposed research is to develop an efficient spray cooling strategy to maximize liquid/air_x000D_
heat transfer of HVAC precooling systems. The resulting improvement in the efficiency of these units will help_x000D_
increase and strengthen the market share of Price Industries Ltd and consequently the Canadian HVAC_x000D_
