Improving Indoor Air Quality On The Casino Floor

For casinos, maintaining guest comfort can be a challenge, especially when the indoor air is filled with smoke. Keeping this air clean means using large volumes of outdoor air, typically around 20 or more air changes per hour. Cooling and dehumidifying this air in warm, moist climates or heating it in cooler climates can lead to a huge energy bill. This unit uses energy recovery to reduce energy costs and both hot and chilled water coils to keep guests comfortable.
