nitroglycerin ointment buy online Moisture in grocery stores can lead to condensation, which in turn may drip from the ceiling onto the goods. Lowering the water content in the air will keep the room and surfaces dry, which is making it easier to keep clean and nice in the store. In the freezer storage a dehumidifier can completely remove ice and frost formation. It contributes to a safer working environment for the staff, but also the goods will not be ruined by bad climate. Dehumidified air makes the air pleasant, both for customers to shop in and for staff to work in.
MOISTURE CONTROL IN SUPERMARKETS
practice pepcid uk Supermarkets are a complex environment and standard air conditioning systems are often not effective for the various store configurations. Humidity can effect refrigeration operation and customer purchasing decisions if the store is too cold or because frozen products are not visible or iced up. Humidity is a hidden energy issue. Often over half the store energy is refrigeration and air conditioning, and designs based on first cost can leave a substantial energy legacy for the owner. Desiccant dehumidification offers an array of benefits to store operation energy and comfort, which can outweigh the initial investment.
REDUCED AIR CONDITIONING COIL WORK

DOAS avoid humidity problems and save energy by removing the latent load of outside air, and over drying the outdoor air sufficiently (i.e. 5°Cdp or 30%RH @ 23°C) to absorb the store (moisture) latent load. This avoids the cost of dehumidification of the entire recirculated air stream.
buy topamax using paypal Up to 80% refrigeration case energy is consumed by the condition of the air around the evaporator, and ambient moisture is a significant component. Generally it can be said a reduction in store humidity of 10%RH would save 10% of case energy. (ref ASHRAE handbook 2003 2.3 (fig 1)).
http://bymarkita.com/v2/ Benefits to cases are:
- Reduced energy input
- Reduced latent load (ice ) on evaporators
- Reduced defrost cycles
- Reduce strip or anti fog heaters
- Less ice and condensation on product
- Reduced product loss due to defrost
Reheating of overcooled air is a traditional low cost practice to allow air-conditioning plant to dehumidify to dewpoint (ie 12°C) and re-heat the air back towards room temperature. Part load conditions often see ventilation loads creating a need for dehumidification but little or no sensible cooling, so overcooling becomes more wasteful. This practice was restricted in 1999 and later banned in USA by building energy standard ASHRAE90.1 and countries like Australia have banned the use of electric elements for reheat.
Stores are often too cool due to the refrigeration case spill loads, the heaters are inclined to be on continuously to maintain comfort temperature neutralise the spill and over cooling.
A Supermarket with electric reheat capacities of around 150kW and a continuously running heater element can cost 150 x $0.10/kWh x 365 x 24 = $US134,000.
Desiccant dehumidification offers an array of benefits to store operation energy and comfort.
Desiccant dehumidification has had substantial application into supermarkets in humid climates due to operating and compliance requirements of the case manufacturers, and the inability of conventional HVAC to dehumidify effectively. With energy consideration now prevalent, the low first cost electric reheat systems are being responsibly designed out.
