precooloing-setupPre-Cooling of HVAC & Refrigeration Units through Evaporative Fogging

Why PreCooling is an especially important technology

•    Refrigeration and air conditioning account for up to 70% of a typical commercial building’s energy usage.  Hospitals, fresh produce suppliers and restaurants will have an even greater energy consumption.    

•    HVAC systems and refrigeration units not only run longer under high ambient temperatures - they also draw more power whilst operating.
•    The only method to reduce energy usage is to make the HVAC systems run more efficiently by means of a pre-cooling system

Nozzle Based Mist Cooling Systems

Nozzle Based Mist Cooling Systems

Coldmist Cooling is designed to operate where conventional air conditioning is not practical, possible or simply too expensive. As a derivative of the climate control systems used in livestock cooling applications such as - chicken hatcheries, piggeries and dairies - the design incorporates the injection of water pressurized to 1000 psi through specially designed and patented misting nozzles. The resultant finely atomized 5 micron water droplets, when introduced into the surrounding air  - effectively flash evaporate and reduce the ambient temperature by 10- 12° C.

PRE-COOLING applications :
Coldmist nozzle-based misting system – is customized around the HVAC unit and installed and commissioned according to the demands of individual projects. Water filters and a high pressure pump/controller are integral to this system which will significantly reduce energy usage.

With correctly applied methodology a temperature reduction of up to 12° C is achieved with virtually no increase in humidity. As our partners, we have chosen the Danish company SKOV , international suppliers of highly specialized climate control equipment.

Coldmist offers 2 types of misting nozzle distribution systems:

1. The high pressure SLIPLOCK fogging system which allows for easy installation - without the requirement for special tools  - (components are designed to push-fit together ). This system includes - UV resistant, high pressure nylon tubing rated 1800psi, solid brass misting nozzles fitted with anti-drip adaptors and solid brass misting accessories.

2. The high pressure patented FLEXCLAMP fogging system incorporates stainless steel tubing, stainless pipe joiners and all stainless steel misting accessories.    IMPORTANT : This system requires the tubing to be pre-punched prior to installation.
