Testimonials We had two other competitors for control systems. TechCold had a great price and great service. In 2010, we will be building a 4Plex and will be putting a new TCI Pro-Act XP Control System in the new facility. - Ms. Debbie Allen, Facilities Manager, Quispamsis Memorial Arena, Quispamsis, NB The staff from (TechCold) has been a pleasure to deal with. They have gone out of their way to give all four of the City of Fredericton arenas, all of which have Pro-Act Arena Controllers, prompt and efficient service…….The Controller was installed as an energy saver and has accomplished that task very well. We have calculated that we have received energy savings in the range of 25%. - Mike Murray, Facility Manager, Lady Beaverbrook Arena, Fredericton, NB Since we installed the TCI Refrigeration Control System, it has made life a lot easier for the refrigeration operators. The refrigeration plant is so stable now. This frees up a lot of time for the operators to do other things. We were able to cut down on the operator coverage, which is a substantial yearly savings. We have a lot of peace of mind with the TCI System. I can tell with one glance how the plant is running. - Bob Simpson, Chief Engineer, Atlas Cold Storage, Toronto, ON We are very pleased with the operation and service of our TCI refrigeration Control System. The system runs very smoothly, and we are already seeing significant energy savings. Our discharge pressure is constant and we are experiencing fewer and shorter defrost cycles. Our refrigeration engineers find the interface controls very user friendly and helpful in monitoring our processes. - Mark Ingerman, Grand Bank Seafoods, Nfld. The ease of access through PC remote allows regular checking and adjustments, when necessary, from away with a great number of changes available. It integrated smoothly with our system and has greatly improved control features and monitoring abilities. The ability to have power save features has indeed proven itself as well… we have reduced our normal bill by 15-20% on average. - Peter Frye, Bayside Foods Terminal, NB TechCold‘s product and systems knowledge has been extremely helpful. Even more important to us has been the extensive “hands on” familiarity and experience in the area of industrial refrigeration. – Joel McLaughlin, Paturel International We have found TechCold to be a highly dedicated and professional company with a strong drive to deliver a fully integrated quality solution. We found the staff at TechCold to be very knowledgeable of the refrigeration plant and very willing to work with ourselves and a refrigeration consultant to achieve a very successful project. We very much look forward to working with TechCold in the future and would recommend their system to any potential customers. - Charlie Francis, Technical Director, Eltek Systems Ltd
TechCold SolutionsEvaporator Control:• Discharge pressure reset during hot gas defrost in order to allow reduced head pressure at other times• Zoned control through separate temperature indications allow “load shifting”• Anti-stratification fan control instead of continuous operation• Separate temperature scheduler for each evaporator• Full temperature alarms with time delays• Adjusts the defrost frequency based on run time and time of year• Manual defrost capabilityDynamic Compressor Set Selection:• Screw compressors are inefficient at low slide valve settings, operates the compressors as close to a 100% slide valve setting as possible• Adapts well with variable speed compressorsTCI creates and models all possible sets of compressors in software. When in a period of low volatility, theexisting compressor set can be replaced with one of higher efﬁciency.Dynamic Discharge Control:• Discharge must be high enough for proper process control• Discharge must be as low as effectively possibleTCI floats the discharge pressure based upon the ambient wet bulb conditions and the requirements of thesystem. The pressure setpoint will be automatically reset to insure each evaporator has the proper defrostpressure. Special algorithms prevent over-shoot when discharge pressure setpoint changes. Fixed, 2 speed orvariable speed fan control.
Compressor Capacity Modulation:• Normal lead-lag control often requires more energy than necessary• At times it is best to use two compressors for modulation while at other times, one is best• Incorporates variable speed compressor controlTCI calculates part load ratios and determines which compressor(s) to modulate for maximum efﬁciency.Ongoing TechCold InitiativesDynamic Suction Control:• Too low a suction pressure wastes energy by decreasing compressor COP• Too high a suction wastes energy by increasing evaporator runtime• Suction can be based on the dynamic product or room temperature requirements instead of on a fixed pressureTCI allows dynamic reset of the suction pressure to accommodate the present product or room requirementsinstead of a “worse case” setpoint.Refrigeration Plant Health Indication:• Through real time analysis, TCI indicates abnormalities in the operation of the condenser, compressor and evaporator components such that proactive maintenance can usually restore proper operation and gain maximum savings• Indications of energy use with TCI operation, what it would have been previously and what the potential is for further savings—all in chart form
