A refrigeration system is a combination of equipment connected in a closed circuit. A refrigerant is cycled through this circuit absorbing heat in one space and rejecting it to another. Many different compounds are used as refrigerants, but unfortunately many compounds that make excellent refrigerants can be harmful if leaked into an occupied space. As

CHP, or combined heat and power, is an innovative way of reducing the operating costs of your building by generating a portion of your buildings on-site electrical demand and supplementing heat to your primary heating source and domestic hot water systems. Natural gas is burned in an engine to produce electricity and useful heat. CHP

Historically, the price of energy includes all costs required to supply and deliver that energy to you, whether it is electricity, natural gas, gasoline, etc.  Some of these forms of energy have additional fees associate with them to account for infrastructure such as pipelines or roads.  But pricing does not reflect the effects on the

One of the vital standards all buildings must be designed for is ASHRAE Standard 62.1 – Ventilation for Acceptable Indoor Air Quality. Engineers and Designers use these standards to ensure all areas of any building receive the minimum mandated ventilation rate, also known as fresh or outside air. Modern Heating, Ventilation, and Air Conditioning systems

O.Reg. 20/17: Ontario’s Reporting of Energy Consumption and Water Use under the Green Energy Act, 2009. On July 1, 2017, the reporting of energy consumption and water use will become mandatory in the Province of Ontario. Who needs to report?  Any building over 50,000 ft² or any multi-unit residential building over 10 units. Who is

Standby generators are necessary in many buildings as part of the Emergency electrical power supply and they are used to power a number of life safety devices.  Such devices include the fire pumps, fire alarm, emergency lighting, exit lighting, smoke evacuation and pressurization fans, and the elevators.  The emergency electrical power system along with the

Thermo-electric Refrigeration

Thermo-electric refrigerators (figure 7) due to their high cost and low efficiency are far less commonly used then vapor compression or gas cycle. However they do have their advantages, the adaptability and lack of moving parts/circulating fluid make it ideal for small lightweight applications. As well as applications where leaks of a vapor compression unit
