An oil separator is an accessory used on some larger refrigeration systems to help limit the amount of oil in circulation. It is typically used on low temperature applications where the refrigerant’s mass flow rate is low. But it could be used on any system.
The HVACR industry is one where both centrifugal pumps and fans are used on an ongoing basis. Because of this, HVACR systems are huge energy consumers. Creating higher-efficiency systems offers a tremendous opportunity for great electrical and monetary savings. Many of these savings can be achieved through the use of variable-frequency drives.
With more than 1 million sealant applications now sealing and preventing leaks in air conditioning/refrigeration systems worldwide, the odds are high most service techs will be confronted, if not already, with recovering refrigerants that have sealants in them. A common question is whether recovered refrigerant/sealant combinations will clog manifold gauges, recovery machines, etc.
Any contractor who wonders whether air curtains can prevent vehicle emissions and cold winter air infiltration at restaurant drive-through window stations needs to talk to Jessica Varga, an employee at Arby’s store No. 5775.
How many HVAC contractors do you know who have professional saleswomen in their company? I mean specifically professional saleswomen who are going into homes and sitting across the table with homeowners to discuss their home comfort needs. Probably not many, if any at all. So why are there so few women in HVAC sales?
With homeowners becoming more interested in tightening their homes, and awareness and opportunities increasing due to federal and local incentives, IAQ problems could be addressed from the start by introducing more fresh air, according to Nelson Warner, vice president of R&D for Tamarack Technologies Inc.
As contractors step up their willingness to use the reclamation option to offset decreasing supplies and increasing costs of virgin HCFCs, especially R-22, they are entering a sector of the market with especially complex chemical processes designed to produce refrigerants just as good as virgin HCFCs.
When you talk about air distribution with Tom Godby, it’s all about zoning. “It’s something that gives you the opportunity to do some redesign in houses,” said the founder and chairman of Godby Heating and Air Conditioning, Indianapolis. Godby calls zoning “a natural step to take for a contractor.”
Using ultraviolet (UV) energy to destroy biological contaminants may be rooted in science, but the question we must ask is, how do we deliver the UV intensity needed to destroy the biological contaminants that may be traveling through the building’s ventilation system, or the mold growing on the evaporator coil?
Discussions of the economic recovery often include talks of a so-called green economy. According to Wikipedia, this includes “green energy generation based on renewable energy to substitute for fossil fuels and energy conservation for efficient energy use.” Many see it as a kind of New Deal. Today’s “green deal” offers opportunities to save energy on a significant magnitude.
