Housing starts rose 3.9 percent in November to a seasonally adjusted annual rate of 555,000 units from an upwardly revised number in the previous month, according to the U.S. Department of Commerce. This marked the first upward movement in new home production since August, and was entirely attributable to a nearly 7 percent gain in single-family home building.
Effective pump maintenance allows industrial plants and commercial facilities to keep pumps operating well, to detect problems in time to schedule repairs, and to avoid early pump failures. Regular maintenance also reveals deteriorations in efficiency and capacity, which can occur long before a pump fails.
It’s important to find out quickly if you’re doing anything wrong out in the field. A tech who doesn’t use his booties and dirties a customer’s rug can cost you future business. It’s also important to find out what you’re doing right. A tech who is always polite and professional, even when it’s an urgent emergency job, is golden. That’s why it’s essential to always request customer feedback.
Ingersoll Rand has made energy efficiency a priority by joining the U.S. Department of Energy (DOE) Industrial Technologies Program (ITP) Save Energy Now LEADER initiative. Since implementing a tiered internal energy audit program in 2005, the company has saved more than $4 million in energy costs.
A basic HVAC system shows the application of the Second Law of Thermodynamics. The compressor adds energy to the refrigerant, and it becomes hot, just the way a hand operated tire pump does. Since the compressed refrigerant is hotter than the air blowing across the condenser, the heat will flow to the cooler air. This is a transfer of heat energy out of the refrigerant.
The proposed Employee Free Choice Act (EFCA) was a major concern for employers with workforces that were considering or might consider unionizing because it could bring in a so-called card-check system. EFCA failed to become law, but a recent decision by a regulatory agency could still lead to card check.
The customer’s complaint on this call was an overall overheating of his building. The manager told Bob, “We arrived this morning and the entire building was hot and keeps getting hotter.” He led Bob to the basement where there was a boiler. Bob found that the system had pneumatic controls.
Thermodynamics, as with most concepts in science and physics, is most accurately described using mathematical equations. However, simple explanations, although not perfectly accurate, are sufficient to convey the information needed to understand everyday experiences. This article is an attempt to simplify these concepts.
QwikProducts has announced a partnership with the Home Builders Institute (HBI), the workforce development arm of the National Association of Home Builders (NAHB). The partnership offers specialized HVACR and building maintenance training/certifications from QwikProducts to students in HBI Job Corps programs.
Transpired solar air collector technology, developed at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) back in the 1990s, recently found its way back home and is now an integral part of the comfort heating system of the new Research Support Facility (RSF).
