Our AC compressor is located on the south side of our Florida home and it seems to me that if it were shielded in some way it would not have to work as hard - is this correct?

Today, air conditioning is one of the world's largest consumers of electricity, greatly impacting global emissions of CO2. The consumption of energy peaks when the sun provides the earth with the most heat. Therefore, it is obvious that we use solar energy to drive the water cooling system, thereby minimizing the electricity consumption of the AC unit. We turn solar heat into cooling with a minimum use of electrical power. With a combination of low pressure turbines and using water as refrigerant our pantented technology creates efficient cooling from solar heat featuring: 90% savings on electric power 85% reduction in carbon emissions No chemical refrigerants - only water AC-Sun's mission is to bring this thermal air conditioning solution driven by solar panels to the market.

Busch backed the school system, accusing the board majority — Gov. Larry Hogan and Comptroller Peter Franchot — of intruding on the powers of the General Assembly.

He said lawmakers could review the board's role during next year's legislative session. In a letter dated Monday, acting school system Chief Executive Officer Tammy L. Turner said the position the board took last week was surprising because the city had submitted a "good faith plan" spelling out its intention to install air conditioning throughout its schools.Because of the board's action, she said, the system will be "forced to choose between much-needed fire safety, roofs, boilers, and window projects that are essential to the safety and security of our students, and the BPW's unprecedented mandate to install portable air-conditioning units within an unreasonable time frame."best ac unit for arizona Peter Hamm, a spokesman for Franchot, dismissed the letter."average cost for new ac unitFor five years, the comptroller has been asking the education bureaucracy in Baltimore City to step up and do the right thing by thousands of children who are sitting in unsafe and unhealthy classrooms. central air conditioner size needed

And all we've ever received have been promises followed by excuses," Hamm said.The three-member board voted 2-1 last week to withhold $5 million from Baltimore and $10 million from Baltimore County in an effort to force the two school systems to install portable air conditioning in classrooms that aren't currently cooled. The board set the start of the school year as its deadline.The systems, which include some of the oldest school buildings in the state, contend they have plans to install central air conditioning over the next few years. But Hogan and Franchot said it is imperative to add air conditioning now. The dispute came to a head last week during a contentious board meeting, at which Hogan, a Republican, and Franchot, a Democrat, castigated school officials from the two jurisdictions for not installing air conditioning more quickly.Over the protests of Treasurer Nancy K. Kopp, the governor and comptroller voted to "fence off" the money so that the city and county could not use it for other construction work.

Kopp, a Democrat, called the move "political theater" and said it was probably illegal for the board to force its priorities on local school systems.The board's action prompted David Lever, the longtime executive director of the Interagency Committee on School Construction, or IAC, to submit his resignation in protest.The committee, an independent agency that recommends which school construction projects should be funded, has long followed a policy that makes portable air conditioners — as opposed to central air — ineligible for state funding. Hogan and Franchot have sought to overturn that policy, while the General Assembly wrote it into law in this year's capital budget.In its letter, Baltimore schools said the cost of installing window air conditioners in 2,000 classrooms would come to $27 million. "The district does not have additional resources to fund such an aggressive program," Turner wrote.Hogan spokesman Matthew A. Clark called the letter "alarming," adding that the city schools had previously told the state that only about 400 classrooms lacked air conditioning, with a cost of $4 million to install them."

It's obvious that more attention must to be paid to the matter given the scale of the problem," he said.Busch, an Arundel County Democrat, said in an interview Tuesday that the legislature is likely to address the board's powers when it convenes in January."I think there'll be some extensive study on defining the roles of the IAC and the Board of Public Works," he said.Busch said the board's role is to review and approve state contracts, not to make policy. He said the board's action sets a "bad precedent" that could allow it to withhold money from school districts any time it disagrees with them on policy, including curriculum.Hamm, speaking for Franchot, brushed off Busch's criticism."The speaker is a very, very important man. He has a lot of important matters to work on. Tell him we've got this one covered," Hamm said.Trees and awnings can provide adequate shade for your air conditioner. The energy costs of a window unit air conditioner or a central air system tend to rise as temperatures go up, but you can limit the demands on your unit by shading it.

An air conditioning unit operating in the shade uses less energy than one placed in full sun; this is because the air around it is much cooler, therefore, it doesn’t require the unit to work as hard to provide cooled air. Shading Walls, Windows and Air Conditioners Deciduous trees with high, spreading foliage and crowns that are planted on the south side of your home provide ample shade for both the roof and the air conditioning units below it. Trees lower to the ground are ideal for east and west sides of your home, where shade is needed at lower angles during the morning and afternoon. Deciduous trees block heat in the summer, but allow the sun to warm your home during the cooler winter months. Evergreen trees and shrubs provide continuous shade and block high winds. Planting a 6- to 8-foot deciduous tree on the south side of your home provides shade during the first year after planting. On the Ground Plan your landscaping to accommodate your air conditioner and to cool your home. The ground and pavement around your air conditioner absorb heat, and this heat radiates into the cool air above it.

By shading the ground and pavement, you ensure the air is cooled before it reaches your home’s walls and windows. You have several options for ground shade, such as a large bush or row of shrubs along a patio or driveway. Plant low hedges as shade for walkways, or install a trellis and fill it with climbing vines to shade a deck or patio area. Maintain Airflow When shading your air conditioner, whether it is part of a central air system or a window unit, ensure the air conditioner has adequate airflow. Planting trees, shrubs and other vegetation so thick that air cannot flow around the unit reduces the benefits that shading provides. Make sure there is a minimum of 2 feet of clearance around the air conditioner and about 5 feet of clearance above it. If it is not possible to provide this clearance because of heavy vegetation or the presence of other structures, it is safer not to shade the unit. Instead, place it in a location that limits direct sunlight. When Landscaping Shade Isn't Possible If you’re installing a window air conditioner, place the unit in a window on the north-facing side of the house whenever possible.
