Air Source Heat Pump Water Heaters

In the energy climate of today, energy costs continue to increase. Wasted energy has become economically unfeasible for most companies and the need to save the worlds resources is just another responsible reason coming on the heels of sound financial planning.

Energy Engineered Products has developed a full and comprehensive line of equipment to fit the needs of clients with many and diverse requirements.

A Heat Harvester Air Source Heat Pump Water Heater can keep your building warm in the winter and cool in the summer. Our air-source heat pump pulls its heat indoors from the outdoor air in the winter and draws heat from the indoor air in the summer to be rejected outside.

A Heat Harvester Air Source Heat Pump can provide efficient heating and cooling for your building, especially if you live in a warm climate. When properly installed, an air-source heat pump can deliver one-and-a-half to three times more heat energy to a building compared to the electrical energy it consumes. This is possible because unlike conversion from a fuel, a heat pump moves heat from one place to another, rather than converting it.

How it Works

 

You might be wondering how an air-source heat pump uses the outdoor winter air to heat a building. Believe it or not: heat can be harvested from cold outdoor air down to about 40°F. And this can be accomplished through a process you're probably already familiar with—refrigeration.

Basically, a heat pump's refrigeration system consists of a compressor, and two coils made of copper tubing, which are surrounded by aluminum fins to aid heat transfer. The coils look much like the radiator in your car. Like in a refrigerator or air-conditioner, refrigerant flows continuously through pipes, back and forth from the outdoor to the indoor coils. In the heating mode, liquid refrigerant extracts heat from the outside coils and air, and moves it inside as it evaporates into a gas. The indoor coils transfer heat from the refrigerant as it condenses back into a liquid. A reversing valve, near the compressor, can change the direction of the refrigerant flow for cooling as well as for defrosting the outdoor coils in winter.

The efficiency and performance of today's air-source heat pumps is one-and-a-half to two times greater than those available 30 years ago. This improvement in efficiency has resulted from technical advances and options such as: thermostatic expansion valves for more precise control of the refrigerant flow to the indoor coil and variable speed blowers, which are more efficient and can compensate for some of the adverse effects of restricted ducts, dirty filters, and dirty coils.

Our units offer improved coil design, improved electric motor and two-speed compressor designs, and our coil copper tubing is grooved inside to increase surface area and heat transfer..
