    Description

    Using High Efficiency CO2 Heat Pump Water Heater System Section

    1. Energy saving 5 times more efficient than traditional electric water heaters.

    2. Allow off-peak electricity use

    3. Higher first hour rating than all heat pump water heaters

    4. Faster recovery after pumping hot water

    5. Hot water production down to -20°F and below

    6. Provides hot water temperatures up to 175°F

     

    How the CO2 Heat Pump Water Heater System Works

    A CO2 heat pump water heater is a two-part system that includes a tank (usually placed indoors) and a heat pump unit (usually placed outdoors, up to 66 feet from the tank). A heat pump works like a reverse air conditioner, drawing thermal energy from the atmosphere and applying it to the water in the tank.

     

    A CO2 heat pump water heater works the same as a conventional heat pump, except it uses carbon dioxide as the refrigerant. Due to the unique properties of CO2, CO2 heat pumps operate very efficiently over a wide temperature range. It is capable of extracting heat from the air all the way down to -20°F and above in one heating stage, raising the water temperature to 150°F at a rate of 0.3 gal/min. The result is a system that requires significantly less electricity to heat water than conventional hot water systems, and operates without backup coils in a very wide range of climates.

     

    While a CO2 heat pump water heater system is perfect for replacing an existing gas or electric hot water tank in any residential or multi-family application, the ability to operate at low outside temperatures and still provide hot water at 150°F means the same system can be All solutions for today's new low-energy homes.

     

    CO2 heat pump water heaters use carbon dioxide as a refrigerant, which is harmless to ozone and does not contribute to global warming

    Heat pumps use a small amount of energy to transfer heat from one location to another. In a heat pump system, the heat in the air is absorbed by the natural refrigerant CO2, which is ozone friendly and does not contribute to global warming.

     

    Warm gaseous refrigerant circulates through the system through a compressor. As it passes through the compressor, its pressure rises and so does its temperature. This hot refrigerant then passes through a heat exchanger to heat water, which is then sent to a storage tank.

     

    Combination system: DHW plus space adjustment

    CO2 heat pump water heaters are capable of delivering 15,000 btu/hr and can be designed as a system providing all domestic hot water (DHW) as well as hot water for space conditioning. This is through one loop to power the DHW mixing valve to lower the temperature to 120°F and the other loop to provide a standard heat exchanger to power hot water radiators, radiant panels or forced air fan coils.

     

    For homes with a design temperature of 12°F or higher and a heat load of 8kbtu/hr or lower, this can be the entire DHW and space conditioning system. Additional on-demand water heater systems can be added to designs for homes with larger heat loads, or a backup system can be used to provide extra capacity for extreme weather events or large homes where the default heat pump system is used for all but the coldest days. can provide.

     

    Multifamily domestic hot water project and new 119 gallon tank

    The efficiency of CO2 heat pumps is attractive for new multifamily projects, but 43 and 83 gallon tanks are difficult to fit into buildings due to space constraints. With new 119- to 505-gallon tanks, that changes. Over the past few years, large building designs have been developed and tested combining these units into heat pump arrays serving larger primary storage.

     

    Frequently Asked Questions about CO2 Heat Pump Water Heaters

    1. What is the operating temperature range of the heat pump?

    CO2 heat pumps operate at temperatures from -20F to 110F

    2. What unit sizes are available?

    The outdoor unit is only one size, but can feed different sized tanks. We offer 43 gallon, 83 gallon and 119 gallon hot water tanks.

    3. What is the coefficient of performance (COP) of the three-electric system?

    It ranges from 2 to 5 depending on the ambient temperature. As the weather gets warmer and the incoming water gets cooler, you'll see greater efficiency.

    4. Can CO2 heat pumps be used as a combination of domestic hot water and radiant heating systems (Combi)?

    Of course. Your heat load must be below 8,000btu/hr and the design temperature is above 12F, we recommend that you use at least 20 gallons of domestic hot water per day to maintain tank stratification and efficiency.
