Air To Water Heat Pump For Radiant Floor

Air to water heat pumps green building advisor geothermal heat pumps.

Air to water heat pump for radiant floor. That s the situation lance peters faces as he plans a new two story house in ottawa what peters assumes is the u. Remember heat energy always moves from hot to cold so the chilled floors act as a big sponge to absorb hot air from the building. Old construction and would like to add air conditioning. That heat can be transferred to a steam of water or antifreeze solution and supplied to a hydronic radiant panel distribution system at temperatures up to 130f 54c.

A ground source heat pump can be connected to a hydronic distribution system one using hot water for example in floor hydronic sometimes called radiant heat or a forced air distribution system using ducts. I would like to add air conditioning and the ideal unit would also provide a more efficient heat source for the radiant floor system. These are similar to standard air source heat pumps but the outdoor unit has a heat exchanger which heats an antifreeze solution that circulates through the home via an in floor radiant or wall coil and fan system. This is what we used in our seattle zero energy house.

One solution where these desirable traits converge is a low ambient air to water heat pump combined with a low temperature radiant panel distribution system. Let s not forget the advantage and cost. I have radiant floor heat in 5 yr. This sets the table for use of hydronic heat emitters such as radiant floors radiant walls and radiant ceiling panels panel radiators fan coil convectors and even contemporary low temperature fin tube baseboard.

This is done by monitoring the dew set point in the system to avoid condensation. A radiant floor cooling system will not solve humidity issues but installing a large or whole house dehumidifier can do this job very easily at about the cost of an ac. A hydronic air to water heat pump is the easiest way to maximize your home comfort. How an air to water heat pump provides air conditioning our air to water heat pump is known as a fully reversing heat pump.

The only available utility to the site is electricity and the radiant floor is run by a steibel eltron on demand water heater. Future directions include real testing on existing equipment other nonlinear optimization techniques extensions to more energy resources and robustness analysis of the solutions. But because there are no air ducts with a radiant floor system air conditioning must be added separately. Hydronic radiant floor cooling can also be accomplished via radiant floor cooling.

The arctic heat pump now chills a buffer tank and the control system uses the chilled water to remove heat energy from the floor. It also allows the heat pump system to be configured to provide most if not all of the energy needed for domestic water heating. Current generation low ambient air to water heat pumps can extract useable heat from outdoor air at temperatures down to 8f 22c. From the simulation results it can be concluded that for the air to water heat pump connected to a radiant floor building the suboptimal ltv mpc approach provides quite good results which are fairly close to the optimal one obtained through nmpc algorithm.

Some air to water heat pumps are capable of producing leaving water temperatures of 130f even with relatively cold outdoor air. In my research i have found what appears to. This means that in addition to making hot water for your radiant in floor system it also reverses the refrigeration process to make chilled water. With a suitable heat.

When you say hot water heat pump you are probably talking about an air source heat pump like the daikin altherma.
