Heat pump
Enclose the heat pump in a sun house | |
I understand my heat pump becomes horribly inefficient in very cold weather. Assuming the heat pump is in the sun, I could enclose it in a 'house' made of heavy guage clear plastic or plexiglass so the air it is using has been heated some already. What I am unsure of is the volume of air circulated
by the heat pump compared to how quickly the sun house would heat the air. Too small a house would use the warmed air too quickly while too large a house would not heat the air to be any benefit.
Do I have something here, or what?

As your pump runs it will rapidly
cool the air inside the sunhouse as
it takes the heat energy into the
dwelling. |
|

You seem to be suggesting a
plexiglass-and-air solar collector
in this case. Maybe better to use an
existing solar collector directly. |
|

If the sun house is an actual sun
house...then it might be quicker to
just open the doors to let the warm
air into the dwelling directly ;-) |

Just move it inside the house where it's nice and warm. (kidding) |

What [timbeau] said. It would "air-condition" the little sun house very quickly. Maybe set the outside part of the unit in a parabolic reflector? |

[half] solar collector == parabolic
reflector. |

These are used to focus sun's
energy on the 'hot' side of the heat
pump. |
