Abstract An integrated heat pump and heat storage system comprising a heat pump, a first conduit for supplying return air from an enclosure to the heat pump, a second conduit for supplying heated air from the heat pump to the enclosure, heat storage apparatus, a first damper operative in a first orientation to permit return air from the enclosure to enter the first conduit and to prevent return air from passing through the heat storage apparatus and operative in a second orientation to cause return air to pass through the heat storage apparatus for being heated thereby before entering the first conduit, a second damper operative in a first orientation to cause heated air from the second conduit to pass through the heat storage apparatus for giving up a portion of its heat for storage and operative in a second orientation to prevent heated air from the second conduit from passing through the heat storage apparatus and to permit the heated air from the second conduit to reach the enclosure. The heat storage apparatus may comprise phase change materials.
An integrated heat pump and heat storage system comprising: a heat pump; a first conduit for supplying return air from an enclosure to said heat pump; a second conduit for supplying heated air from said heat pump to said enclosure; heat storage means selectably communicating with said first and second conduits; first damper means operative in a first orientation to permit return air from said enclosure to enter said first conduit and to prevent return air from passing through said heat storage means and operative in a second orientation to cause return air to pass through said heat storage means for being heated thereby before entering said first conduit; and second damper means operative in a first orientation to cause heated air from said second conduit to pass through said heat storage means for giving up a portion of its heat for storage and operative in a second orientation to prevent heated air from said second conduit from passing through said heat storage means and to permit heated air from said second conduit to reach said enclosure.

An integrated heat pump and heat storage system comprising: a heat pump; a first conduit for supplying return air from an enclosure to said heat pump; a second conduit for supplying heated air from said heat pump to said enclosure; heat storage means selectably communicating with said first and second conduits; first damper means operative in a first orientation to permit return air from said enclosure to enter said first conduit and to prevent return air from passing through said heat storage means and operative in a second orientation to cause return air to pass through said heat storage means for being heated thereby before entering said first conduit; and second damper means operative in a first orientation to cause heated air from said second conduit to pass through said heat storage means for giving up a portion of its heat for storage and operative in a second orientation to prevent heated air from said second conduit from passing through said heat storage means and to permit heated air from said second conduit to reach said enclosure.
Claim 3
Dependent Claim
61 words
A system according to claim 1 and wherein said first damper is operative when in its second orientation to prevent return air from directly entering said first conduit and said second damper is operative when in its first orientation to prevent heated air from said second conduit from directly passing to said enclosure without first passing through said heat storage means.
Claim 4
Dependent Claim
19 words
A system according to claim 1 or claim 2 and wherein said heat storage means comprises phase change materials.
