Ses­si­on 9: Ven­ti­la­ti­on and hea­ting

Diens­tag, 14. Sep­tem­ber 2021

 

Die Nut­zung ei­ner Wär­me­pum­pe kann einen zen­tra­len Bau­stein für den er­folg­rei­chen Be­trieb ei­nes Pas­siv­hau­ses dar­stel­len. Im Lich­te der stei­gen­den At­trak­ti­vi­tät von Pho­to­vol­taikstrom bie­ten die­ses elek­trisch be­trie­be­ne Sys­tem zur Er­zeu­gung der be­nö­tig­ten Hei­z­ener­gie und Warm­was­ser­er­zeu­gung ei­ne at­trak­ti­ve Mög­lich­keit, ei­nem grö­ße­ren An­teil des selbst er­zeug­ten Stroms zu nut­zen. Ver­bes­se­run­gen al­ler Art auf die­sem Ge­biet im Be­reich der Lüf­tungs­pla­nung so­wie Ratschlä­ge und Er­fah­rungs­be­rich­te zur Pla­nung und Durch­füh­rung ent­spre­chen­der Pro­jek­te wer­den von den Re­fe­ren­ten de­tail­liert prä­sen­tiert.

Ven­ti­la­ti­on sys­tems com­bi­ned with he­at pump for hea­ting, coo­ling and do­me­stic hot wa­ter

High­ly ef­fi­cient ven­ti­la­ti­on with he­at & hu­mi­di­ty re­co­ve­ry is man­da­to­ry in PH buil­dings. Ven­ti­la­ti­on sys­tems com­bi­ned with a he­at pump for hea­ting and coo­ling & de­hu­mi­di­fi­ca­ti­on are the con­se­quent fur­ther de­ve­lop­ment of the clas­sic 'com­pact unit' for Pas­si­ve Hou­ses, which are a well ad­op­ted so­lu­ti­on for apart­ments in mul­ti-fa­mi­ly buil­dings, too.

The ap­p­li­ca­ti­on of am­bient loop dis­trict hea­ting in mul­ti-re­si­den­ti­al Pas­si­ve Hou­ses

This pa­per dis­cus­ses the po­ten­ti­al of 5th Ge­ne­ra­ti­on am­bient loop de­sign in low ener­gy Pas­siv­haus de­sign. We shall dis­cuss sys­tems and their ad­van­ta­ges and di­s­ad­van­ta­ges over tra­di­tio­nal 4th Ge­ne­ra­ti­on hea­ting tech­no­lo­gies.

Iso­la­ti­on en­vi­ron­ments: How Pas­si­ve Hou­se = Pas­si­ve He­alth

By re-thin­king the way he­al­th­care fa­ci­li­ties are de­si­gned bet­ter care can be pro­vi­ded to  oc­cu­pants, ener­gy and ven­ti­la­ti­on sys­tems can be used mo­re ef­fi­cient­ly and hu­man, as well  as ca­pi­tal, cost is sa­ved in the long term. The Pas­si­ve Hou­se stan­dard can re­spond to  CO­VID-19 whi­le not igno­ring cli­ma­te change as it al­lows for ho­li­stic buil­ding de­sign.  

11.25 Uhr

Ex­pe­ri­ence of air to wa­ter he­at pumps for sin­gle fa­mi­ly pas­siv­haus dwel­lings

Mo­ni­to­red ener­gy use of air to wa­ter he­at pumps in sin­gle Pas­siv­haus dwel­lings is com­pa­red with the de­sign es­ti­ma­tes using PHPP. He­at pumps using con­ven­tio­nal HFC ref­ri­ge­rants are com­pa­red with CO2 ref­ri­ge­rant. The lat­ter ga­ve im­pro­ved per­for­man­ce for hot wa­ter hea­ting but si­gni­fi­cant­ly wor­se for space hea­ting. This is due to the ve­ry low he­at load of Pas­siv­haus dwel­lings being be­low the nor­mal out­put ran­ge of avai­la­ble he­at pumps.

11.40 Uhr

De­ve­lop­ment of a mo­du­lar he­at pump with com­pact and si­lent faça­de-in­te­gra­ted out­door unit

A mi­ni-split he­at pump with faça­de-in­te­gra­ted out­door unit was de­ve­lo­ped thanks to CFD si­mu­la­ti­ons and la­bo­ra­to­ry mea­su­re­ments. The first test of a func­tio­nal mo­del of the he­at pump pro­ved pro­mi­sing, but an is­sue re­la­ted to a leaky four-way val­ve must be sol­ved to fur­ther in­cre­a­se the per­for­man­ce.
