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.}

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.}

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.}
