<div dir="ltr">Hi,<div><br></div><div>Has anyone ever had any experience with modeling a VRF system with individual hot water heaters tied into the refrigerant loop?</div><div><br></div><div>We are debating in the office how this would be handled by an energy modeling program. In the summer you could produce almost free hot water and reduce the condensing unit load. But in the winter you would either need greatly oversized condensing units or auxiliary heat. I'm not aware of this level of functionality in an energy modeling program with domestic hot water heating. We are thinking you would need to perform some amount of calculations by hand with outputs from an energy model...</div><div><br></div><div>Also, has anyone had any positive or negative experiences with this in terms of performance and operations?</div><div><br></div><div>Thanks!<br clear="all"><div><div class="gmail_signature"><div dir="ltr"><p><a href="https://ee70db1b-a-1347254f-s-sites.googlegroups.com/a/antella-inc.com/cadstandards/other/Ant-Logo.jpg?attachauth=ANoY7crK3WoX4hU441SAa703fENBeWmmomx2fSEwMugePrx8z8UbHuYup2eh-hLOT4cCifwEfw-EWAzIKfrb50zUwHPiF0KXB-3KyY35c4CKX9033i50232S12FIWzuqbYM-NB1gCHyMd3lWot8TXxqNnFX24oedBXR2aqSvsFkMhpuy3RH-Ue-69vX4glR7HBtQScw8X_R1KwOLH0bh-eu-g2MF1uuWJ-jeHWzdoOweXgOBm4HdSN4%3D&attredirects=0" target="_blank"><img src="https://ee70db1b-a-1347254f-s-sites.googlegroups.com/a/antella-inc.com/cadstandards/other/Ant-Logo.jpg?attachauth=ANoY7crK3WoX4hU441SAa703fENBeWmmomx2fSEwMugePrx8z8UbHuYup2eh-hLOT4cCifwEfw-EWAzIKfrb50zUwHPiF0KXB-3KyY35c4CKX9033i50232S12FIWzuqbYM-NB1gCHyMd3lWot8TXxqNnFX24oedBXR2aqSvsFkMhpuy3RH-Ue-69vX4glR7HBtQScw8X_R1KwOLH0bh-eu-g2MF1uuWJ-jeHWzdoOweXgOBm4HdSN4%3D&attredirects=0" width="96" height="32"></a><br></p>
