Thursday, March 10, 2022
As California moves to reduce the effect of burning carbon-based products on air quality and global warming, heat pumps and all electric homes will become enlarge their share of the market. The purpose of this training is to assist in that transformation and help installers select correctly sized equipment. This half day webinar reviews the basic principles involved in selecting residential heat pumps including the basic science behind their operation. The session builds upon the loads calculated on Day one in the ACCA Dry Climate Manual J and S, with Wrightsoft portion of the material. The parameters affecting Heat pump selection and sizing for California climates are covered along with sections from the mechanical code that impact heat pump installation.
The material is designed for HVAC contractors, designers, energy consultants and anyone interested in determining building loads. During the half day session, the residential heating and cooling loads calculated on day one are used as the basis in sizing the heat pump cooling and heating capacities based on design temperatures defined in the Standards and located in the Reference Appendices JA II Section. How heat pumps move energy from air that is cooler than the air within the house is explained. The qualities of air such as heat quantity, basic moisture to determine and select the heat pump size appropriate to cover those loads. Using Manufacturer ‘Integrated Capacity’ charts, design temperatures and bin data table, appropriately sized equipment is selected.
