Building on prior studies, in this paper, the authors outline additional findings and lessons learned from these preliminary field trials of the GAHP combined space and water heating system, at sites in Tennessee and Wisconsin.
In this section, two active field demonstrations of the GAHP combined space and water heating system are described: * Tennessee (Climate Zone 4A): Installed in early 2016 at a residence in Eastern TN, with monitoring methodology and preliminary results described in a previous paper [Glanville, 2018], the residence is a 1,800 sf (167 [m.sup.2]) single-family home with 4 occupants (three full-time, one intermittent).
Using energy inputs for cooling and heating and the capacities of GAHP at various outdoor temperatures the daily heating and cooling demands of the building were determined from Equation 8 and Equation 9.
Equation 14 gives the natural gas savings (m3) achieved by using GAHP in heating season.
The considered parameters are solar intensity, a filling ratio (amount of liquid charge in evaporator section in GAHP
) and inclination angle by using distilled water as working fluid.
Meanwhile, the hierarchical structure of the effectiveness evaluation index system of the prison physical protection system is preferable in the application of GAHP
to calculate the weight value of each index element.
Further impact can be achieved through scaling-up and leveraging interventions for GAHP
household producers, wet markets and small slaughterhouses, to reach beyond the original geographic coverage of 12 provinces.
"I was motivated to start GAHP
because I was receiving calls from Therapists all over the country asking 'I want to have a Holistic Practice like yours--can you show me how to do it?' GAHP
supports the members to build thriving Holistic Therapy Practices that can transform the lives of hundreds of people using Holistic methods 'while giving them more Joy, Freedom and Income,'" explains Riutta.
In the pursuit of a cost-competitive GAHP
intended for residential retrofits, hydronic or forced-air heating distribution systems, the authors developed and demonstrated several prototype air-source GAHPs
through laboratory and early-stage field evaluations with support from a boiler and water heater manufacturer, as described previously (Glanville, 2017).
