Overview
The Greenspeed Heating Hours Calculator is a sales tool to help graphically show the heating benefits and cost savings potential of the Greenspeed Heat Pump system for different unit size selections. One page shows the heating and cooling bin hours of the selected location, the other screen shows the heating capacity, balance point, and operating hour differences between a standard heat pump and a Greenspeed heat pump.
Using the Greenspeed Heating Hours Calculator:
The user first selects the state, nearest city, and heating design temperature from drop‐down menus. This displays a graph of the bin hours for the selected city. The bin hour graph helps to show that there are typically more heating hours than cooling hours in most cities, and helps tell the story of the importance of heating efficiency compared to cooling efficiency.
The user then clicks on the Heating Capacities button above the bin hours graph and inputs the heating and cooling loads for the particular structure.
This screen allows the user to select a heat pump size for both the Greenspeed and standard heat pump, and compare the amount of hours the Greenspeed can satisfy the load without the need for auxiliary heat. When up‐sizing the Greenspeed unit per factory recommendations, it becomes clear that the Greenspeed system can delivers much more heating performance than a standard system, while not being over‐sized for cooling.
The user can then create a color print out of both graphs by clicking on the Create PDF button. This tool will aid the sales person by graphically showing the heating benefits of the Greenspeed system over a standard
heat pump in the customer’s particular weather zone. By showing how the Greenspeed system satisfies the heating load with less dependence on auxiliary heat, the sales person can more effectively build the efficiency and cost savings story for the Greenspeed heat pump.
