Now when using one of the given heat pump models given in TRNSYS, lets say using the water to water heat pump type 927. By default the </span><span style="background-color: transparent;">Rated cooling and heating capacity per heat pump is 8.33 kW
with </span><span style="font-size: 10pt;">Rated heating and Cooling power per heat pump of 1.33 kW.</span></div><div style="color: rgb(0, 0, 0); font-size: 10pt; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span style="background-color: transparent;"><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13.63636302947998px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span style="background-color: transparent;">If I want to model the 125 kWth heat pump using the type 927, is it a matter of changing the Rated cooling and heating capacity per heat pump to 125kWth and the Rated heating and cooling power per heat pump to 18 kW? </span></div><div style="color: rgb(0, 0, 0); font-size: 13.63636302947998px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent;
