Abstract
The major impediments in adopting in Romania the solution of a building heated with heat pump are the high value of the investment in such a facility and the high cost of electricity compared to that obtained by using methane gas. This makes the payback period of an investment in such a system to be long. To reduce the value of the investment it is important to perform an accurate sizing of the system and to adopt a heating solution that is suitable for use with a heat pump as a heat source for heating. Therefore in this article is presented a solution for heating a building with heat pump. For the solution to be cost effective, it has been adopted in accordance with rigorous sizing of thermal loads for heating and adoption of appropriate solutions for heating. To argue the correctness of adopting such a solution, a comparison calculation was performed for the estimated thermal load and energy consumption for heating the building in two versions namely designing the installations with steady-state methods used in Romania, respectively, using a program of numerical simulation namely TRNSYS.
