In this study a small ammonia ground source heat pump with a capacity of 8,4 kW has been designed to provide space heating and hot water preparation with estimated max heat load of 7,5 kW for space heating and 2 kW for hot tap water preparation. The main components and materials have been chosen to avoid corrosion and to be compatible for work with ammonia. Calculations with engineering equation solver (EES) have been done to estimate heat pump performance and evaluate the necessary size of the water tank for the heating system.
