Trigeneration unit operation - Heat pump unit - glycol parameters

The experiment was conducted to test the operation of the air conditioning unit and heat pump. Both units were hydraulically connected. The heat pump was equipped with an extra heat exchanger (Q2) before the main evaporator. The air conditioning unit was equipped with various heat exchangers (Q3-Q6) that transfer heat between glycol prepared in the heat pump and air to use the energy as efficiently as possible. The studies were conducted for three operational states: turning on the system, stabilized operation, and a sudden change in the heat pump parameter.
