The refrigerant loop comprises a compressor (1), a four-way valve (2), a first heat exchanger (3), a first check valve (4-1), a second check valve (4-2), a third check valve (4-3), a fourth check valve (4-4), a first solenoid valve (5-1), a second solenoid valve (5-2), a liquid reservoir (6), a desiccant filter (7), an electronic expansion valve (8), a finned tube heat exchanger (9), a gas-liquid separator (10), and a heating-type water storage tank (12). The hot water loop comprises the heating-type water storage tank (12), a filter (13), a water pump (14), a nozzle (15), an electric heating tape (16), a water collection pan (17), a three-way valve (18), a temperature sensor (19), and a liquid level sensor (20), wherein a three-way valve first input end (18a), a three-way valve first output end (18b), and a three-way valve second output end (18c) are provided on the three-way valve (18). The air loop comprises the finned tube heat exchanger (9) and a fan (11). Said device spends less time and consume less heat for defrosting, so that continuous heat supply during the defrosting can be realized, and the heat supply time and the heat supply efficiency of the heat pump system are improved.

The invention provides a multi-agent power generation optimization scheduling method based on reinforcement learning. With the goal of maximizing the total operation benefit, a multi-agent complementary optimization model is established; based on the established multi-agent complementary optimization model, a multi-agent game is constructed. Model, according to the Nash game theory, the local optimal strategy under the mutual coordination of each agent is obtained, and the local optimal strategy set is constructed; the Q-learning algorithm is used to solve the optimization problem, and the global optimal is obtained, which is the optimal strategy set π * According to the idea of ​​combining Nash game and Q-learning algorithm, this method can transform the multi-agent optimization problem of complex system into a state-action value function convergence problem, and obtain the best optimization scheme, reduce the complexity of optimization scheduling, and reduce the complexity of optimization scheduling. It can realize model-free optimization and achieve the purpose of energy saving and high efficiency.
