“…The rising economic development requires an increase in energy consumption, which accordingly leads to the global environmental pollution [48]. Annual comprehensive cost (ACC) and annual carbon emission (ACE) are used to denote the optimization objective of the economic and environmental performance.…”

Coupling renewable energy, electric vehicle and hydrogen storage is an effective way for integrated energy systems (IES) to move toward a low-carbon approach. The uncertainties of wind power, PV power and load demand are considered, meanwhile, a ladder-type carbon trading mechanism is designed, and the model is transformed into a deterministic Mixed-integer linear programming (MILP), while the reliability of spinning reserve power is measured by a proper confidence level. Meanwhile, the objective function is constructed based on the optimization strategy of deviation preference, and two objectives are introduced to optimize the annual comprehensive cost and annual carbon emission. The problem is transformed into a MILP and the optimization of the capacity configuration of this IES is performed. The results show that the IES has advantages in economic and environmental performance. The IES has significant advantages in carbon dioxide emission reduction (CDER); meanwhile, EVs show advantages in CDER and charging cost compared to those in the non-IES. Carbon dioxide emissions in IES are only one-fifth of those of conventional distribution system and the CDER effect is noticeable. Moreover, EV charging cost in the IES is relatively lower, while the CDER effect is an order of magnitude better than that of non-IES.

This paper investigates the energy characteristics of the concentric heat pump. The heat exchanger of the evaporator of the "pipe in pipe" type, through the inner copper tube of which the refrigerant circulates, and inside the outer pipe - the coolant, is placed in a spiral around the compressor, cooling it and at the same time absorbing the heat released by it. The new design improves technical and economic performance. Experimental results were carried out, which confirm the possibility of maintaining the compressor temperature (80-90°C), increasing the heat output and conversion coefficient (COP) by an average of 10-15%. The proposed technical solution makes it possible to improve the energy efficiency of the concentric heat pump due to the absorption of the excess heat from the evaporator in the general heat flow and to reduce the emissions of CO2.

Thr paper presents the results of studies of a two-circuit solar installation with thermosiphon circulation in the winter period. The heat pump is integrated with a conventional solar heating system, in which the temperature of the collected heat is reduced from 20 to 30 °C to increase the efficiency of solar energy collection. The low-temperature heat collected by the solar collector is upgraded using a heat pump to generate high-temperature heat for heating rooms in winter and low-pressure process steam for industrial use in other seasons. The results show that the efficiency of the solar collector has increased by 30.50%, its annual effective opera¬ting time has reached 2000 hours, which exceeds by nearly four times that of a conventional solar heating system. To compare the effectiveness of the two options, the tests were carried out under the same climatic conditions on the same day day, from 12 to 15 hours, when the air temperature and the intensity of solar radiation are most stable.
