Abstract :
In order to solve the problem of the soil heat imbalance due to the year-round operation of the solar-ground source heat pump in regions with the large gap between cooling and heating loads, this paper proposes to collect and store solar energy in the soil in the transition season. Based on the heating and cooling design of a solar-ground source double effect LiBr-H2O absorption heat pump for an office building, the heat pump system considering the solar energy stored in the soil has been built on TRNSYS platform. The long-term operating simulation has been conducted. The soil-based energy storage effect has been evaluated with taking the soil heat balance as the objective. The necessity of using the soil-based energy storage in the transition season has been discussed based on dynamic performance analysis results. The results show that the average soil temperature in the single heating condition rises to 16.49 degrees C, which is stable around 15 degrees C in the double cooling and heating condition after 10-years operation. The soil heat imbalance rates under two conditions are 18.32% and 11.64%, respectively. It can be seen that soil heat imbalance can be solved by the soil-based energy storage in the transition season.

Abstract :
This paper takes the independent-developed special parabolic trough collector for the air-conditioning and the double-effect absorption chiller to build a solar cooling system, and simultaneously utilizes the ground heat exchanger(so-called SGAC system) to replace the traditional cooling tower as the heat exhausted side(so-called SAC system) in summer. The simulation model of SGAC is established on TRNSYS. The simulation calculation is performed for the building cooling during the whole cooling season in Beijing. The research results indicate that SGAC has a good stability and high efficiency during the whole cooling season. The performance comparison of SGAC and SAC has been carried out. The economy of SGAC system should also be considered in the determination of the main design and operating parameters. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

Abstract :
In this paper, an independent-developed solar parabolic trough collector (PTC) for solar air conditioning has been adopted in a solar air conditioning system with a three-phase accumulator. The composition and operation strategy of the system are elaborated in detail. In view of the measured data of the solar energy and the cooling load demand of buildings, the reasonable matching design of the solar collector, absorption refrigeration chiller and three-phase accumulator is carried out. On this basis, the dynamic performance of the solar air conditioning system with the independent-developed PTC is analyzed. The calculation and analysis results show that the solar air conditioning system with a three-phase accumulator can continuously and steadily supply cooling for buildings day and night. Cooperative operation of the solar absorption refrigeration with the PTC and the three-phase accumulator can not only improve the efficiency of the parabolic trough collector, but also ensure the high energy storage efficiency of the three-phase accumulator. The average parabolic though collector efficiency is 67.5%, the energy storage efficiency of the three-phase accumulator is 0.8, the solar fraction can reach 82.4%. Based on the economic analysis, the investment of the solar air conditioning system with a three-phase accumulator is acceptable. (C) 2020 Elsevier Ltd. All rights reserved.

Abstract :
The developing and utilizing of the renewable energy in the field of the building air conditioning is one of the effective environmental protection ways. This paper conducts the comprehensive environmental impact assessment of an absorption solar-ground source heat pump(ASGSHP) and a vapor compression ground source heat pump(VGSHP) using the life cycle assessment (LCA) method. The three stages in the whole life cycle, i.e., the manufacturing, transportation/installation and operation phase of these two systems which meet the cooling demand of an office building in Beijing are analyzed, respectively. The comprehensive environmental assessment indexes including the pollutant emissions, the global warming potential(GWP), the acidification potential (AP), the dust potential and the environmental impact load(EIL) in the whole life cycle of the two systems are calculated and compared with each other. The environmental impact load, GWP, AP and the dust potential of the ASGSHP can be reduced by 42.20 %, 38.66 %, 45.73 %, 42.71 % compared with the VGSHP, respectively. The research results can provide the basic data and theoretical guidance for the further development and utilization of the GSHP system.

Abstract :
A new combination system of "three-phase energy storage" and solar absorption refrigeration has been developed in this paper. The operation process of LiBr-H2O three-phase energy storage system is described in detail. Thermodynamic analysis models of charging/discharging processes based on the absorption principle are established in order to understand the dynamic characteristics of three-phase energy storage and release processes. The dynamic simulations of charging/discharging processes are carried out by using MATLAB. The influences of operation parameters on the characteristic parameters of three-phase charging/discharging are analyzed, and the performance evaluation indexes of three-phase energy storage system are obtained. The simulation results showed that the lower initial concentration of LiBr-H2O solution, the smaller mass flow rate of LiBr-H2O sprayed on the heat exchanger in the energy storage tank and the higher heat conductance of the heat exchanger (KA) result in the higher energy storage efficiency and energy storage density. The smaller mass flow rates of LiBr-H2O and the cooling water can make the more stable discharging process with longer cooling time. The research results can provide theoretical guidance for further improving and optimizing the operation performance of three-phase energy storage system coupling in solar air conditioning.

Abstract :
A new ice-storage experimental system with a closed (CIST) and an open (OIST) ice-storage tank has been exploited, with which the external ice melting processes are studied experimentally. Furthermore, the researches on combinations of external and internal ice melting have been carried out. The experiments indicate that the cold release rate of CIST is more stable than that of OIST under the same conditions, especially, the cold release rate of OIST decreases significantly at the later stage of the discharging process. The outlet temperature of the discharge water flowing from the bottom-to-top (Mode 1) is lower than that from the top-to-bottom of the ice-storage tank (Mode 2). With the relatively lower volumetric-flow rate, the outlet temperatures of the discharge water rise slowly, meanwhile, the cold release rate is also relatively lower. To solve the problem of "millennial ice" in the external system without an air-agitation device, two types of the combination of external and internal ice melting have been adopted, one is to adopt internal ice melting at first, and then external ice melting, the other is to adopt simultaneously the internal and external ice melting. The experiments show that the cumulative discharging capacity of the latter has been significantly improved. (C) 2019 Elsevier B.V. All rights reserved.

Abstract :
Based on a quasi 3-D steady model inside and a 2-D unsteady model outside of the borehole of ground heat exchanger(GHE), the relationship between the heat exchange rate per depth of borehole and main parameters (center-to-center distance of two branch pipes, radius and depth of the borehole) has been analyzed. The rational values of those design parameters with considering the heat exchange rate per depth of borehole are obtained. The dynamic simulations of underground temperature field (UTF) of single-pipe and pipe-group of U-tube GHE have been conducted by ANSYS. The change rules of UTF are obtained when ground source heat pump(GSHP) has experienced a complete cooling and heating cycle during one year. The simulation results of a single-pipe show that the action radius of borehole is 1.9 m, i.e., it is reasonable that the borehole center-to-center distance is 3.8 m. The simulation results of pipe-group indicate that temperature of the soil center encircled by four boreholes at the beginning of heating in winter is higher than the initial temperature of soil, but it is in opposite for cooling in summer, which is beneficial to the efficient operation of GSHP. This work can provide guidance for the rational design and operation of GSHP. (C) 2019 Elsevier Ltd. All rights reserved.
