Research projects carried out
Employees of the Institute of Mechanical Engineering carry out many research projects as well as research and implementation projects with other research units both in the country and abroad.
Mini Kiwi
“Development of an optimal post-harvest technology for mini kiwi fruit (Actinida arguta) and a prototype of a non-invasive fruit sorting module (MODOM)”
The project is financed from the funds of the Rural Development Program for 2014-2020 under Measure 16 “Cooperation”, implemented from January 2021. by the end of 2022
The task of the project is to achieve two main goals: 1.developing the optimal post-harvest procedure for these new fruits (including post-harvest temperature regime, sorting procedure and long-term refrigerated storage conditions); and 2. designing and making a prototype of a mini kiwi fruit sorting module non-invasively in terms of the degree of maturity (development and validation of algorithms for assessing the degree of fruit maturity and construction of a fully functional prototype of an automatic sorting device with a vision module).
The works are carried out as part of a consortium which includes, apart from SGGW as a leader, also partners – a mini kiwi grower from the province Mazowieckie, where the storage experiments will be carried out, and the Mazowiecki Agricultural Advisory Center in Warsaw, whose task will be to popularize the results of the project among farmers interested in growing mini kiwi. The authors hope that the results of the project will contribute to increasing interest in this still new crop among fruit growers.
RES Ecological Education Center
The construction of the RES Ecological Education Center will cost almost PLN 2.5 million, with over PLN 2.1 million coming from the National Fund for Environmental Protection and Water Management program called “Ecological education”. The educational base will be built in two years, because the end of the project is scheduled for the end of 2022.
The undertaking will cover the construction of: a demonstration installation for the production of biogas from natural organic substrates, a cogeneration system producing heat and electricity from biogas, and a PV photovoltaic installation with a battery supplying electricity to the Center and the RZD Obory complex. The plans include minimizing the demand for electricity from the local power grid and ensuring energy self-sufficiency of the facilities.
High-efficiency heat pump
“Highly efficient subcritical compressor heat pump with a reduced amount of environmentally friendly refrigerant.”The project implemented under the Intelligent Development Operational Program 2014-2020 is financed by the National Center for Research and Development. The works will take 36 months. The project manager was dr hab. Inż. Paweł Obstawski, Head of the Department of Fundamentals of Engineering and Power Engineering IIM SGGW.
The aim of the project is to develop a construction of a high-efficiency reversible subcritical compressor heat pump of the 10-100 kW series working in the air-water and brine (water) -water system, powered by a natural refrigerant belonging to the A3 group with a GWP coefficient.< 30 and ODP = 0. A significant feature of the device will be the reduced mass of the refrigerant in the thermodynamic system. Ultimately, it is assumed that in the case of a heat pump with a capacity of 10kW-20kW, the weight of the refrigerant will be ≤ 100g / kW, while in the case of devices with a capacity of 20kW-100kW, the weight of the refrigerant in the system will be ≤ 150g / kW.
The device will have a modular design. Depending on the user’s needs, the heat pump will work with three independent modules: a hot utility water module (MCWU), a hydraulic tower (WH) and a heat recovery module (MOC) from mechanical ventilation. This design allows the device to be adapted to various operating conditions, including it will be possible to cooperate with the heat pump with elements of the building’s infrastructure, e.g. with the mechanical ventilation system, recovery of system heat from other installed cooling devices, server rooms, and technological processes, which makes them universal.
The project is carried out as part of a consortium led by the ReBaNo company, responsible for the implementation of tasks related to the creation of pilot units. Thanks to a wide range of nominal power, the device will be dedicated to individual customers, enterprises and public buildings.
