“…Ensuring proper cooling conditions requires designing cooling devices with optimal parameters, which will also be environmentally friendly [14,15]. When constructing them, it is necessary to take into account national and international legal acts that impose actions aimed at limiting environmental threats, including the ozone hole [16] and the greenhouse effect [17]. The use of synthetic refrigerants (f-gases) is limited and, therefore, the natural refrigerant use is dedicated to the newly designed devices.…”

The development and construction of a prototype device (food parcel locker), consisting of small cooling and freezing chambers (boxes) ensuring temperature conditions (+5 C or −18 °C), enabling food storage were carried out. The innovative solutions have been introduced in the MainBox device: the appropriate construction of the device (materials, cooling installation), properly functioning systems (control of chillers, security, temperature monitoring), and propane as refrigerant (high energy efficiency, low global warming potential). The risk of explosion has been eliminated by closing of the cooling installation and reducing of propane amount. The refrigeration unit has been adapted to work in external conditions by installing additional elements (pressure switches for compressor protection and for condensing pressure control). In real conditions, the operation of the innovative MainBox food storage device allowing the receipt of food products without having to wait for a supplier was verified. The temperature distribution in all chambers of the cooling and freezing module was investigated using a thermal imaging camera and a temperature monitoring system. The correct operation of MainBox devices was verified during their loading with food products that require specific temperature conditions during storage.
