Convenience store with Daikin refrigeration installation

There is an increasing number of supermarkets opening convenience stores in city centres. In this case study we present the solution that Daikin proposed to the store owner to address the challenges faced when opening a store on premises located underneath a dwelling in the city centre in record time

Technical and economic constraints of the project:

In city centres we have technical constraints such as reduced space, need for low noise levels and other economic constraints, such as long opening hours and high cost of electricity and refrigerant gases.

Proposed solution:

In this case the solution proposed by Daikin’s technical team was the Conveni-Pack system. This system is able to provide all the temperature levels required in a convenience store with a single outside unit. Cold in medium and low temperatures for the preservation of fresh and frozen food products and also air conditioning of sales room.

Benefits of the proposed solution:

  • Reduced space: The choice of the Conveni-Pack system saw a reduction in the space occupied in the machine room of more than 50% with respect to traditional units. In this manner, the store owner can dedicate more space to the storage of products for sale.
  • Low noise level: The Conveni-Pack system is designed with the same noise level reduction criteria as Daikin’s climate control units, due to which its maximum noise level at full load is only 42 dB(A). This means that neighbours are not disturbed thanks to reduced noise levels.
  • Energy savings: The reduction in electricity consumption is achieved by adjusting compressor inverter speed, so that it only consumes the electricity strictly required to produce the required amount of coldness. Additionally, the Conveni-Pack system recovers the heat of the cold compressors to heat the store free of charge. Since these types of premises have extended opening hours, reduction in electricity consumption is very important, due to the fact that prices in kWh  tend to rise and cost restraint is essential to ensure the owner’s monthly profit margin.
  • Low coolant load Since 2005, in Spain there has been an environmental tax on refrigerants which have the highest direct impact on global warming . The Conveni-Pack system uses an environmentally-friendly coolant, R-410 A, which has a low environmental tax. Additionally, coolant R-410 A has a greater cooling potential than traditional refrigerants, for this reason, in order to produce the same power, it only requires half the number of kgs of refrigerant Less kgs at a lower environmental cost reduces maintenance costs by up to 70% with respect to traditional systems.
