Urban butcher's

The establishment specialises in the sale of quality meat in the province of Gerona. In this case study, the establishment is located in the city centre, with the constraints which said location represents.

Technical and economic constraints of the project:

In this case, the main constraint was the proximity of neighbours. The lack of space inside the establishment made it necessary to install the cooling and climate control units to the exterior of the establishment, specifically on the roof. Due to which the low noise level of the units was a key factor.

Proposed solution:

For this reason, the installer chose Daikin’s ZEAS units. A ZEAS unit was installed to provide service to the meat display windows and to the cold storage rooms. A sky air-type unit, also installed on the roof of the establishment, was used to air condition the sales room.

Benefits of the proposed solution:

Low noise level: ZEAS condensing units are designed with the same noise level reduction criteria as Daikin’s climate control units, due to which their maximum noise level at full load is only 42 dB(A). This means that neighbours are not disturbed thanks to reduced noise levels.


  • Reduced space: The choice of the ZEAS system represented a reduction in the space taken up in the machine room of more than 35% with respect to traditional units. As a result, the store owner can dedicate more space to the preparation room or food preservation rooms.
  • Energy savings: The reduction in electricity consumption is achieved by adjusting compressor inverter speed, so that it only consumes the electricity required to produce the required amount of coldness. Since these types of premises have extended opening hours, a reduction in electricity consumption is very important, due to the fact that kWh prices tend to rise and cost restraint is essential to increase the owner’s profit margin.
  • Low coolant load Since 2005, in Spain there has been an environmental tax on coolants which have the highest direct impact on global warming . ZEAS condensing units use 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 due to leaks by up to 70% with respect to traditional systems.
