Country Hotel

Technical and economic constraints of the project:

In this case the main constraints were the long distances that separated the freezing rooms from the machine room, where the outside units are located, the high temperatures of the area in summer and the need for a low noise level in order not to affect the guests while resting.

Proposed solution:

For this reason, the installer chose Daikin’s ZEAS units. Two ZEAS units were installed, one to provide service to the cold storage rooms and furniture and the other to provide service to the freezing rooms.

Benefits of the proposed solution:

• Low noise level: ZEAS units are 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 hotel guests 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 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, 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 . 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.
• Distance of up to 130 m between the outside and inside units. This made it possible to carry out the installation without malfunctions or performance losses.
