HVAC system of the cafe-bakery "Baker Brothers"

What was done

The Baker Brothers cafe-bakery has a decentralized HVAC system that ensures maximum energy savings both in summer and air conditioning of the retail space and the bakery kitchen, and in the winter on heating і ventilation.

Implemented technical solutions:

1. Air source heat pump (air conditioner) from the Hitachi brand. It can generate up to 20 kW of heat, consuming 4 kW of electricity. Air flows are evenly distributed thanks to efficient indoor units of wall and cassette type.
2. Highly efficient supply and exhaust ventilation systems with modern recuperators that return up to 80 percent of the heat and up to 50 percent of the cold back to the halls. All the heat from the furnaces is utilized in the cold season, heating the supply air for general ventilation. The quietest and most economical fans, noise mufflers, vibration dampers, and noise-suppressing insulation are used.

Stages of work

Energy studies and calculation of the most efficient and cost-effective equipment were carried out.

A conceptual solution for the implementation of HVAC systems was prepared and agreed with the designer and related organizations.

We designed supply and exhaust ventilation systems and split air conditioning and heating systems.

We marked and planned the installation of equipment and utilities, prepared sites and places for equipment mounting, and punched holes for channels and pipes.

At the first stage, air ducts, freon lines, and electrical cables were laid and insulated. A supply and exhaust unit with a kitchen exhaust fan and a supply duct fan, a sealed plate recuperator, a backup electric heater and other elements were installed.

A Roda air handling unit with a polystyrene recuperator and an additional heater was installed. A Hitachi air-to-air heat pump with indoor units was installed, which operates as the main heating and air conditioning system. Automation and dispatching works have been completed.

The equipment was tested and the quality of work was monitored, and the system was adjusted and set up for further operation.
