High efficency heating and ventilation of the canning company “Palirria” Nova Zagora

One of the projects where a good cooperation has been reached between the customer who knows what he wants, designer and performer who can do it, is a new canning enterprise “Palirriya”.

The factory is a new investment of “Palirria Bulgaria” and as a result of experience gained they were able to prepare a precise specification. One of their requirements was the recuperation (recovery) of energy from the exhausted air.

The technological process is connected with intensive discharge of heat and moisture from certain work stations. Local suction helps the air exchange to be minimized, but still the ventilated air from the general circulation ventilation is more than 24 000 m³ / h.

Analysis of the possibilities for energy recovery through recuperation in the ventilation and air conditioning systems.

It seems the discussion for the necessity of energy recovery systems is over not only in Western and Northern European countries, but also in Bulgaria. For the people who made serious effort for convincing and proposing legislative changes in the last 20 years, it is a real success. Today it is rare to see a ventilation or air conditioning project without energy recovery (recuperation or regeneration).

The economic pressure (rise of energy prices) surpassed the legal regulations. Designers and investors reacted more adequately than the legislators.

The next important step is the choice of the right energy recovery system. The right choice means a cost-effective choice that doesn’t compromise the microclimate.
