Abandonment of gas R22 refrigerant

R-22 PHASE OUT

Programming of the abandonment of gas R22 refrigerant:

From 01/01/2010:

• It is not longer possible to produce and export machines with R-22 (for the European market the ban dates back to 2001)
• It is no longer possible to use the gas R-22 “virgin” for top-up or replacement during maintenance operations.
Replace your old refrigerator R22 and save 25%
A modern chiller with scroll compressor and R410A gas consumes 25% less than an old R22 chiller with reciprocating compressors.

Let’s take an example of how much you can save by replacing an old refrigerator power rating 70,000 kcal/h, assuming an age of 10 years, a natural drop in performance over time of evaporator and condenser, R22 and reciprocating compressors.

Old refrigerator consumption: 172,763 kWh / year
Coefficient of refrigeration old refrigerator consumption: 4,13
Last generation Tempco refrigerator consumption: 128.631 kWh/year
Coefficient of last generation Tempco refrigeration: 5,52
Saving 25%
= 44.132 kWh/year at medium cost of 0,15 Euro/kWh
= 6.619,00 Euro/year
If the same is associated with a free cooling system, the savings can exceed to 80%.

Chiller and Service

On summer season, industrial plants gives problems related to hot ambient temperature.

Last week our service receive a call related to a big plant which don’t perform at usual temperature.

Customer tell us that chiller can’t perform correct temperature during middle day.

Immersed coils or TCOIL plates

On our italian blog we often spoke about the flexibility of TCOIL heat exchangers.

I’m firmly believe in this product and every time we get feedback from market of this feature.

Few weeks ago our good customer operating in steel mill field, contact our technical department because a coil heat exchanger, internal to a waste water single effect evaporator is damaged; the coil has some pitting, but more important is totally scaled and externally clogged.

Energy recovery from air compressor

Air compression central station needs big amount of energy to run.

Compressor generates heat which usually can’t be recovered, but must be dissipated with heat exchanger, evaporative cooler or dry-cooler.

This thermal energy can’t be recovered because the temperature are too low.

There is a fluid inside compressors which operate at higher temperature, it is our target in energy recovery: lubricant oil.

TCOIL tool machinery oil cooling

Another time TCOIL

when we go in workshop to test a TCOIL heat exchanger, our mind goes to solutions and features which this kind of dimple jacket exchanger can achieve.

In this case we can cool down cutting oil for a CNC tool machinery.

The problem is related to the big amount of scale and chippings. A standard heat exchanger will be clogged in minutes.

You can immerge directly TCOIL in the oil tank. The spacing plate by plate is very large allowing ad easy cleaning, without special tools.

A chiller provide cold water for internal circulation inside the TCOIL.

Simple and efficient.
