Fall Birds

leave a comment »

With the change of weather we are seeing a different population of birds in our area. For a while we saw migrating birds passing through. Now we are seeing the ones that stay around for the winter. Here are some photos that I have taken over the last while.

A juvenile male Wood Duck spent a month or so at Kokanee Park while putting on the adult plumage.

I had flushed Wilson’s Snipes at the park a few times, but on this late afternoon where the light was beautiful, this Snipe was quite tolerant of my being near.

This song sparrow put on quite the show for me, stretching and contorting itself. I like these photos of small birds hiding in the weeds.

This Hooded Merganser was seen on the Nelson waterfront.

R-22

leave a comment »

R-22 and any HCFC blends such as MP-39 or HP80 have seen substantial price increases over the last while. This is due to the phasing out of HCFC refrigerants that started in 2010. Each year there are new surcharges, and the last increase this fall put the price above alternatives.

I will be starting to stock the alternative refrigerants in the new year and will be proposing a changeover strategy for your equipment. The best way is a gradual changeover, taking advantage of repairs to  reclaim the HCFC refrigerant and replace it with an alternative. That would minimize the cost and over time all your equipment will be updated.

The new alternatives promise to be much less troublesome than the R-12/R-502 changeovers from a decade ago. They don’t require changing the lubricants and have good performance characteristics.

Our plan is to select a range of alternatives that cover the three pressure characteristics and use them. There are literally dozens on the market right now.

Enjoying the Kootenays

leave a comment »

The Kootenays are a beautiful place to live. It would be a shame to live here an not enjoy what we have.

I carry a camera with me in the truck and take advantage of the opportunities that present themselves to take some photos. I’d like to share some over the next few months.

I was doing a job in Balfour last winter. It was wet and snowy. This woodpecker was drilling into a snag at the back of my customer’s building. I tried to get some pictures, but he would move around behind the snag. After a few unsuccessful shots I went to do the job. After an hour or so we came out and he was still working away. This time he didn’t hide.

Efficiency and Comfort

leave a comment »

A commercial heating and cooling installation must fill opposing goals; comfort, energy efficiency, reliability, quiet.

A recently completed project had all these goals.

It was imperative that the temperature be comfortable, there be adequate ventilation. The work performed in the space is very detailed and technical, at the same time repetitive. Uncomfortable staff results in mistakes and low productivity.

There was a working system consisting of an old atmospheric gas burner furnaces with air conditioning condensing units. There was an opening for fresh air. The duct work was adequate.

We installed two high efficiency furnaces, each serving a floor. The furnaces have variable speed ECM motors, and two stage gas burners. We haven’t run the system in the winter months, but in the spring it worked well. The heating would run on low fire and low fan, gently warming the space. The occupants hardly knew the system was running.

We installed indoor coils above the furnaces tied to heat pump outdoor units. This gives the owner economic choices when it comes to heating. Currently natural gas is inexpensive, so the heat pump operation is limited to warmup on cool mornings. The cooling is 15 SEER. When the system is running in cooling it isn’t drafty or noisy.

We installed mixing dampers on both systems, along with a relief air hood. They can be run in 100% fresh air mode, or modulated to maintain discharge temperature, or minimum ventilation air. There was an existing Delta control board which we use to fine tune the control. We implemented a free cooling algorithm, where a call for cooling first tries to satisfy demand with fresh air. At the current loads in the space, we disable dx cooling at 19c. We have found that the occupants don’t notice slightly warmer temperatures if the air is fresh.

We also implemented a building purge and cool down cycle. The building has a south-west facing wall with large windows. It gets the sun until it sets in the evening. Previously, the building would continue warming up in the evening, and when everyone showed up in the morning, the outside walls and furnishings were warm. It would take a number of hours running dx cooling to bring the temperature down. The cool down cycle starts after midnight and runs the fan with full open dampers to cool the space down to a degree above heating setpoint. There are a number of logic checks to prevent cooling things down and needing to run the heat to make it comfortable.

The results have been satisfactory. A July hot day, the system shut down at 5PM and went on setback. The building warmed up to 29C. After midnight the fans came on, and by 6am the building was at 22C. The low outside was 16C. The mechanical cooling didn’t come on until around 11AM when building came out of the shade of it’s neighbor and started warming up. The current draw for the various components makes 1 hour of dx cooling equivalent to 7 hours of fan at full speed. In the hottest conditions we cut the equivalent of 2 hours of dx runtime, or approximately 20%.

We and the client are quite satisfied.
