Compressor Change in Historic District

Sun, 11 Jul 2010 08:29:14 -0400

Finding an appropriate location for air conditioning equipment in an historical district can be complicated. The condensing unit for this site (the large heat-rejection component), which is typically located outside, is placed inside a below-grade pit. Late last week one of the compressor reed valves broke damaging one of the compressor’s six pistons and its associated cylinder.
The damage was too severe to make a field repair of the compressor so a new one needed to be installed. With the help of riggers the multi-hundred pound compressor was changed out yesterday.
The system is running well and the historic district remains unaffected.

High efficiency propane-fired boilers serve the heating, water heating and pool-spa heating needs of this multi-building residence.

The main distribution manifold and circulators distribute heated water to the various destinations on the property. Main fluid flow is provided by two variable frequency drive (VFD) circulators which vary power use in proportion to the demand - as the ambient air temperature drops, the circulators speed up to move more fluid.
