Why Do I Need a MiniSplit Ductless Heat Pump or Air Conditioner?
There are many people who can actually save some money by installing a minisplit ductless air conditioner or heat pump over installing the conventional ducted split system air conditioner or heat pump. A few of the possible areas where some can use a minisplit ductless heat pump or air conditioner are rooms over the garage where additional heating and cooling is necessary simply because rooms over garages suffer because garages in most homes are not as insulated as is other parts of the home. This usually creates problems with many of the newer homes because I have seen builders who need a lesson in load calculation and properly sizing the air conditioning or heat pump systems for the conditions. I am sure many people will agree especially people who own homes where there is a room over the garage. How many of those people have supplemental heating and cooling by the way of a window unit or portable heater? Many people I would from my observations over the years. Now these people can benefit from the easy installation including lower installation costs of the minisplit ductless heat pump or air conditioner. Other places where minisplit ductless units can be considered for installation are additions to homes and basements where minisplit ductless units are great for dehumidification.
This Trane HVAC chiller serves four different apartments. Chilled water systems offer a great way for multi-zone air conditioning. From small apartment buildings to large commercial buildings chilled water systems can serve multi-zone air conditioning systems. From one air conditioning zone to hundred the only limitation is the size of the chiller. If the air conditioning zoning system (the load) is matched up with the right sized chiller (in tons) the system will serve all air conditioning zones and keep all the occupants comfortably cool. Chilled water systems can also be integrated with the boiler system so that the same system can be used for heating and cooling. A good control system will add efficiency and more comfort to the system. Continue reading “Trane Chilled Water Systems – Multi-Zone Air Conditioning Systems” »
The average compressor in many residential air conditioner or heat pump condensing units are hermetically sealed compressors with the only visible working parts on the compressor are the electrical connections and the copper discharge and suction lines. This makes it difficult to repair any compressor once a diagnosis is made to the air conditioner or heat compressor. Troubleshooting air conditioning and heat pump compressors is not difficult once you understand the basics of the compressor. It doesn’t matter what kind of residential air conditioner or heat pump compressor you are working on as long as it is single phase for use in a residential heat pump or air conditioner. This article will cover the basics of troubleshooting a compressor when the circuit breaker trips continuously.
When you look at buying a new HVAC system it will surely arise when the HVAC salesman or HVAC contractor who comes to give you an estimate will show an HVAC system that has a variable speed motor or the GE ECM (Electronically Commutated Motor) installed in it. These are systems that have a higher efficiency rating than the HVAC equipment that has the typical electric blower or condenser fan motor. The ECM (Electronically Commutated Motor) uses less energy than the standard PSC motor that is commonly used in air handlers and condensers to mover air. The ECM motor also offers more control which has good benefits in HVAC applications. Continue reading “Variable Speed GE ECM Condenser & Blower Motors” »
