Heat pumps Warranty can be operated to much lower temperatures allowing for full utilization of their efficiency while optimizing system performance. A duct sensor constantly monitors outlet air temperature and modulates the precise amount of stored off-peak heat needed to eliminate uncomfortable discharge air temperatures typically associated with heat pump systems during cool outdoor temperatures. The air handler also directs the heat lost statically through the furnace’s outer panels into the ductwork for delivery to the living space (automatic static heat recovery). The internal controls of the Comfort Plus Hydronic furnace automatically regulate the operation of the air handler. OPERATION: A heat call from the room thermostat will energize the pump to circulate a water/glycol solution through the Comfort Plus Hydronic’s heat exchanger where it is heated to the appropriate temperature. This heated water solution is then circulated through the air handler’s water coil.

  • Air Leakage of Furnaces and Air Handlers
    Air Leakage of Furnaces and Air Handlers Iain S. Walker, Darryl Dickerhoff, and Woody Delp, Lawrence Berkeley National Laboratory Mike Lubliner, Washington State University ABSTRACT In recent years, great strides have been made in reducing air leakage in residential and to a lesser extent small commercial forced air duct systems. Several authorities have introduced low leakage limits for thermal distribution systems; for example, the State of California Energy Code for Buildings gives credit for systems that leak less than 6% of the total air flow at 25 Pa. Practitioners have found that a significant barrier to meeting specifications like this is the air leakage of the furnace or air handler itself. Anecdotal evidence exists for the magnitude of the air leakage of furnaces and air handlers. The states of California and Florida include air leakage limits for the furnaces in their State Building Energy Codes. However, there is currently no standard test method for measuring this air leakage that could be used for uniform and reliable ratings. This paper presents the results of laboratory measurements air leakage testing of furnaces and air handlers. The results indicate that average air leakage is significant - confirming existing anecdotal evidence. Also, the air leakage has a wide range from furnace to furnace indicating that low levels of air leakage are already attainable with existing equipment and the rating for air leakage will be able to distinguish between good and poorly performing equipment. This paper will also discuss the development of a standard test procedure (ASHRAE Standard 193 "Method of Test for Determining the Airtightness of HVAC Equipment") that will be used by Federal, State and Local code authorities and efficiency programs as well as appliance standards, utility programs and a range of other applications.

  • Humidity Control: Supplemental Technote Dehumidification in Hot-Humid Climates
    TechNote Humidity Control: Supplemental Dehumidification in Hot-Humid Climates Managing indoor humidity in hot-humid climates is more important than ever for new, energy efficient homes equipped with whole- house mechanical ventilation. In these homes, air conditioning systems are less effective at removing humidity from the air, particularly during part-load conditions or shoulder seasons when cooling is normally not required (e.g., November-March). Yet, more humid outdoor air is brought into the house as a result of increased ventilation rates. Although tighter construction practices help reduce air infiltration, the net effect is an increased supply of humid outdoor air into the house. These conditions tend to lead to increasing the risk for musty odors, mold-mildew, and comfort complaints (e.g., cold and clammy feeling). In addition, high indoor humidity can result in increased energy use because occupants tend to compensate by using a lower thermostat setting in the summer [1]. This TechNote provides an overview of strategies for improving humidity control in hot-humid climates (applicable as well in other humid climates). The focus is on supplemental dehumidification methods using commercially available equipment. Supplemental dehumidification is not intended to be used as a means for compensating for over-sized HVAC equipment or excessive building leakage rates. A strategy to improve humidity control can include combinations of the following: Air Conditioning. Air conditioning systems perform two functions: cooling (to reduce the temperature of the air) and dehumidification (to remove moisture from the air). Air conditioning controls are commonly designed to control temperature, not humidity. Two- or multi-stage systems may improve dehumidification depending on equipment and air flow selections [2].
