摘要： Embodiments of the present disclosure include techniques for determining thermodynamic properties of buildings. In one embodiment, a method for determining a building UA-value comprises monitoring indoor and outdoor air temperature during a drift phase over a first time period, and monitoring a temperature control system run time during a second time period over which the temperature control system in the building restores indoor air conditions to an initial state at the beginning of the first time period. Additionally, an amount of heat energy change may be determined during the second time period. Embodiments may determine thermal resistance of the building from data obtained during over the two time periods, for example.

摘要： An electrical interface selectively places a heat pump and a backup temperature control device in alternative electrical communication with a single power feed, thereby simplifying installation and reducing cost. In particular embodiments, a compressor of the heat pump may be in selective electrical communication with the power feed via a normally closed relay. Removal of a control voltage results in opening of the normal open relay, and closing of a normally closed relay to place the backup temperature control device in selective electrical communication with the power feed. For a ground source heat pump, a ground loop pump may also be in selective electrical communication with the power feed (e.g., via a normally closed relay).

摘要： In some embodiments, a method operates a heat pump that uses a ground loop to perform heating or cooling in a site. During the operating of the heat pump over a time period: the method measures a first series of measurements of a ground loop water flow rate by the heat pump; a second series of measurements of a ground loop fluid temperature for the heat pump; and measures a third series of measurements of a local soil or deep earth temperature. The first measurement, the second measurement, and the third measurement are outputted where a ground loop thermal resistance value is calculated for the heat pump based on the first measurement, the second measurement, and the third measurement.

摘要： In order to install a ground loop for a geothermal heating and/or cooling system in ground material, a drilling machine having a drill bit connected to an end of first tubing may be used to create an borehole in the ground material. After the borehole is created, grout may be pumped into the borehole through the first tubing as the first tubing is removed from the borehole. This allows the borehole to be grouted from the bottom towards the top. Thereafter, second tubing may be inserted into the grout in order to create the ground loop. This eliminates the need for a “tremie” pipe to insert the ground loop and pump grout into the borehole, while still allowing for the borehole to be grouted from the bottom towards the top to reduce the likelihood of voids.

摘要： A multi-stacked heat exchanger comprises a first heat exchanger and a second heat exchanger. A first end of the first heat exchanger receives a first fluid in a first conduit flowing in a first direction within a plane. A first end of the second heat exchanger receives the first fluid from the first heat exchanger in a second direction flowing opposite to the first direction within the plane. A flow of a second fluid is communicated through the second heat exchanger and then through the first heat exchanger, in a second direction orthogonal to the first direction. The second fluid is in thermal communication with the first fluid in the second heat exchanger and then in the first heat exchanger. By doubling the flowed first fluid back upon itself, embodiments achieve counterflow between the first fluid and second fluid within a compact space.

摘要： A blower and heat exchanger component of a heat pump includes a physically moveable service panel. The service panel can slide out on a first side or on a second side opposite to the first side, where an existing air duct connects to a third side that is orthogonal to the first and second sides. This sliding service panel configuration allows a same blower/heat exchanger component to adapt the duct being located on either side of the unit (e.g., by installing the component rotated by 180° within the installation space as appropriate). The service panel can slide out on both sides of the component, thereby affording access for service, irrespective of orientation of the component as installed relative to the duct.

摘要： A blower and heat exchanger component of a heat pump, includes physically moveable interface blocks located at the corners. The blocks are relocatable to different corner locations on the unit, to allow a same blower/heat exchanger component to adapt to an existing duct being located on either side (e.g., by installing the component rotated within the installation space as appropriate). Active interface block(s) moveable to different corners afford access to power connection and/or data connections and status display features. Blank blocks occupy the corner locations left vacant by relocation of active blocks to the side of the unit serving as the front for a particular installation. The moveable corner blocks afford access to the unit for power and data connection, and status display, irrespective of orientation as installed relative to an existing ducting layout of a building.

摘要： A heat pump is equipped with a plurality of sensors configured to measure various physical properties, including but not limited to: (gas/liquid) temperature, (gas/liquid) pressure, electrical current, and/or flow rate. A monitoring center is interposed between the heat pump and other elements of a Heating Ventilation and Air Conditioning (HVAC) system, such as a building thermostat and a heat pump control board. The monitoring center receives the outputs from the sensors and communicates them to a user (e.g., via a wired or wireless interface) for inspection. The monitoring center may also process the sensor data to calculate and output desirable performance metrics such as efficiency and/or available capacity. Where the heat pump is part of a ground source heat pump (GSHP) system or a geothermal heat pump system, embodiments may be particularly useful to also receive and/or process additional sensor input(s) from a flow center component.
