A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

According to certain embodiments, a thermostat is configured for use in a climate control system. The thermostat is operable to use two-way communication for communicating operational information between the thermostat and at least one rooftop unit (RTU) within the climate control system. For example, the two-way communication comprises sending first operational information to the RTU and receiving second operational information from the RTU. The operational information comprising one or more climate control commands, setpoints, configuration information, diagnostics, and/or sensor data. The thermostat is further operable to operate the climate control system based on the operational information communicated between the thermostat and the RTU.

A heat exchanger, an axial-flow fan, a bell mouth, a fan motor, and a baffle plate are disposed in a casing of an outdoor unit. The casing includes a front panel provided with an air outlet, and a rear panel provided with an air inlet. The bell mouth and the baffle plate are disposed on an inner surface of the front panel. The bell mouth has a first opening opened toward the heat exchanger, and a second opening opened toward the air outlet. The baffle plate is disposed to incline from a predetermined position on the inner surface of the front panel toward where the bell mouth is disposed.

A heating, ventilation, and air conditioning (HVAC) system includes a network of wireless remote climate sensors to develop a complete heat map of an enclosed space. The remote climate sensor is configured to collect temperature and humidity data on a zone of the enclosed space. The HVAC system uses a network of these sensors to obtain data points across the enclosed space. The resulting heat map is used by the HVAC system to determine where to direct air in the enclosed space. By comparing the temperature and humidity at a specific remote climate sensor with the user's desired temperature and humidity, the HVAC system can decide whether to increase or decrease the air flow through a variable damper that is located near the remote climate sensor. By conducting this analysis throughout the enclosed space and making incremental adjustments to the air flow in hot and cold spots in the enclosed space, the disclosed HVAC system provides even comfort to the user along with reduced energy consumption.

A cooling assembly includes a plurality of dry coolers. Each dry cooler has an air intake, an air outtake, a heat exchanger panel for exchanging heat with air pulled into the dry cooler, and a fan rotating about a fan rotation axis for pulling air into the dry cooler and rejecting heated air out of the dry cooler. The heat exchanger panel includes a tubing arrangement for circulating fluid therein. The dry coolers are arranged in a plurality of dry cooler stacks. Each dry cooler stack includes a first dry cooler and a second dry cooler disposed above the first dry cooler. The dry cooler stacks are positioned such that the dry coolers of each dry cooler stack reject heated air into a common heat rejection zone. Each dry cooler is oriented such that the fan rotation axis of the dry cooler is substantially transversal to a vertical axis.

A heat exchanger assembly has a frame including first and second legs laterally spaced apart, a lower transversal member extending laterally and interconnecting the legs, first and second upstanding members laterally spaced apart and extending upwardly from the lower transversal member, an upper transversal member extending laterally and disposed above the lower transversal member and connected to the first and second upstanding members, and first and second upper retaining members laterally spaced apart and being connected to the upper transversal member and extending transversally to the upper transversal member. First and second heat exchanger panels are connected to the first and second upper retaining members. The heat exchanger panels are disposed in a V-configuration such that a distance between upper ends thereof is greater than a distance between lower ends thereof. A fan has a fan rotation axis extending generally parallel to the first and second upstanding members.
