Abstract: In order to reduce the effect on a compressor caused by foaming in an oil tank, a control unit for controlling an oil pump starts the oil pump before a compressor is started (SA1), starts the compressor (SA4) when an oil supply differential pressure P satisfies a compressor startup condition during a reference time Tas from the starting of the oil pump (“Yes” in SA3), and extends the operation of the oil pump for a prescribed time without starting the compressor (Step SA5) when the compressor startup condition is not satisfied (“No” in SA3).

Abstract: An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

Abstract: An aspect of the embodiments provides a compensation for the temperature rise effect on the printed circuit board (PCB) of an electronic thermostat to obtain better precision and performance. Once the measurements from the temperature sensors have stabilized, the compensated ambient temperature may be used by an associated system (for example, a Heating, Ventilation, and Air Conditioning (HVAC) system).

Abstract: A cooling system is designed to operate in two different modes. Generally, in the first mode, when parallel compression is needed, certain valves are controlled to direct gaseous refrigerant from a tank to a compressor in the system and to direct refrigerant from low side heat exchangers towards other compressors. In this manner, a compressor in the system is transitioned to be generally a parallel compressor. In the second mode, when parallel compression is not needed, the valves are controlled to return the refrigerant flow back to normal.

Abstract: A refrigerant leak detection and mitigation system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a refrigerant gas sensor (RGS), sensor signal conditioner (SSC), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The RGS detects ambient refrigerant gas (ARG) and indicates this as a refrigerant sensor voltage (RSV) to the SSC. The DCP and SSC form a closed control loop (CCL) in which the SSC electrical characteristics are adjusted by the DCP such that the RSV is continuously and dynamically recalibrated to account for background refrigerant gas levels, changes in ambient air conditions, RGS manufacturing tolerances, and other field-specific operational conditions that impact the RGS detection capabilities. The DCP is configured to log alarms to the ASI if a RGS refrigerant leak is detected and optionally shutdown one or more HVAC system components such as a specific air handler leaking refrigerant.

Abstract: The invention relates to a heat exchanger comprising a first free space (7) for a first fluid (3), a thermally conductive wall (11) which, at least locally, delimits said first free space (7), in such a way that an exchange of heat can occur between the first fluid and the thermally conductive wall (11) which is hollow and encloses a material (13) for storing thermal energy by accumulation of latent heat, by heat exchange with at least the first fluid. The first free space (7) is divided into at least two separated channels (7a, 7b) in which two streams of the first fluid (3) can circulate at the same time but separately, the thermally conductive wall (11) which encloses the thermal energy storage material (13) being interposed between the two channels (7a, 7b).

Abstract: An air-conditioning system includes a heat source unit, an air conditioner connected via piping to the heat source unit and configured to perform heat exchange between water supplied by the heat source unit and indoor air, a water circulation device for circulating the water between the heat source unit and the air conditioner, and an air-conditioning control device. The air-conditioning control device controls the heat source unit to lower temperature of the water flowing into the air conditioner, in accordance with an increase in an indoor humidity, and controls the water circulation device to lower temperature of the water flowing from the air conditioner back to the heat source unit, in accordance with an increase in an indoor temperature.

Abstract: In a method for operating a compressor (22) having an inlet (26) and an outlet (28), the method includes: running the compressor to compress a fluid; shutting down (422) the compressor; determining (420) a condition-dependent threshold restart pressure difference (threshold) across the compressor; relieving the pressure difference to reach the threshold; and, after the threshold is reached, restarting (434) the compressor.

Abstract: When a humidity condition, including a humidity detected by a temperature and humidity sensor and a humidification load sensing unit falling below a threshold value, is met, an outside air conditioner supplies the heated and humidified air into the room. When the humidity condition is met during the indoor heating operation, the indoor heating operation is stopped or weakened. When the humidity condition is met, only the outside air conditioner is subjected to a heating and humidifying operation. Since the indoor air is not heated by the inside air conditioner more than necessary, when a heating load is low and a humidification load is present, a “conflicting state” can be prevented in which the inside air conditioner is subjected to a cooling and dehumidifying operation and the outside air conditioner is subjected to the heating and humidifying operation.
