  • Patent number: 11273687
    Abstract: A climate control circuit for a transport climate control system is provided. The circuit includes a compressor, a plurality of evaporators, a suction flow control device, and a controller. The suction flow control device is downstream of the plurality of evaporators and directs the working fluid from each of the evaporators to one of a main suction port and an auxiliary port of the compressor. The controller determines whether each of the evaporators is operating in a fresh temperature range or in a frozen temperature range. For each of the evaporators operating in the fresh temperature range, the controller instructs the suction flow control device to direct the working fluid from the corresponding evaporator to the auxiliary suction port. For each of the plurality of evaporators operating in the frozen temperature range, the controller instructs the suction flow control device to direct the working fluid to the main suction port.

  • Patent number: 11150001
    Abstract: A cooling system is designed to generally allow for one or more compressors to be bypassed when ambient temperatures are low. The system includes a bypass line and valve that opens when ambient temperatures are low and/or when the pressure of the refrigerant in the system is low. In this manner, the refrigerant can flow through the bypass line instead of through one or more compressors. These compressors may then be shut off. To supply any needed pressure to cycle the refrigerant, the system may include a pump that turns on when the bypass line is open. When ambient temperatures are extremely low, thermosiphon may be used to cycle the refrigerant.

    Abstract: A refrigeration cycle device has a compressor, a radiator, a decompressor, an evaporator, a heat medium cooling evaporator, a cooling target device, a detector, and a controller. The heat medium cooling evaporator cools a cooling heat medium by performing a heat exchange between the refrigerant decompressed in the decompressor and the cooling heat medium. The cooling heat medium cools the cooling target device. The detector detects a subcooling state of the cooling target device having a temperature lower than or equal to a reference temperature. Upon the detection of the subcooling state in the cooling target device by the detector, the controller increases the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger as compared to the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger when the detector does not detect the subcooling state.

    Abstract: Systems and methods for cooling computing devices in a data center and measuring airflow are disclosed. The computing devices have cooling fans that can have their fan speed set by management instructions. The devices are mounted in racks between cold aisles and hot aisles and are connected via network switches. The computing devices are oriented so that their cooling fans operate to exhaust waste heat to one side of the rack. Measurement instructions are sent to selected computing devices to cause them to go into a lower power state that reduces or stops computational work and reduces electrical power to the cooling fan so that the fan does not spin based on the electromotive force and can instead spin in an opposite direction based on ambient airflow caused by the difference in air pressure from the hot aisle to the cold aisle.

  • Patent number: 10712021
    Abstract: An underfloor heating (UFH) system limits the floor temperature of an environmental entity (for example, a room) by pulsing (pulse modulating) the flow rate through a hydronic emitter (circuit) heating the environmental entity. Once the heated water fills the circuit during time interval Ton, the flow is stopped for a fixed time Toff before allowing the cycle to repeat until a target temperature is reached. The ratio of flow/no flow (Ton/Toff) may be a proportional lower floor temperature compared to a traditional circuit supporting a constant water flow. The UFH system may heat a plurality of rooms, each having different floor temperature limitations. The floor temperatures may be limited differently by pulsing the hydronic emitters (circuits) rooms differently.

  • Patent number: 10696134
    Abstract: Systems and methods can determine whether an air conditioning (AC) system of the vehicle is being operated under a maximum cooling condition. Responsive to determining that the AC system is being operated under the maximum cooling condition, it can be determined whether vehicle fluid temperatures meet associated predetermined thresholds. If none of the vehicle fluid temperatures meet the associated predetermined thresholds, a heater core valve can be switched to a closed position to reduce a flow rate of the coolant through a heater core. If one or more of the vehicle fluid temperatures meet the associated predetermined thresholds, the heater core valve can be switched to an open position to increase the flow rate of the coolant through the heater core. Such systems can force coolant to flow through the heater core to reduce vehicle fluid temperatures even when the AC system is being operated under the maximum cooling condition.

  • Patent number: 10451351
    Abstract: In one embodiment, a cooling system may include a thermosyphon cooler that cools a cooling fluid through dry cooling and a cooling tower that cools a cooling fluid through evaporative cooling. The thermosyphon cooler may use natural convection to circulate a refrigerant between a shell and tube evaporator and an air cooled condenser. The thermosyphon cooler may be located in the cooling system upstream of, and in series with, the cooling tower, and may be operated when the thermosyphon cooler is more economically and/or resource efficient to operate than the cooling tower. According to certain embodiments, factors, such as the ambient temperature, the cost of electricity, and the cost of water, among others, may be used to determine whether to operate the thermosyphon cooler, the cooling tower, or both.

  • Patent number: 9752815
    Abstract: A heat source-side heat exchanger fan blowing air to a heat source-side heat exchanger performing heat exchange with refrigerant compressed in a compressor is controlled. A current detected temperature at a current time is converted to obtain a current converted high pressure value at the current time. The current converted high pressure is a pressure of refrigerant inside a high pressure-side pipe of the compressor. The current detected temperature is a temperature detected by a temperature detector attached to the heat source-side heat exchanger. A past detected temperature is converted to obtain a past converted high pressure value at the past time. A speed of the heat source-side heat exchanger fan is determined using a corrected converted high pressure value. The corrected converted high pressure value is obtained by correcting the current converted high pressure value based on the past converted high pressure value.
