20130037253 | METHOD AND APPARATUS FOR REGULATING A COOLING DEVICE FITTED TO A SWITCHGEAR CABINET - The invention relates to a method for regulating a cooling device fitted in or to a switchgear cabinet, by means of a regulating device, wherein the temperature of the switchgear cabinet interior air is detected and an interior fan assigned thereto for generating an interior air flow through an evaporator and providing cooling air is switched on if the detected temperature of the switchgear cabinet interior air exceeds an upper setpoint temperature, and is switched off if the detected temperature falls below a lower setpoint temperature, and the invention relates to an apparatus for carrying out the method. A reduced energy consumption and an increased service life with reliable operation are achieved by virtue of the fact that after the interior fan has been switched off owing to the lower setpoint temperature being undershot, a timekeeping is started and the interior fan is switched on after a predetermined first time duration for a predetermined second time duration and is then switched off again if the detected temperature still falls below the upper setpoint temperature, as long as the second time duration proceeds, that the intermittent time-controlled mode of operation of the interior fan is cyclically repeated until the upper setpoint temperature is exceeded, after which the interior fan is operated in continuous operation, and that the timekeeping and the intermittent time-controlled mode of operation of the interior fan are started anew if the lower setpoint temperature is undershot. | 02-14-2013 |
20130160987 | COOLING - The present invention relates to improvements in or relating to cooling, in particular for cooling beverages in containers such as cans or bottles. We describe a cooling apparatus having a cavity for receipt of a product to be cooled; rotation means to rotate a product received in the cavity and cooling liquid supply means to provide a cooling liquid to the cavity. The rotation means is adapted to rotate the product at a rotational speed of 90 revolutions per minute or more and is also adapted to provide a pulsed or non-continuous rotation for a predetermined period. | 06-27-2013 |
20130277037 | Temperature-Independent Control Of A Thermostatically-Controllable Cooling And/Or Heating Appliance - A method of at least in part temperature-independently controlling a thermostatically-controllable cooling and/or heating appliance is provided. The method comprises the step of periodically at least in part temperature-independently deactivating and reactivating a thermostatically-controllable cooling and/or heating element of the said appliance whilst the cooling and/or heating element of the cooling and/or heating appliance is ordinarily energised to heat and/or cool during an energisation period of a or each standard duty cycle. A deactivation period of the cooling and/or heating element is at least in part controlled by a timer element. The deactivation period is also automatically adjustable based on a deactivation-period profile associated with the timer element, and the deactivation period is further automatically adjustable when the cooling and/or heating element is thermostatically or manually deactivated during the energisation period of the or each said standard duty cycle. | 10-24-2013 |
20140014312 | ENERGY-EFFICIENT HOT WATER SUPPLY APPARATUS - An energy-efficient hot water supply apparatus comprises a control assembly and a controller. The control assembly is disposed between an external energy supply source and a heating apparatus, so as to control turning on/off of energy supply of the energy supply source to the heating apparatus. At least one activation switch is disposed on the controller. The activation switch can operate the control assembly to cut off the entry of the energy of the energy supply source to the heating apparatus and keeps a fixed off duration. | 01-16-2014 |
20140166261 | AIR CONDITIONING SYSTEM USING DEEP SEAWATER - An air conditioning system using deep seawater, includes: a pump device pumping the deep seawater; a seawater-coolant heat exchanger performing heat exchange between a cold energy in the deep seawater and a coolant; an air conditioning heat exchanger performing heat exchange with the coolant cooled by the cold energy to release the cold energy in a target facility for cooling; a coolant circulating system circulating the coolant between the seawater-coolant heat exchanger and the air conditioning heat exchanger; and a controller driving the pump at timing when a variation is anticipated in the predicted heat loads based on the predicted heat load of the facility predicted from a prediction value of an operation status of the facility and a prediction value of a weather status at the place of the facilitate and a time lag due to a length of the pipe in the coolant circulating system. | 06-19-2014 |
20140332195 | CHILLER CONTROL - A method includes predicting, using a predicted flow of heat into an area, a quantity of energy used by a chiller to maintain a temperature of the area at a desired temperature during each of a first plurality of time periods of a chilling cycle. A set point of the chiller is automatically during the chilling cycle using the predicted quantity of energy. | 11-13-2014 |
20160096414 | REFRIGERANT CIRCULATION SYSTEM - In order to shift a rotation angle of a rotor to a region of a normal mode (for example, a region c) from a region of a heater cut mode (for example, a region e), the rotation angle needs to pass through a region where a flow rate of a refrigerant which is caused to flow through all branch channels becomes zero (a region d). When the refrigerant has a high temperature, there is a possibility of the refrigerant being not cooled, and boiling. Therefore, when a request to switch a normal mode and a heater cut mode is issued, permission/non-permission of switch of the mode is determined by comparison of a temperature of the refrigerant detected by the temperature sensor | 04-07-2016 |

20100263853 | Periodic Flow Heat Exchanger - A heat exchanger includes a first regenerator core and a second regenerator core and a four-way valve coupled to a cold section of the first regenerator core and to a cold section of the second regenerator core. The four-way valve directs input air to the first regenerator core or to the second regenerator core. A high-temperature passive check valve is coupled to a hot section of the first regenerator core and to a hot section of the second regenerator core. The high-temperature passive check valve comprises an inlet header coupled to the hot section of the first regenerator core or the second regenerator core, a valve poppet coupled to a valve stem and a valve seat located on a surface parallel to a surface of the valve poppet. Air entering the inlet header moves the valve poppet away from the valve seat, creating an opening through which air passes. | 10-21-2010 |
20150068722 | Circulating Cooling System and Method for Controlling Circulating Cooling System - A circulating cooling system and a method for controlling the circulating cooling system are disclosed in this disclosure. Wherein, the circulating cooling system is divided into three parts: an internal cooling circulation device, a plate heat exchanger and an external cooling circulation device, wherein the internal cooling circulation device is adapted to perform circulating cooling on a heat-generating device; the plate heat exchanger is adapted to perform heat exchange between external cooling water in the external cooling circulation device and the internal cooling water in the internal cooling circulation device; the external cooling circulation device is adapted to cool the external cooling water. Also, the external cooling primary circulation pump, the cold accumulation water pool, the water-air plate-wing heat exchanger, the cold accumulation air cooler, the first valve and the second valve may be controlled, respectively. Thus, water consumption and power consumption may be effectively reduced while cooling the heat-generating device. | 03-12-2015 |
