  • Publication number: 20120018129
    Abstract: It is aimed to simultaneously supply hot water at a required temperature to a high-temperature heating appliance and hot water at a required temperature to a low-temperature heating appliance, the low-temperature heating appliance requiring hot water at a temperature lower than a temperature required by the high-temperature heating appliance, and to enhance efficiency by collecting surplus heat when the temperature of the hot water to be supplied to the low-temperature heating appliance is adjusted. A pipe through which flows the hot water at a high temperature to be supplied to the high-temperature heating appliance is branched into a first supply pipe and a second supply pipe. Heat exchange is effected between the hot water flowing through the first supply pipe and return water which has been supplied to a first appliance.

  • Publication number: 20110315093
    Abstract: When using a plurality of heaters such as heat pump units, capacity is properly distributed according to the required capacity, thereby enabling highly efficient operation of a hot water system. To achieve this, a control apparatus determines the heating capacity of each of the heat pump units in a way that the total heating capacity of the heat pump units reaches the heating capacity required in the hot water system as a whole, and further in a way that the total COP (coefficient of performance) of the heat pump units satisfies predetermined condition. The control apparatus controls each of regulating valves in a way that the heating capacity of each of the heat pump units reaches the above determined heating capacity.

  • Publication number: 20080041097
    Abstract: The present invention aims to provide a refrigerant distribution device which eliminates a need for maintaining a certain length of a straight portion at an inflow tube to a distributor, and for adjusting lengths of capillary tubes to send a refrigerant to each flow path of the refrigerant of a heat exchanger, and which resolves an unevenness of a liquid refrigerant at a bend of the inflow tube due to a centrifugal force. A refrigerant distribution device according to the present invention including an inflow tube, which is connected to a distributor for distributing and providing a refrigerant in a gas-liquid two-phase state to a heat exchanger, wherein an upstream side of the inflow tube is in an approximately horizontal position and a downstream side of the inflow tube is bent to stand approximately at a right angle, includes a bend of the inflow tube, a longitudinal form of which is made of a combination of straight lines and is bent approximately at a right angle.
