【発明の詳細な説明】
本発明はヒートポンプによって給湯を行なう給湯装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water heater that supplies hot water using a heat pump.
典形的な先行技術ではヒートポンプの凝縮器によって昇
温した水を、そのヒートポンプの圧縮機を駆動する内燃
機関の冷却液が通過するもう一つの熱交換器によってさ
らに昇温し、この第２の熱交換器からの水を貯湯タンク
に導びき、前記貯湯タンクと第１の熱交換器および第２
の熱交換器とによって循環閉ループを形成している。In typical prior art, the water heated by the condenser of a heat pump is further heated by another heat exchanger through which the coolant of the internal combustion engine that drives the compressor of the heat pump passes. Water from the heat exchanger is led to a hot water storage tank, and the water is connected to the hot water storage tank, a first heat exchanger, and a second heat exchanger.
A closed circulation loop is formed with the heat exchanger.
このような先行技術では貯湯タンクの温度を制御するた
めに、循環閉ループに介在されている循環ポンプの流量
を制御する必要があり、構成が複雑化する。また循環ポ
ンプの流量を小さくすると第１の熱交換器の伝熱面積を
大きくしなければならず、そのため構成が大形化する。In such prior art, in order to control the temperature of the hot water storage tank, it is necessary to control the flow rate of the circulation pump interposed in the closed circulation loop, making the configuration complicated. Furthermore, if the flow rate of the circulation pump is reduced, the heat transfer area of the first heat exchanger must be increased, which increases the size of the structure.
さらにまた循環ポンプの流量を小さくしたときには循環
水温と凝縮冷媒との間に温度差が生じる結果となり、ヒ
ートポンプの冷媒圧力が上昇する。したがってヒートポ
ンプの圧縮機を駆動する内燃機関の負荷が大となり、内
燃機関が停止してしまう恐れが生じる。あるいは冷媒凝
縮熱を充分温水に伝えることができない。一方流量を制
御しなければ貯湯夕／り水が全体的に上昇するまで所定
の温度が得られず、時間を必要とする。Furthermore, when the flow rate of the circulation pump is reduced, a temperature difference occurs between the circulating water temperature and the condensed refrigerant, and the refrigerant pressure of the heat pump increases. Therefore, the load on the internal combustion engine that drives the compressor of the heat pump increases, and there is a risk that the internal combustion engine will stop. Alternatively, the heat of condensation of the refrigerant cannot be sufficiently transferred to the hot water. On the other hand, if the flow rate is not controlled, the predetermined temperature cannot be obtained until the entire stored hot water rises, which takes time.
本発明の目的は循環ポンプの流量を制御する必要がなく
、構成が簡単でしかも小形化が可能であり、給湯の立上
り時間が早く、さらにまたヒートポンプの駆動力がむや
みに大きくなることを防ぐようにした改良された給湯装
置を提供することである。The purpose of the present invention is to eliminate the need to control the flow rate of the circulation pump, have a simple configuration, allow for miniaturization, have a quick start-up time for hot water supply, and prevent the driving force of the heat pump from increasing unnecessarily. An object of the present invention is to provide an improved water heater.
