The present invention relates to a heat pump with an auxiliary heater in which natural water including domestic wastewater is used as a heat source water and an auxiliary heater is inserted in a heat source water path.

熱源水温度を所定の温度まで加熱昇温させている。In a heat pump system that produces hot water using natural water such as river water, lake water, tap water, and sewage as a heat source, the heat pump can handle all natural water temperatures that fluctuate depending on weather conditions. Occasionally there is a risk of freezing due to overcooling. As a countermeasure against this drop in natural water, an auxiliary heating source facility such as a boiler or heater is installed,
The heat source water temperature is heated up to a predetermined temperature.

Is an evaporator, 5, 6 and 7 are refrigerant paths, and 8 is a hot water path. 9
Is a capacity control device, which detects the hot water outlet temperature by the temperature detector 10 and operates, for example, the suction vane opening so that the temperature becomes constant.

状態で導かれ、加熱して温度t1となった後蒸発器４に入
り、これに熱を与えて自体は冷却されて温度t2となり、
放水部としての放水槽18に放流される。In the evaporator 4, heat is received from the heat source water passing through the heat source water paths 11, 12, and 13. That is, in addition to rivers and lakes, natural water including clean water, sewage treatment water, domestic wastewater, etc. is stored in the intake tank 14 as heat source water, and the heat source water supply pump 15
Is led to the auxiliary heater 17 using the auxiliary heating source 16 at a temperature of t 0 , and after heating to a temperature of t 1 , enters the evaporator 4, and heat is applied to this to cool itself. t 2 ,
It is discharged to a water discharge tank 18 as a water discharge part.
19は、蒸発器４の入口の熱源水温度t1を検出する温度検
出器であり、温度t1が所定の温度T1（設計値）となるよ
う流量制御弁20を操作して補助加熱源16からの熱の供給
量を調節するようになっている。Reference numeral 19 denotes a temperature detector that detects the heat source water temperature t 1 at the inlet of the evaporator 4, and operates the flow control valve 20 so that the temperature t 1 becomes a predetermined temperature T 1 (design value), and an auxiliary heating source. It is designed to control the amount of heat supplied from 16.
補助加熱器17は、熱源水温度が、設計条件としている通
常の温度範囲よりも一時的に低下した場合に、熱源水を
加熱して蒸発器４の入口温度を所定のt1に保つためのも
のである。The auxiliary heater 17 serves to heat the heat source water and maintain the inlet temperature of the evaporator 4 at a predetermined t 1 when the heat source water temperature temporarily falls below the normal temperature range which is the design condition. It is a thing.
しかしながら、このような従来の例においては、温水負
荷の状況にかかわらず、自然水温度低下時に、自然水温

負荷が小さく、ヒートポンプが部分負荷運転をする場合
には、ヒートポンプ熱源水出口温度t2が設計出口温度T2
より高いまま放流することになる。すなわち、ヒートポ
ンプの設計上過冷を起こす危険性の無い熱源水設計出口
温度T2になるまで、熱源水から熱を回収できるにもかか
わらず、設計出口温度T2より高い温度t2で熱源水を放流
するという事は、第５図に示す如く、t2−T2の温度差分
の熱量を回収しないまま捨てている事になる。However, in such a conventional example, regardless of the status of the hot water load, when the natural water temperature decreases, the natural water temperature t 0 is heated up to the heat source water design inlet temperature T 1 , so the hot water load is small, When the heat pump operates at partial load, the heat pump heat source water outlet temperature t 2 is the design outlet temperature T 2
It will be discharged at a higher price. In other words, even though heat can be recovered from the heat source water until the heat source water design outlet temperature T 2 that does not cause overcooling due to the heat pump design, the heat source water is heated at a temperature t 2 higher than the design outlet temperature T 2. As shown in FIG. 5, the discharge of heat is to discard the heat quantity of the temperature difference of t 2 −T 2 without recovering it.
また、温水負荷量によっては、自然水温度t0が、設定値
T1以下であっても、温水負荷をまかなうのに必要な熱量

t2は設計出口温度T2を下廻らない事がある。この時に

ず、自然水温度t0が設計入口温度T1より低下したという
条件で、補助加熱源を運転し、自然水t0を設計入口温度
T1まで加熱昇温させる事になり補助加熱源は無駄な運転
をする事になる、という問題点がある。Also, depending on the hot water load, the natural water temperature t 0
Heat pump heat source water outlet temperature after recovering the amount of heat required to cover hot water load from natural water even if it is T 1 or less
t 2 may not fall below the design outlet temperature T 2 . At this time, although the auxiliary heating source equipment can be stopped, the auxiliary heating source is operated under the condition that the natural water temperature t 0 is lower than the design inlet temperature T 1 , and the natural water t 0 is temperature
There is a problem that the auxiliary heating source will be uselessly operated by heating up to T 1 .
また、自然水温度t0が、ヒートポンプに利用し得る所定
の限界温度である設計出口温度T2より第６図に示す如く
低下した場合、その自然水をそのままヒートポンプに供
給することは、温水負荷量の如何に拘らず、（T2−t0）
の温度差に相当する分だけ補助加熱源を過大に、無駄に
運転することになる、という問題点がある。When the natural water temperature t 0 is lower than the design outlet temperature T 2 which is the predetermined limit temperature that can be used for the heat pump as shown in FIG. 6, the natural water is supplied to the heat pump as it is. (T 2 −t 0 ) regardless of quantity
There is a problem that the auxiliary heating source is excessively and wastefully operated by an amount corresponding to the temperature difference.
