As shown in Figures 2 and 3, the cogeneration of present embodiment equipment 1 cabinet 2 that possesses as casing.The inside of this cabinet 2 is split into up and down two-part, and downside consists of engine compartment 3 and equipment accommodation chamber 5, and upside consists of radiator chamber 7, suction chamber 8 and exhaust chamber 9.
The generator 11 that in above-mentioned engine compartment 3, disposes motor 10, driven by this motor 10 and the fuel tank 12 of storing lubricant oil etc.
The said equipment accommodation chamber 5 is configured in the side (right side shown in Figure 2) of engine compartment 3.In equipment accommodation chamber 5, dispose control box 17 and the transducer 14 of the control gear 16 that possesses control engine drivetrain equipment etc.
Above-mentioned radiator chamber 7 is configured in the top of equipment accommodation chamber 5, at this radiator chamber 7 equipped with radiator 18 and cooling water tank 20.Above radiator chamber 7, dispose the radiator fan 19 that drives the heat transmission of control by above-mentioned control gear 16.
In suction chamber 8, dispose respectively air cleaner 22 and intake silencer 23.Dispose exhaust silencer 24 at exhaust chamber 9.
Then, with reference to Fig. 1 the engine cooling water loop is described.This engine cooling water loop 30 possesses the cooling waterpump 32 that becomes be used to the driving source that makes the engine cooling water circulation.Cooling water path (water jacket), exhaust-heat exchanger 33, the thermostat 35 of ejection side (cooling waterpump blowing unit 32a) in the downstream side is connected with motor 10 in turn from this cooling waterpump 32.
Motor 10 is the stationary gas motors take city combustion gas etc. as fuel, and its vent systems possesses above-mentioned exhaust-heat exchanger 33 and above-mentioned exhaust silencer 24.And the engine cooling water by motor 10 is admitted to exhaust-heat exchanger 33, after exhaust-heat exchanger 33 obtains the heat of waste gas, flows into thermostats 35 via path 31.
Water/water heat source exchanger 37 will offer the outside from the heat that engine cooling water obtains, and for example supply with heat to the water that flows through 2 water sides 38 that hot-water supply uses.Be respectively arranged with the temperature transducer 43,44 of the temperature that detects engine cooling water in the upstream and downstream position of water/water heat source exchanger 37.
Engine cooling current direction radiator 18 and the electric T-shaped valve 34 of water/water heat source exchanger 37 have been passed through.That is, electric T-shaped valve 34 is made of the mortor operated valve by above-mentioned control gear 16 controls, has these three ports of the first cooling water inlet 34a and the second cooling water inlet 34b and coolant outlet 34c.
And the first cooling water inlet 34a is connected with the downstream of extending the heat radiation recover path downstream 39 that arranges from water/water heat source exchanger 37.In addition, the second cooling water inlet 34b is connected with the downstream of extending the radiator path downstream 40 that arranges from radiator 18.So, dispose three-way valve 34 in the interflow section of heat radiation recover path downstream 39 and radiator path downstream 40.In addition, heat radiation recover path downstream 39 is connected with radiator 18 via path 42.
In addition, coolant outlet 34c is connected with above-mentioned low temperature side path 35a via cooling water tube 41.
Electric T-shaped valve 34 can change the aperture ratio (adjustment aperture) between the first cooling water inlet 34a and the second cooling water inlet 34b, determines the aperture ratio according to the heat exchange amount of water/water heat source exchanger 37.Particularly, in the many situations of the heat exchange amount of water/water heat source exchanger 37, namely, in the heat dissipating capacity of the engine cooling water situation how, aperture to the first cooling water inlet 34a becomes large, in the few situation of the heat exchange amount of water/water heat source exchanger 37, namely, in the few situation of the heat dissipating capacity of engine cooling water, the aperture of the second cooling water inlet 34b is become large.
Water tank (water storage tank) 20a and these two-part of metal another water tank (air-water separation case) 20b that above-mentioned cooling water tank 20 is made by synthetic resin consist of.Be connected with the breathing pipe 48 that always can be communicated with atmosphere at a water tank 20a.A water tank cooling water bottom surface that is provided with breathing pipe 48 is configured in another water tank bottom surface sustained height or than higher height, and a water tank 20a is communicated with by connecting tube 46 with another water tank 20b air section of retaining separately.And the water seal section of two water tank 20a, 20b (storing the part of engine cooling water) was communicated with via the connecting tube 47 that extends each water tank bottom.
The bottom of another water tank 20b was connected with the top 18a of radiator 18 via connecting tube 45.In addition, be connected with connecting tube 49 in the bottom of another water tank 20b with in exhaust-heat exchanger 33 and between the pipe arrangement that flows through of engine cooling water (diagram is omitted).Radiator 18 or exhaust-heat exchanger 33 are configured in ratio engine 10 higher heights, and this is to retain because air easily occurs in the chilled(cooling) water return (CWR).Like this, by leading to the degassed loop of air-water separation water tank in the setting of the position of the hidden danger that has air to retain, when the suction of the cooling waterpump 32 that carries out air-water separation, only engine cooling water returns.
In addition, flow to too much connecting tube 45 and 49 for preventing engine cooling water, and for the pressure with the suction side of cooling waterpump 32 is adjusted into any pressure below the hydraulic head pressure, and dispose restriction 60 and 61.
But, need to be with the pressure of cooling waterpump inhalator 32b in the extreme situation about descending, increase restriction 60,61 diameter, perhaps, from connecting tube 45,49 removing restriction, by at communication path 50 restriction 51 being set, the loop internal pressure can be adjusted into more low pressure.
The cogenerator 1 of present embodiment is comprised of above structure, next, the do action in the chilled(cooling) water return (CWR) is described.
When making cooling waterpump 32 operation, be supplied to motor 10 from the engine cooling water of cooling waterpump 32 ejections, by during in the motor 10, by cooling cylinder etc. everywhere and temperature rises, further by exhaust-heat exchanger 33 arrival thermostats 35.At thermostat 35, when the temperature of the not enough regulation of cooling water temperature, make engine cooling water coolant return pump 32.
And when engine cooling water reaches set point of temperature when above, thermostat 35 makes engine cooling current direction water/water heat source exchanger 37.At this, if the requirement of hot-water supply is arranged, then in water/water heat source exchanger 37, the water that 2 water sides 38 that the heating of the heat of engine cooling water is used at hot-water supply flow, and be fetched to the outside.And, according to the flow that flows to radiator 18 of the adjustment of the heat exchange amount in water/water heat source exchanger 37 engine cooling water.In the situation that heat exchange amount is many, the opening of opening ratio the second cooling water inlet 34b of the first cooling water inlet 34a of electric T-shaped valve 34 is large, the heat radiation recover path downstream 39 and increase at the flow of radiator 18 bypass of flowing through.
In the situation that heat exchange amount is few, the aperture of opening ratio the second cooling water inlet 34a of the second cooling water inlet 34b of electric T-shaped valve 34 is large, and the flow that flows to radiator 18 increases.
In addition, be the atmosphere opening circuit from the cooling waterpump attraction 32b of section through the path that communication path 50, cooling water tank 20 arrives breathing pipes 48, but, come the connecting tube 45 of the self-loop internal pressure radiator 18 higher than the cooling waterpump attraction 32b of section and from connecting tube 49 of exhaust-heat exchanger 33 also through restriction 60,61 to cooling water tank 20 interflow, therefore, can make the pressure of cooling waterpump attraction section 32 below hydraulic head pressure.
In addition, by the downstream at motor 10 exhaust-heat exchanger 33 is set, utilizes the crushing of motor 10 parts to reduce, can make the pressure decreased that acts on exhaust-heat exchanger 33.Namely, by cutting at the downstream of described motor 10 configuration exhaust-heat exchanger 33 in described water supply pump 32 ejection sides, can with the inlet pressure of exhaust-heat exchanger 33 as " the stream crushing of pump attraction section pressure+pump ejection pressure+engine interior ", compare the amount of reduction " the stream crushing of engine interior " with " pump attraction section pressure+pump ejection pressure ".
By the attraction position as the pump at the minimum position of temperature in the chilled(cooling) water return (CWR) electric T-shaped valve 34 is set, as the Reliability Enhancement of the part of electric T-shaped valve 34.And, along with the raising of reliability, can use for a long time electric T-shaped valve 34, also can realize subduing of cost.In addition, electric T-shaped valve 34 one of is equivalent in the crushing equipment.
When engine cooling water temperature rises, when thermostat 35 becomes the state of opening to high temperature side, usually full dose is by water/water heat source exchanger 37, therefore, if detecting water temperatures, the temperature transducer 43 of the inlet side by water/water heat source exchanger 37 and the temperature transducer of outlet side 44 change, then just can the heat exchange amount of computing in water/water heat source exchanger 37.Therefore, and the situation of radiator 18 and water/water heat source exchanger 37 and row arrangement is compared, when calculating heat exchange amount, on the path of Xiang Shui/water heat source exchanger 37, do not needed flowmeter, therefore, can cutting down cost.Perhaps, compare to the situation of the flow of water/water heat source exchanger 37 with using opening ratio computing electric T-shaped valve 34 and water/water heat source exchanger 37, can alleviate computational load.
And, lead to the degassed loop of air-water separation water tank in the position setting that as exhaust-heat exchanger 33 and radiator 18, has air to retain hidden danger.Therefore, be blended in the engine cooling water of exhaust-heat exchanger 33 and radiator 18 bubble as shown in Figure 4, via connecting tube 49 and connecting tube 45 flowing into another water tank 20b.And, only having air via entering a water tank 20a connecting tube 46, air is emitted to atmosphere by breathing pipe 48.Like this, owing to being to carry out air-water separation, only have engine cooling water to turn back to the structure loop in, so can reduce the size of radiator 18, the while can prevent that also the air of cooling waterpump 32 from sneaking into (ェ ァ Ga body).In addition, the interior engine cooling water of water tank 20a suitably moved in another water tank 20b via connecting tube 47.
By in another water tank that is different from a water tank (water storage tank) 20a (air-water separation water tank) 20b, carrying out the air-water separation of high-temp. water bubble, can prevent the rising of the water temperature of water storage tank.And, because water storage tank can prevent the rising of water temperature, so can easily and at an easy rate make by enough synthetic resin.
The invention is not restricted to above-mentioned mode of execution.Example as shown in phantom in Figure 1, the water tank cooling water bottom that is provided with breathing pipe 48 also can be configured in than another water tank bottom surface eminence.Under these circumstances, the interior engine cooling water of water tank 20a can easily move in another water tank 20b via connecting tube 47.
In addition, the present invention also can be used in engine-driven heat pump.The present invention does not break away from from its spiritual or main characteristics and can implement with other various forms.Therefore, the above embodiments only for example, can not become the explanation of restriction in all points.Scope of the present invention is illustrated by claims, in specification without any restriction.In addition, belong to claims impartial scope distortion or change all within the scope of the present invention.
In addition, the application's request is based on the preference of the Patent 2008-121521 that applied on May 7th, 2008 in Japan.Its content is incorporated among the application by mentioning at this.
