The following describes the molar behavior of conditioner.

The summary of run action at first is described.

By utilizing control device 13 to switch cross valve 18, heat pump type air adjusting device 10 is set at refrigerating operaton or heating operation.

In more detail, when control device 13 switched to the refrigeration side with cross valve 18, the solid arrow of cold-producing medium shown in cross valve 18 parts was mobile like that.Consequently, outdoor heat converter 19 constitutes condenser, and indoor heat converter 21A, 21B constitute evaporimeter, form the refrigerating operaton state, and each indoor heat converter 21A, 21B are with indoor refrigeration.

At control device 13 cross valve 18 is switched to when heating side, the arrow of cold-producing medium shown in the dotted line of cross valve 18 parts is mobile like that.Consequently, indoor heat converter 21A, 21B constitute condenser, and outdoor heat converter 19 constitutes evaporimeter, forms the heating operation state, and each indoor heat converter 21A, 21B are with indoor heating.

Control device 13 is when refrigerating operaton, according to expansion valve 22A, 22B valve opening separately in the air-conditioning load control room.When heating operation, control device 13 is according to air-conditioning load control outdoor expansion valve 24 and indoor expansion valve 22A, 22B valve opening separately.

The following describes the control of gas engine 30.

The control of 13 pairs of gas engines 30 of control device, specifically, be by the oily stop valve 39 of the fuel cutoff valve 33 of control device 13 control engine fuel supply devices 31, zeroing device 34, fuel control valve 35 and adjuster 36 and engine oil feedway 37 and oily supply pump 40 etc.

But gas engine 30 is by the engine cool water cooling of conduct first medium of circulation in engine cooling apparatus 41.

Engine cooling water is with 40 ℃ temperature, from the exhaust heat exchanger of the discharge side inflow gas engine 30 of circulating pump 47.Engine cooling water flows in gas engine 30 in the discharges heat (heat of exhaust) that reclaims gas engine 30 afterwards, makes gas engine 30 coolings, is heated to about 80 ℃.

From the engine cooling water of gas engine 30 inflow paraffin triple valves 43, when engine cooling water was low temperature (for example below 80 ℃), 43B got back to circulating pump 47 from the low temperature side outlet, makes gas engine 30 rapid warming-ups.On the other hand, when engine cooling water was high temperature (for example more than 80 ℃), 43C flowed to hot water heat exchanger 44 from the high temperature side outlet.

Hot-water supply system 49 hot water for example flows in the hot water heat exchangers 44 with about 60 ℃, is warmed up to about 70 ℃ thus and supplies with to the outside.Like this, be can be used for the hot water supply by the hot-water supply system's 49 of being heated up hot water and be used for the drying of the dehumidizer of dry air adjusting device.Here, the dry air adjusting device is meant and can adopts dehumidizer, and room temperature is reduced and the conditioner of enforcement dehumidifying.

The engine cooling water that utilizes hot water heat exchanger 44 and hot-water supply system's 49 hot water to carry out heat exchange, temperature reduces (cooling) to below 65 ℃, flows to hot water triple valve 45.

When hot water triple valve 45 is no more than reference temperature value in the temperature of engine cooling water, make the engine cooling water that flows into through inlet 45A from hot water heat exchanger 44, from ON side outlet 45B,, import the exhaust heat exchanger of gas engine 30 through the suction side of circulating pump 47.Utilize the engine cool water cooling gas engine 30 that imports this exhaust heat exchanger.In addition, when hot water triple valve 45 surpasses reference temperature value in the temperature of engine cooling water, make the engine cooling water that flows into through inlet 45A from hot water heat exchanger 44 from OFF side outlet 45C guiding radiator 46.

Utilize radiator 46 to be cooled to for example 40 ℃ engine cooling water, get back to the exhaust heat exchanger of gas engine 30, make gas engine 30 coolings through the suction side of circulating pump 47.

Thus, make the switching of the hot water triple valve 45 that the engine cooling water that flows into from inlet 45A flows to the suction side of circulating pump 47 from ON side outlet 45B stable for a long time.Therefore, can make hot water triple valve 45 select the cycle long-term stability of the switching controls of switching on a ground at ON side outlet 45B and OFF side outlet 45C.

In addition,, therefore, can improve hot water heat exchanger 44 rate of heat exchange, can take out high temperature (about 70 ℃) hot water easily from hot-water supply system 49 owing to can in the scope that cooling of gas engine 30 is not produced obstacle, make cooling water keep high temperature.

As mentioned above, when conditioner 10 heating operations, control device 13 makes circulating pump 47 operations of engine cooling apparatus 41, make the engine cooling water circulation, external pump 50 is stopped, and switching controls hot water triple valve 45 makes the engine cooling water that flows into inlet 45A from hot water heat exchanger 44, from OFF side outlet 45C guiding radiator 46.Therefore, be taken into the outdoor heat converter 19 that works as evaporimeter, be used as the thermal source of evaporimeter from radiator 46 liberated heats (discharges heat of gas engine 30).

And when conditioner 10 refrigerating operatons, control device 13 makes circulating pump 47 operations of engine cooling apparatus 41, make the engine cooling water circulation, make external pump 50 operations, make hot water heat exchanger's 44 performance functions, then, at engine cooling water temperature when a reference value is following, switching controls hot water triple valve 45 makes from the major part of the engine cooling water of hot water heat exchanger's 44 outflows, imports the suction side of circulating pump 47 from ON side outlet 45B through inlet 45A.At this moment the ormal weight of the engine cooling water that flows out from hot water heat exchanger 44 always imports radiators 46 through the shunt valve 48 of cooling system.

Because the described switching controls of hot water triple valve 45, the temperature of engine cooling water can too not cooled off by described radiator 46, so hot water heat exchanger 44 rate of heat exchange improves, can take out high temperature (about 70 ℃) hot water by hot-water supply system 49, and be effectively utilized.And utilize hot water heat exchanger 44 heat exchange, the heat of cooling (heat release) inadequate engine cooling water, utilization is through the engine cooling water heat release of the shunt valve 48 importing radiators 46 of cooling system, so gas engine 30 is cooled off well by this engine cooling water.

In addition, when this refrigerating operaton, when the temperature of engine cooling water surpasses reference temperature value, control device 13 switching controls hot water triple valves 45, make the engine cooling water through inlet 45A inflow hot water triple valve 45 from hot water heat exchanger 44, from OFF side outlet 45C, guiding radiator 46.Thus, the temperature of engine cooling water reduces, and gas engine 30 is cooled off well.

Below, the discharging operation when contingency has been leaked the combustion gas that acts as a fuel in the gas box 60 is described.

Thus, even gas leakage is in gas box 60, owing to is atmospheric pressure state in the Machine Room 11, the combustion gas of leakage also can be with this order in spout member 60A → heat-resisting synthetic rubber hose 61 → outdoor heat-exchanging chamber 11A, flows out in the 11A of outdoor heat converter chamber and is discharged from.

And, even in this state, because drive chamber's external fan 20 is driven, so, be discharged to the combustion gas in the outdoor heat-exchanging chamber 11A, also can be with outer gas, be discharged to outside the machine of off-premises station 11 with the order of outdoor fan 20 → exhaust outlet 11F, be diffused in the atmosphere.

Therefore, even when reducing, leak into combustion gas in the gas box 60 and also can gas box 60 in, not reach in the 11B of Machine Room and not be detained, but discharge reliably outside the off-premises station 11 because of the air-tightness of gas box 60 such as timeliness variation.

As described above, according to present embodiment, even just in case the gas leakage that acts as a fuel in gas box 60, this combustion gas also can utilize the driving of outdoor fan 20, by outdoor heat converter chamber 11A, is discharged to the outdoor of off-premises station 11, is diffused in the atmosphere then.

More than, according to described embodiment the present invention has been described, but has the invention is not restricted to these.

In described embodiment, the situation that adopts heat-resisting synthetic rubber hose as the exhaust interconnecting part has been described, but be not limited thereto, as the tubular part that gas box and outdoor heat-exchanging chamber can be communicated with, even, just equally also can so long as hear resistance and outdoor heat-exchanging chamber are portion's material that negative pressure state also can be guaranteed the intensity of combustion gas stream.That is, also can be metal pipe arrangement etc.But, be easy to viewpoint from installing, preferably have flexible portion's material.

In addition, in described embodiment, will roll, and constitute liquid trap, but also liquid trap device can be set in addition as the mid portion of the heat-resisting synthetic rubber hose of exhaust interconnecting part.

In addition, in described embodiment, illustrate, can be with a end as the outdoor heat-exchanging chamber side of the heat-resisting synthetic rubber hose of exhaust interconnecting part, be darted in the outdoor heat-exchanging chamber, but better is, if be configured in the outer air-flow road or the suction side of outdoor fan etc. near, can more promptly discharge the combustion gas of leakage.

In addition,, be based in the hole that is arranged at central baffle, can adopt gum filler to keep the indoor negative pressure state of outdoor heat exchanger, but installation method be not limited thereto as the heat-resisting synthetic rubber hose of exhaust interconnecting part.Promptly as long as can keep the indoor negative pressure state of outdoor heat exchanger when installing, will be arranged on central baffle with the same parts of the spout member of gas box, or be utilized as other pipe arrangements and the whole bag of tricks such as hole installation that are provided with can be suitable for.

In addition, in described embodiment, any back-flow preventer is not set at the heat-resisting synthetic rubber hose of exhaust interconnecting part.But, also check (non-return) valve etc. can be set, can discharge the combustion gas of leakage thus reliably.
