According to said structure present embodiment is described below.Illustrate that at first cold-producing medium passes through the operation of heat pump overview of outdoor heat converter.
1. operation of heat pump:
Make indoor warming after the high-temperature high-pressure refrigerant of being discharged by compressor 1 carries out heat exchange through cross valve 2 inflow indoor heat exchangers 10, with room air, the amplifying valve 5 of flowing through again becomes the cold-producing medium of low-temp low-pressure.Then, this cold-producing medium is inhaled into compressor 1 once more by two-port valve 7, after outdoor heat converter 3 places are by the outdoor air draw heat.During this period, two-port valve 8 cuts out.Above-mentioned operation of heat pump process is by control device 20 controls.
The following describes the flow through cold-producing medium heating operation situation of cold-producing medium heating circuit 12 of cold-producing medium.
2. cold-producing medium heating operation:
During the operation beginning, open two-port valve 6, close two-port valve 7 and 8, compressor 1 brings into operation.Like this,, close two-port valve 6, open two-port valve 8, beginning cold-producing medium heating operation cold-producing medium suction chamber inner exchanger 10 1 rear flank of being detained in the outdoor heat converter 3.At this moment, the high-temperature high-pressure refrigerant of discharging from compressor 1 flows to indoor heat converter 10 through cross valve 2, and subsequently, the cold-producing medium two-port valve 8 of flowing through after to indoor heat release and by expansion valve 5 decompressions is inhaled into compressor 1 after being heated once again by cold-producing medium heater 4.
At above-mentioned heating run duration, the gasifier 15 that heats through gasification heater 15a makes fuel gasification, is delivered to cold-producing medium heater body 4a one side by the fuel after gasifying from nozzle 4c.The fuel of delivering to cold-producing medium heater body 4a through nozzle 4c by igniter 4b igniting after, beginning heating and cooling agent heater body 4a.Above-mentioned cold-producing medium heating operation is by control device 20 controls.
The following describes by the handoff procedure of cold-producing medium heating operation to operation of heat pump.At first, the electric current of igniter 4b detects in 20 pairs of current refrigerant heating of control device running status, if be in fired state, then carries out the control of stopping burning of halt firearm 4b action.After confirming that igniter 4b stops burning, then dwindle the aperture (50%) of the aperture of expansion valve 5 to appointment.Then, control device 20 is opened two-port valve 7, sets the cutting-in speed of fan 9 simultaneously, closes two-port valve 8 then.
At this moment, if the running frequency Hz of compressor 1 when setting C is following, then makes the running frequency of this compressor 1 rise to setting C.If the running frequency Hz of this compressor 1 is higher than setting C, the running frequency before then keeping switching.
Subsequently, make the running frequency of compressor 1 remain on setting C a period of time, according to by room temperature detector a
1Detected room temperature Ta and remote controller a
3The temperature T of setting
s, enter common operation of heat pump.
Like this, move when operation of heat pump switches in the cold-producing medium heating, owing to can make the running frequency Hz of compressor 1 when being lower than setting C, rise to setting C, so, can carry out reposefully to the conversion of operation of heat pump.In above-mentioned handoff procedure, because switching is what to carry out smoothly under the running frequency stable state of compressor 1, so can prevent that compressor from sending abnormal sound.
The following describes by operation of heat pump to cold-producing medium heating running status and handoff procedure.
At first, when service ability that compressor 1 the is sent instruction output of compressor 1 (promptly to) when being higher than setting (V), then makes this service ability instruction force to drop to V, to guarantee the heater 15c energising station service power that gasifies.When the temperature of the gasifier 15 that is heated by gasification heater 15c is higher than setting (for example being 200 ℃), enter the running status of refrigerant-recovery.
Here said refrigerant-recovery operation is meant and will be trapped in the running that outdoor heat converter 3 interior refrigerant-recovery arrive indoor heat converter 10 1 sides.Specifically, at first close two-port valve 7 and 8, fan 9 is shut down, make compressor 1 move certain hour with under the frequency then, cold-producing medium is received indoor heat converter 10 1 sides in recovery.
When the temperature of gasifier 15 reaches 300 ℃ and refrigerant-recovery and finishes, carry out IGNITION CONTROL.If when the temperature of gasifier 15 reaches 300 ℃ before refrigerant-recovery finishes, the temperature of gasifier 15 is adjusted to 220 ℃～260 ℃.When the temperature of gasifier 15 does not reach 300 ℃, proceed the refrigerant-recovery operation.
The following describes the IGNITION CONTROL process.At first the running frequency of compressor 1 is adjusted to the spark rate Hz of setting, made the igniting revolution operation of motor (not shown) of the nozzle 4c of cold-producing medium heater 4 then, thereby make igniter 4b begin action to set.
In this case, after gasifier 15 gasification and the fuel that is sent to nozzle 4c are by igniter 4b igniting, cold-producing medium heater 4a is heated.
When fuel by igniter 4b igniting back, compressor 1 the service ability instruction operation during according to starting, then, according to by room temperature detector a
1Detected room temperature Ta and by remote controller a
3The design temperature Ts that sets carries out common cold-producing medium heating operation.
When excessive,, guaranteeing the gasification heater 15c required electric power (energy) of cold-producing medium heater 4, successfully carry out above-mentioned switching by this output being dropped to the value of setting by the output of operation of heat pump compressor 1 when cold-producing medium heating operation is switched.
It still is the operation of heat pump pattern that control device 20 determines to adopt cold-producing medium heating operational mode according to the content of table shown in Figure 2.That is to say that as shown in Figure 2, control device 20 is determined operational mode according to the difference of outdoor temperature To, room temperature Ta and design temperature Ts.In addition,, make it keep certain and lag behind, when operation of heat pump switches and by operation of heat pump, switching the afore mentioned rules value to cold-producing medium heating operation by cold-producing medium heating operation for the outdoor temperature To setting that switches cold-producing medium heating operational mode and operation of heat pump pattern.
At this moment, control device 20 calculates from the output of compressor 1 and the burning output of cold-producing medium heater 4, once exports required necessary CO
2Discharge capacity is obtained outdoor temperature setting To and is made CO
2Discharge capacity is a minimum of a value.
For example, under the operation of heat pump state, according to outdoor temperature To, power demand, service ability and air conditioner load are as shown in Figure 3.And under the state of cold-producing medium heating operation, required electric power, service ability and air conditioner load are as shown in Figure 4.
Now the efficient in supposition thermal power plant is 0.35, and the efficiency of combustion during cold-producing medium heating operation is 0.85, if the COP of operation of heat pump greater than 2.4, then operation of heat pump can reduce the relevant CO of primary energy
2Discharge capacity.
In addition, control device 20 also can be according to the predefined electricity charge and fuel oil expense, at first calculating according to the output of the compressor 1 of outdoor temperature To correspondence and 4 outputs of cold-producing medium heater must operating cost, and minimum with this operating cost then be that to determine to adopt operation of heat pump still be that cold-producing medium heats and moves to prerequisite.
As shown in Figure 2, control device 20 is determined the switching of operation of heat pump and cold-producing medium heating operation according to the difference of outdoor temperature To and design temperature Ts and room temperature Ta, but, when selecting high heating temperature to move, can force to carry out cold-producing medium and heat operation and reach the purpose that high heating temperature is moved.When needs keep service ability (as being in quiet sleep running status), can force to carry out operation of heat pump.
As shown in Figure 1, the temperature in the indoor heat converter 10 is by indoor heat converter temperature sensor a
4Detect, as this indoor heat converter temperature sensor a
4When the temperature that detects was higher than certain specified temp, the service ability of the low compressor 1 of control device 20 mandatory down rose to prevent condensing pressure.
In this case, the design temperature of cocoa reduction compressor 1 service ability is pressed cold-producing medium heating operational mode or operation of heat pump patterns of change respectively.That is to say under cold-producing medium heating running status, when by indoor heat converter temperature sensor a
4When the temperature that records is higher than first design temperature, should reduce the ability of compressor 1.Under the operation of heat pump state, when by indoor heat converter temperature sensor a
4The temperature that records is lower than first design temperature but when being higher than second design temperature, also should reduces the ability of compressor 1.
Like this, under cold-producing medium heating running status, improve condensation temperature and carry out the control of height heating temperature, under the operation of heat pump state, reduce the load that condensation temperature alleviates compressor 1, with anti-tamper compressor 1.
