As shown in Figure 2, a kind of control method of recuperation of heat control circuit of air-conditioner is carried out according to the following procedure:
Step a. is according to user's request, and when heat recovery function opened by needs, close single-pole switch K1, power supply is connected indicator lamp XH1 and lighted, simultaneously for follow-up water temperature Detection & Controling unit provides working power;
Step b. temperature controller WKQ for detecting the temperature of water in recuperation of heat water tank, and judges whether water temperature meets recuperation of heat condition, and when meeting recuperation of heat condition, the normally opened contact WKQ-1 of temperature controller WKQ closes;
When the setting value of water tank water temperature lower than temperature controller WKQ, the normally opened contact WKQ-1 that temperature controller WKQ carries converts conducting state to by off-state, for subsequent control circuit provides working power; Otherwise the normally opened contact WKQ-1 that temperature controller WKQ carries is in off-state all the time.
Step c open type pressure switch HP judges whether the system pressure of air-conditioner exhaust side meets recovering condition, and is automatically converted to closure state when meeting pressure recovery condition by off-state;
When the state being arranged on the open type pressure switch HP of the system pressure detecting unit in air-conditioner system meets recuperation of heat condition, be automatically converted to closure state by off-state, further for follow-up control circuit provides working power; When system pressure can not meet recuperation of heat condition, pressure switch HP still keeps former off-state.
Steps d. the normally-closed contact SJ-1 carried by delayed type time relay sj connects the water pump relay PUMP and the first intermediate relay ZJ 1 that control water pump operation, and water pump operation signal lamp XH2 lights simultaneously;
After pressure switch HP is automatically converted to closure state by off-state, the normally-closed contact SJ-1 that first the water pump relay PUMP of control water pump operation, the first intermediate relay ZJ 1 are carried by delayed type time relay sj obtains working power and starts working, and therefore water pump operation signal lamp XH2 also can be lit; Before the delay time of time relay sj setting does not arrive, the normally-closed contact SJ-1 that water pump relay PUMP, the first intermediate relay ZJ 1 and water pump operation signal lamp XH2 rely on time relay sj to carry obtains working power;
Step e. is after pressure switch HP is automatically converted to closure state by off-state, and delayed type time relay sj is started working because obtaining working power; Delayed type time relay sj setting delay time arrive after its normally-closed contact SJ-1 carried is automatically converted to off-state by closure state, normally opened contact SJ-2 is automatically converted to closure state by off-state;
If step e.1. after water pump brings into operation, delayed type time relay sj setting delay time arrive before during this period of time in, in heat recovery water system, discharge can meet when being arranged on heat recovery water intrasystem water flow switch SL setting value, water flow switch SL is automatically converted to closure state by former off-state, for the second intermediate relay ZJ 2 provides working power, second intermediate relay ZJ 2 coil working, its two couples of normally opened contacts ZJ2-1, ZJ2-2 carried are automatically converted to closure state by former off-state;
After the first normally opened contact ZJ2-1 that second intermediate relay ZJ 2 carries is automatically converted to closure state by former off-state, further for water pump relay PUMP, the first intermediate relay ZJ 1 provide reliable working power, therefore water pump operation signal lamp XH2 also keeps illuminating state; After the delay time of time relay sj setting arrives, the first normally opened contact ZJ2-1 that water pump relay PUMP, the first intermediate relay ZJ 1 and water pump operation signal lamp XH2 will rely on the second intermediate relay ZJ 2 to carry obtains working power;
After the second normally opened contact ZJ2-2 that second intermediate relay ZJ 2 carries is automatically converted to closure state by former off-state, and after the delay time of time relay sj setting arrives, current normal signal indicator lamp XH4 obtains working power by the contact SJ-2 of time relay sj, the second normally opened contact ZJ2-2 of the second intermediate relay ZJ 2 and keeps illuminating state, prompting current are normal, and therefore the 3rd intermediate relay ZJ 3 coil also obtains working power.
After first relay ZJ1 coil obtains power work, the normally-closed contact ZJ1-1 that it carries converts off-state to by former closure state, and current abnormal signal indicator lamp XH3 keeps OFF state because obtaining working power.
If step e.2. after water pump brings into operation, delayed type time relay sj setting delay time arrive before during this period of time in, in heat recovery water system, discharge can not meet when being arranged on heat recovery water intrasystem water flow switch SL setting value, water flow switch SL still keeps former off-state, second intermediate relay ZJ 2 can not obtain working power, and its two couples of normally opened contacts ZJ2-1, ZJ2-2 carried still keep former off-state;
After the delay time of time relay sj setting arrives, therefore the normally-closed contact SJ-1 that it carries can disconnect, because the normally opened contact ZJ2-1 of the second intermediate relay ZJ 2 remains open state, water pump relay PUMP, the first intermediate relay ZJ 1 quit work because of power supply of losing the job, and water pump operation signal lamp XH2 also extinguishes because losing the job power supply;
Due to the first intermediate relay ZJ 1 because power supply of losing the job quits work, the normally-closed contact ZJ1-1 that it carries returns to former closure state, current abnormal signal indicator lamp XH3 can obtain working power by the ZJ1-1 of the contact SJ-2 of time relay sj, the first intermediate relay ZJ 1 and keep illuminating state, and prompting current are abnormal;
After the delay time of time relay sj setting arrives, therefore the normally-closed contact SJ-2 that it carries can close, because the normally opened contact ZJ2-2 of the second intermediate relay ZJ 2 remains open state, current normal signal indicator lamp XH4 keeps former OFF state because not obtaining working power, and the 3rd intermediate relay ZJ 3 coil can not obtain working power.
Step f. is by above-mentioned, if current are normal, then therefore the 3rd intermediate relay ZJ 3 coil also obtains working power, the normally-closed contact of its one group of 3 contact ZJ3-1 carried disconnects, cut off the power supply of bypass solenoid valve PTF, normally opened contact closes simultaneously, for recuperation of heat magnetic valve HSF provides working power, and then realizes the control to recuperation of heat.
Step g. by above-mentioned, if current are abnormal, then the 3rd intermediate relay ZJ 3 coil is because obtaining working power, the state of its one group of 3 contact ZJ3-1 carried remains unchanged, bypass solenoid valve PTF powers in running order by normally-closed contact, recuperation of heat magnetic valve HSF can not obtain working power because normally opened contact cannot close, and also just cannot realize recuperation of heat.
