The specific use cases of the above embodiment are as follows:
the energy consumption of the air conditioner is high in summer, and the company thinks that the technology of ice storage is used for cooling the house and simultaneously realizing
An energy-saving method.
In summer, in the low-ebb period of the electric charge, the electric three-way regulating valve 14 is opened, the switch B is opened, the heat exchange unit 1 continuously conveys the special ice-water mixed liquid below 0 ℃ to the ice storage tank 4 through the No. 1 circulating pump 2 and the No. 2 circulating pump 3, and the mixed liquid is stored in the heat-insulating ice storage tank 4.
In the peak period of the electric charge, the heat pump unit 1, the circulating pump 2 No. 1 and the circulating pump 3 No. 2 stop working, the second electric three-way regulating valve 11 is opened, the A is opened, the B is opened, the third electric three-way regulating valve 16 is closed, the A is opened, the cold energy is continuously conveyed to the surface air cooler 8 and the ground heating pipe or the ceiling pipe 12 in the fresh air fan 7 by the heat-preserving ice storage tank 4 through the variable frequency circulating pump 5 and the circulating pump 6 No. 3, and the house 10 reaches the set standard temperature range.
The control principle is that when the indoor temperature sensor 9 detects that the indoor temperature is low or higher than the set standard temperature range, the frequency of the variable-frequency circulating pump 5 is regulated and controlled to achieve the purpose of controlling the flow, so that the indoor temperature is accurately controlled.
If in the peak period of the electric charge, the frequency of the variable frequency circulating pump 5 is switched on to the maximum, namely the flow reaches the maximum state, after the operation is carried out for a period of time, when the indoor temperature is still higher than the set temperature range, the heat pump unit 1 and the circulating pump 2 1 are controlled to start working, the circulating pump 3 2 stops working, the first electric three-way regulating valve 14 is switched on, the second electric three-way regulating valve 14 is switched on, the third electric three-way regulating valve 16 is switched on, the cold energy is continuously transmitted to the surface cooler 8 and the ground heating pipe 12 or the ceiling pipe in the fresh air fan 7 by the heat pump unit 1, the variable frequency circulating pump 2 and the circulating pump 6 2, and finally the house 10 reaches the set standard temperature range.
If the peak of the electric charge is converted to the valley of the electric charge, the system has two states:
1. when the control system detects that the house temperature is the cold quantity control temperature transmitted by the heat pump unit 1 and the temperature inside the house is still higher than the set temperature range, the heat pump unit 1 simultaneously transmits cold quantity to the surface cooler 8 and the ground heating pipe or the ceiling pipe 12 in the new fan 7 of the ice storage tank 4 after the electricity charge is converted into the low valley, and stops transmitting cold quantity to the surface cooler 8 and the ground heating pipe 12 or the ceiling pipe in the new fan 7 until the house 10 reaches the set standard temperature range, and only transmits cold quantity to the ice storage tank 4.
2. When the control system detects that the house temperature is controlled by the cold energy transmitted by the heat pump unit 1, but the temperature in the house 10 is in the set temperature range or less than the set temperature range, the heat pump unit 1 stops transmitting the cold energy to the surface air cooler 8 and the ground heating pipe or the ceiling pipe 12 in the fresh air fan 7, and only transmits the cold energy to the ice storage tank 4.
In winter, the electric three-way regulating valve 14 is switched from A to B, the electric three-way regulating valve 11 is switched from A to B, the electric three-way regulating valve 16 is switched from A to B, and the ice storage tank 4 and the circulating pump 3 do not work. No. 1 circulating pump 2, frequency conversion circulating pump 5, the continuous circulation heat pump set 1 of No. 2 circulating pump 6 produced heat to through the heat flow of No. 1 circulating pump 2, no. 2 circulating pump 6, frequency conversion circulating pump 5 of control system control and electronic three-way control valve 11 of indoor temperature sensor 9, final indoor temperature reaches the temperature range of standard.
In the embodiment and the working principle, the heat pump unit stores the prepared ice-water mixture in the heat-insulating ice storage tank in the low ebb period of the electric charge in summer, and conveys the cold energy stored in the heat-insulating ice storage tank to a house when the electric charge is in the peak period, and the temperature in the house is adjusted by the control system to reach the standard temperature range, so that the purpose of energy saving is achieved. In winter, the ice storage tank does not work, and all heat required in the house is provided by the heat pump unit. Effectively solve the problem that the air conditioner energy consumption is high in summer among the prior art.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may apply the equivalent embodiments modified or modified by the above technical contents disclosed as equivalent variations to other fields, but any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention will still fall within the protection scope of the technical solution of the present invention.
