Abstract

PROBLEM TO BE SOLVED: To maintain an energy consumption efficiency in the best stage by sending antifreeze solution stored and cooled in a tank to a water heat exchanger of a heat pump unit, and controlling temperature of the fed solution to a temperature effective to heat exchange for cooling. SOLUTION: Antifreeze solution 3 is introduced into a tank 2 heat insulated by a heat insulator 1, and the solution 3 is circulated and cooled via an antifreeze solution cooling pump 5 by a cooler 4 provided separately by power temporarily conducted. The cooled solution 3 stored in the tank 2 is sent to a water heat exchanger 8 of a heat pump unit 7 via a pump 6 for the heat pump, and temperature of the sent solution 3 is controlled to a temperature effective to heat exchange for cooling. Thus, a gap between the time of using the power and the time of no use can be minimized, and an energy consumption efficiency can be maintained in the best state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for maintaining a high level of energy consumption efficiency of cooling and heating by utilizing electricity that is temporarily supplied such as midnight power.

[0002]

2. Description of the Related Art In a conventional air conditioner, during cooling, a refrigerant warmed indoors is radiated by an outdoor unit, but its efficiency is reduced when the outside air temperature is high. In addition, at the time of heating, the refrigerant cooled in the room absorbs the outside temperature by the outdoor unit. However, when the outside temperature is low, the efficiency is reduced. That is, the energy consumption efficiency decreases when the outside air that needs cooling is hot, and decreases when the outside air that needs heating is cold, and the power consumption increases. As another conventional technique, there is a technique in which liquid is frozen by midnight power or the like, and the cool air is directly used for cooling. However, the capacity of the freezing tank is large, and the cooling capacity itself is limited.

[0003]

Therefore, the present invention is an apparatus capable of maintaining the highest energy consumption efficiency of the air conditioner during air conditioning, and the heat source for that is provided by energization during a time when power is excessive. Can do things.

[0004]

This configuration will now be described. (B) The known antifreeze 3 in the tank 2 insulated by the heat insulating material 1 is cooled to below freezing by the surplus electric power. It is also heated to high temperatures. (B) The antifreeze liquid 3 is sent to the known water heat exchanger 8 through the pump 6 by adjusting the temperature to the most efficient temperature when the heat pump unit 7 performs work by the known control device 13. (C) The antifreeze 3 can be cooled to below freezing by a known cooler 4. Therefore, the temperature of the antifreeze 3 sent to the water heat exchanger 8 is low. (D) During cooling, the heated heat from the room returns to the water heat exchanger 8 from one side via the fan unit 11, the pump 10, and the water heat exchanger 9 for cold / hot water. With respect to this heat, the antifreeze 3 cooled by the apparatus is circulated while adjusting the flow rate so that the heat exchanger 9 for cold / hot water can exchange heat most efficiently. (E) Since the antifreeze 3 is heated to a high temperature by the heater 12 during heating, the temperature of the antifreeze 3 sent to the water heat exchanger 8 is high. (F) Contrary to the time of heating and cooling, the heat sent from the indoor side to the water heat exchanger 8 is cooled, so that the antifreeze 3 heated by the device is cooled by the heat exchanger 9 for cold and hot water. Circulation is performed while adjusting the flow rate so that the heat exchange with the water heat exchanger 8 can be performed most efficiently.

[0005]

The present invention has the above-described structure. Therefore, even in intense heat and even when the temperature is below freezing in midwinter, a stable heat source that is not affected by the outside temperature is provided for cooling and heating in the heat pump unit by cooling and heating heat stored using surplus power such as midnight power. it can. That is, the energy consumption efficiency of the cooling and heating device can be maintained at the best place.

[0006]

Next, an embodiment of the present invention will be described. (A) An embodiment of the device in which the cooling layer and the heat storage layer are separated to store heat in the heat storage brick during heating and the catalyst is heated by the warmed surrounding air. (B) An embodiment of the device in which a cooling layer and a heat storage layer are separated and cool air is stored in a known packed cooling liquid during cooling, and the catalyst is cooled with an antifreeze liquid cooled by the cooling liquid.

[0007]

[Effects of the Invention] During cooling when everyone is hot and when heating when everyone is cold, everyone uses electricity together. At this time, since the energy consumption efficiency of the cooling device and the heating device is reduced, the power demand is maximized, and the power supply may be tight. Furthermore, at midnight, the power demand is minimized and the equipment may be left over. In order to reduce such a gap between when power is used and when power is not used, it is necessary to level power usage. Such a device can alleviate such a situation. In addition, surplus power at midnight can be used, which has the effect of improving power generation efficiency.
