In this defrosting method, the heat used in the room is transferred to the defrosting of the outdoor heat exchanger, so there is a disadvantage of destroying the heating effect
In addition, in the heating operation, in order to ensure a sufficiently heated blown air from the indoor unit, the indoor air supply is started after the piping temperature of the indoor unit is raised to a certain temperature, so there is a delay time from the start to the start of the air supply. This can also be said to be the shortcoming of the heat pump air conditioner.

Embodiment approach 1
[0030] figure 1 A schematic diagram showing a heat storage device according to Embodiment 1 of the present invention. The heat storage device 1 according to Embodiment 1 of the present invention is used in contact with the casing of the compressor of the air conditioning device, and is used to store and utilize waste heat from the compressor, and includes a heat storage tank 2 molded of polyphenylene sulfide (PPS) resin. And the cover part 3; and the thermal storage heat exchanger 5 sealed in the space surrounded by these are connected with the refrigerant|coolant piping of an air conditioner by the connection piping 68 submerged in the thermal storage tank. The thermal storage material is made of a liquid, and in this embodiment, it is filled with an ethylene glycol solution containing water. The heat storage heat exchanger 5 heats the refrigerant using the heat obtained from the heat storage material.

A heat storage device includes a heat storage material in the form of a liquid that stores heat from a heat source and a heat storage tank 2 that accommodates the heat storage material therein and has a wall to form an outer shell. The wall has a heat-transfer portion 4 to transfer heat between the heat source and the heat storage tank 2. The heat storage tank 2 has an upper end located above a level of an upper end of the heat-transfer portion 4. This configuration can increase a capacity of the heat storage material and, at the same time, efficiently increase a temperature of the heat storage material that is not in contact with the heat-transfer portion 4 due to convective heat transfer.
Description
technical field [0001] The present invention relates to a thermal storage device used in contact with a heat source and an air conditioner using the thermal storage device. Background technique [0002] In the prior art, in the heating operation of the heat pump air conditioner, in order to defrost the outdoor heat exchanger, a four-way valve is generally used to switch the flow of the refrigerant from the heating cycle to the cooling cycle, so that the high temperature and high pressure refrigeration The agent flows to the outdoor heat exchanger. In this defrosting method, the heat used in the room is diverted to defrosting the outdoor heat exchanger, so there is a disadvantage that the heating effect is impaired. In addition, in the heating operation, in order to ensure a sufficiently heated blown airflow from the indoor unit, the indoor air supply is started after the piping temperature of the indoor unit is raised to a certain temperature, so there is a delay time from ...
