As shown in fig. 1-4, a constant temperature system without steam heating comprises a constant temperature water pool 3, an energy conversion device 2 and an external circulation fan 1.
An aeration pipe 31 is fixedly connected with the bottom in the constant temperature water tank 3.
An air inlet main pipe 11 is connected to an air outlet of the external circulation fan 1, and an electric control three-way valve 12 is connected to an outlet of the air inlet main pipe 11. One outlet of the electrically controlled three-way valve 12 is connected with a first air inlet branch pipe 13, and the other outlet of the electrically controlled three-way valve 12 is connected with a second air inlet branch pipe 14.
The energy conversion device 2 comprises a heat preservation box body 21, the heat preservation box body 21 is provided with an air inlet 22 and an air outlet 23, and the air inlet 22 is connected with the first air inlet branch pipe 13; an orifice plate 24 is arranged at the lower part in the heat preservation box body 21, the heat storage mechanism 7 is placed on the orifice plate 24, an internal circulating fan 25 and an electric heater 26 are fixedly connected in the heat preservation box body 21 below the orifice plate 24, and the internal circulating fan 25 blows the gas in the heat preservation box body 21 to the electric heater 26 for heating. The heated hot air is blown to the heat storage mechanism to heat the heat storage mechanism, and then the hot air with the temperature reduced enters the internal circulation fan to be heated.
The heat storage mechanism 7 comprises a carrier 72 made of heat conducting materials and a phase change working medium 71 positioned in the carrier; firstly, the melting temperature of the carrier 72 is higher than that of the phase-change working medium 71; for example, the carrier is cast iron or stainless steel, and the phase change working medium is aluminum or aluminum alloy. The volume of the phase-change working medium is smaller than that of the carrier, so that the carrier is prevented from being cracked due to volume expansion after the phase-change working medium is melted.
Meanwhile, in order to obtain the largest heat exchange area and to enable the air in the thermal insulation box to flow smoothly, the carrier 72 of the heat storage mechanism 7 is preferably spherical.
The air outlet 23 of the thermal insulation box 21 is connected with the aeration pipe 31 through an air outlet pipe 15, and the outlet of the second air inlet branch pipe 14 is connected with the air outlet pipe 15.
In this embodiment, the air outlet pipes between the outlets of the air inlet main pipe 11, the first air inlet branch pipe 13, the second air inlet branch pipe 14, and the second air inlet branch pipe 14 and the air outlet 23 of the heat preservation box body, and the air outlet pipes between the outlets of the second air inlet branch pipes and the inlets of the aeration pipes are all provided with electromagnetic valves 4.

In this embodiment, the air inlet 22 and the air outlet 23 of the thermal insulation box are respectively disposed at two ends of the thermal insulation box, and the air inlet 22 is lower than the air outlet 23. So that the cold air enters the heat preservation box body and then fully contacts with the heat storage mechanism.
When the device is used, the air inlet and the air outlet of the heat preservation box body are closed firstly, the electric heater heats air in the closed heat preservation box body by utilizing low-price valley electricity at night, and the hot air heats the heat storage mechanism, so that the phase change working medium in the heat storage mechanism is changed into a molten liquid state from a solid state, and then heat storage is carried out. When the temperature of the water in the constant-temperature water pool is higher than the set temperature, the electric heater is turned off, the external circulating fan is turned on, the corresponding electromagnetic valve is turned on, external cold air enters the heat insulation box body to be fully contacted and heated with the heat storage mechanism, and heated hot air enters the constant-temperature water pool from the aeration pipe to heat and insulate the water in the constant-temperature water pool. The second air inlet branch pipe can play a role in adjusting the air inlet volume and the air inlet temperature.
The phase-change working medium contacts cold air in the daytime, changes from a liquid state to a solid state and continuously releases heat.
The valley electricity is used for heating, the heat storage mechanism stores heat and releases heat, and low-cost operation cost and high-efficiency heating efficiency are achieved.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
