Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 schematically illustrates an air-powered water heater according to some embodiments of the present invention, including a heat exchanger, a refrigerant cycle portion connected to a refrigerant cycle side of the heat exchanger, and a water heating portion connected to a water heating side of the heat exchanger. The water heating part provides a water source, so that the water source obtains heat and realizes water outlet through the heat exchanger.
In this specification, the four ports of the four-way valve 4 are respectively denoted by D, E, S, C, and the specific connection mode of the four-way valve 4 is not limited to the following mode as long as the relevant functions can be achieved, and those skilled in the art may make certain changes to the specific connection mode.
Example one
Refrigerant cycle section
Referring to fig. 1 to 3, the refrigerant cycle portion includes an accumulator 1, an expansion valve 2, an air heat exchanger, a gas-liquid separator 3, a compressor, a four-way valve 4, and a protection switch 5.
The refrigerant circulation side of the heat exchanger, the reservoir 1, the expansion valve 2, the air heat exchanger, the gas-liquid separator 3 and the compressor are sequentially connected in a circulating manner, and the four-way valve 4 is respectively connected with the air heat exchanger, the compressor, the gas-liquid separator 3 and the refrigerant circulation side of the heat exchanger.
The four-way valve 4 has a port D connected to the outlet of the compressor, a port E connected to the refrigerant circulation side of the heat exchanger, a port S connected to the inlet of the compressor via the gas-liquid separator 3, and a port C connected to the air heat exchanger.
The expansion valve 2 is a bidirectional expansion valve 2. The protection switch 5 is arranged to close the compressor when the discharge pressure of the compressor exceeds a preset value.
The air energy heat exchange realized by the refrigerant circulating part can provide two functional modes, and the working processes are respectively described below.
(1) Hot water mode
In this mode, heat from the outdoor environment is absorbed by the air heat exchanger, and heat is released by the heat exchanger into the water flow to be heated, so that the water flow is heated without affecting the indoor temperature.
As shown in fig. 1-2, the refrigerant circulation path is such that the refrigerant absorbs heat and evaporates in the air heat exchanger, passes through the ports C and S of the four-way valve 4 in sequence, enters the gas-liquid separator 3, enters the compressor for supercharging, passes through the ports D and E of the four-way valve 4 in sequence, is subjected to heat dissipation and condensation on the refrigerant circulation side of the heat exchanger, passes through the liquid reservoir 1, is depressurized by the expansion valve 2, reenters the air heat exchanger after depressurization, and continues to circulate for the next time.
(2) Defrost mode
In this mode, the heat exchanger absorbs heat from the water source and releases it to the air heat exchanger, causing frost on the air heat exchanger to melt. The water source preferably adopts room pipe network backwater in the backwater end.
As shown in fig. 3, the refrigerant circulation path is such that the refrigerant is subjected to heat dissipation and condensation in the air heat exchanger, then is subjected to pressure reduction by the expansion valve 2, then passes through the liquid storage device 1, enters the refrigerant circulation side of the heat exchanger to absorb heat for evaporation, sequentially passes through the ports E and S of the four-way valve 4, enters the gas-liquid separator 3, then enters the compressor to be pressurized, sequentially passes through the ports D and C of the four-way valve 4, reenters the air heat exchanger, and continues to circulate for the next time.
(II) Water heating section
The water heating part comprises a three-way valve 6, a first throttle valve 7, a second throttle valve 8, a one-way valve 9, a hot water tank and a water pump 10.
The inlet of the three-way valve 6 is connected with the tap water inlet end and the water return end of the room pipe network through the one-way valve 9, and the outlet of the three-way valve 6 is connected with the inlet of the first throttle valve 7, so as to communicate one of the water return end or the tap water inlet end with the inlet of the first throttle valve 7, thereby realizing water inlet from the water return end (refer to fig. 2) or the tap water inlet end (refer to fig. 1). The one-way valve 9 may be omitted.
The outlet of the first throttle valve 7 is connected with the inlet of the water heating side of the heat exchanger, and the outlet of the water heating side of the heat exchanger is connected with the hot water tank. After entering the hot water tank, the water is pressurized and delivered to a room where the water is used by the water pump 10. The first throttle valve 7 is used for controlling the water inflow of the water heating side of the heat exchanger, the first throttle valve 7 adopts a condensing pressure valve and is used for adjusting the water inflow according to the exhaust pressure of the compressor, and the opening degree of the valve is adjusted by sensing the pressure change of the refrigerant, so that enough water flow can pass through, and the improvement of the heat exchange efficiency and the constancy of the water outlet temperature are facilitated.
The inlet of the second throttle 8 is connected to the outlet of the three-way valve 6 and its outlet is connected to the inlet of the water heating side of the heat exchanger, and in defrost mode, water flow can enter the heat exchanger through the second throttle 8 instead of the first throttle 7, see fig. 3.
The hot water tank is connected with an outlet of a water heating side of the heat exchanger, and the hot water tank is set to be directly discharged, namely is not circularly connected with the heat exchanger, so that water in the hot water tank is not circularly heated. In the prior art, a heat exchanger continuously and circularly heats hot water in a hot water tank, and the heating efficiency is lower because the temperature of a water source entering the heat exchanger is higher and the heat energy is not fully utilized.
Example two
Referring to fig. 4 to 6, the refrigerant cycle portion of the present embodiment is the same as that of the first embodiment except for the water heating portion. The water heating part comprises a three-way valve 6, a first throttle valve 7, a one-way valve 9, a hot water tank and a water pump 10, and does not comprise a second throttle valve 8. The first throttle valve 7 is preferably an electric throttle valve. The adjustment of the outlet water temperature can be directly realized through the adjustment of the opening of the electric throttle valve.
The inlet of the three-way valve 6 is connected with the tap water inlet end and the water return end of the room pipe network through the one-way valve 9, and the outlet of the three-way valve 6 is connected with the inlet of the first throttle valve 7, so as to communicate one of the water return end or the tap water inlet end with the inlet of the first throttle valve 7, thereby realizing water inlet from the water return end (refer to fig. 5) or the tap water inlet end (refer to fig. 4).
The outlet of the first throttle valve 7 is connected with the inlet of the water heating side of the heat exchanger, and the outlet of the water heating side of the heat exchanger is connected with the hot water tank. After entering the hot water tank, the water is pressurized and delivered to a room where the water is used by the water pump 10. The first throttle valve 7 is used to control the water inflow of the water heating side of the heat exchanger.
The hot water tank is connected with an outlet of a water heating side of the heat exchanger, and the hot water tank is set to be directly discharged, namely is not circularly connected with the heat exchanger, so that water in the hot water tank is not circularly heated. In the prior art, a heat exchanger continuously circularly heats hot water in a hot water tank, and the heating efficiency is low because the temperature of a water source entering the heat exchanger is high and the heat energy is not fully utilized.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made, and combinations of features described above, including combinations of features from different embodiments described above, without departing from the spirit of the invention.
