During the bathing process of the user, the humidity in the bathroom can be gradually increased along with the increase of the bathing time in the bathroom. Especially in winter environment, in the process of bathing and hair blowing after bathing in a bathroom, because a large amount of hot water is used, the bathroom is usually full of water vapor, so that the humidity in the bathroom is very high, the body feeling humidity of a user is high, and the user is difficult to dry the body or blow the hair.
Although there are heat pump water heaters capable of dehumidifying in the existing market, because it adopts a set of system to realize the dehumidifying and water heating functions at the same time, the dehumidifying process is affected by the heating intensity of the heat pump water heater, when the user uses a large amount of hot water, the dehumidifying efficiency is reduced, the dehumidifying effect is not good, and thus the dehumidifying effect of the system is not stable.
Therefore, the heat pump water heater provided by the invention can be used for heating water in a bathroom and dehumidifying well, so that the user experience is improved.
In the embodiment of the invention, the evaporators in the heat pump unit are arranged into two independent units, and a throttling device is arranged in front of the evaporators of the two independent units. The two independent unit evaporators are respectively a first evaporator (hereinafter described as an auxiliary evaporator) and a second evaporator (hereinafter described as a main evaporator), wherein the main evaporator is used for realizing the normal hot water operation of the heat pump water heater and is basically consistent with the conventional control mode and structure; an air inlet and an air outlet which are communicated with the bathroom are respectively arranged on the auxiliary evaporator and extend to the heat pump unit body. The first fan can be arranged in an air inlet channel of the auxiliary evaporator along the direction of the air inlet and is used for sucking air in the bathroom through the air inlet, so that the air returns to the bathroom through the air outlet after passing through the auxiliary evaporator for heat exchange.
In the embodiment of the invention, when the heat pump water heater system runs, the refrigerants can respectively enter the main evaporator to realize the absorption of air heat to produce hot water; and meanwhile, the wet air enters the auxiliary evaporator, and is subjected to heat exchange through the auxiliary evaporator and then returned to the bathroom through the air outlet after condensation treatment by driving the first fan of the corresponding auxiliary evaporator, so that the heat pump water heater can suck the wet air in the bathroom through the air inlet.
In the process, because the refrigerant circulating in the auxiliary evaporator is a low-temperature low-pressure gas-liquid two-phase refrigerant, after moist high-temperature air is subjected to heat exchange, water vapor in the air can be condensed into water on the auxiliary evaporator, and therefore the dehumidification function of the heat pump water heater is achieved.
In a specific embodiment, when a user bathes, the user can select to simultaneously operate the hot water making function and the dehumidification function of the heat pump water heater, at the moment, the heat pump water heater starts the compressor, starts the first fan and simultaneously starts the first throttling device and the second throttling device according to the selection of the user, so that the compressor, the condenser in the water tank, the first throttling device and the first evaporator form a first path of refrigerant circulation loop, and the dehumidification function of the heat pump water heater can be independently realized; the compressor, the condenser in the water tank, the second throttling device and the second evaporator form a second refrigerant circulation loop, and the function of heating water by the heat pump water heater can be independently realized.
In the embodiment of the invention, the refrigerant flow in the first path of refrigerant circulation loop can be automatically adjusted by controlling the opening degree of the valve of the first throttling device, and the dehumidification strength is controlled; by controlling the opening degree of the valve of the second throttling device, the flow of the refrigerant in the second refrigerant circulation loop can be automatically adjusted, and the heating intensity is controlled. The two systems can operate independently without mutual interference, and can achieve good dehumidification effect while the heat pump water heater heats water.
In the embodiment of the invention, a temperature and humidity sensor can be arranged in an air circulation heat exchange channel of the auxiliary evaporator, namely an air inlet channel, or at an air inlet part on the heat pump unit body, so that whether the first fan is operated or not is controlled according to actual air temperature and humidity data in a bathroom, and air in the channel is driven to circularly flow to dehumidify.
In the embodiment of the invention, the throttling devices, namely the second throttling device and the first throttling device, are arranged in front of the refrigerant inlets of the main evaporator and the auxiliary evaporator, wherein the first throttling device in front of the auxiliary evaporator can be an electronic expansion valve, and the evaporation temperature of the internal refrigerant can be adjusted by adjusting the opening degree of the electronic expansion valve, so that the evaporation temperature is greatly lower than the dew point temperature of the passing air (the dew point temperature can be calculated according to the actually measured temperature and humidity of the air), thereby realizing the dehumidification effect. When the dehumidification function is not needed, the opening degree of the electronic expansion valve can be adjusted to be the lowest or even closed, so that the heat pump water heater is controlled not to perform dehumidification.
The first throttling device in front of the auxiliary evaporator can also be set to be a solenoid valve switch, and whether the auxiliary evaporator enters a dehumidification mode or not can also be realized through the solenoid valve switch.
According to the heat pump water heater provided by the embodiment of the invention, the two independent evaporator units are arranged in the heat pump unit, the throttling devices are arranged in front of the two independent evaporators, and the heat pump water heater can be controlled to independently perform heating and dehumidifying by controlling the throttling devices, so that the heating function and the dehumidifying function of the heat pump water heater are not interfered with each other, the dehumidifying effect is stable, a user can be helped to independently dehumidify air in a bathroom when the user bathes, the dehumidifying effect is obvious, and the user experience is good.
In the actual life, in the user's bathing process, because current heat pump water heater dehumidification effect is unstable, when the user weathers the hair, humidity still can be very big in the bathroom, thereby the speed that leads to the hair to weather can be very slow, to the long user of hair, the phenomenon that the hair is always blown not dry can appear even, this time that the user used the hair-dryer has prolonged greatly, simultaneously because high temperature air current blows to the user's head for a long time, also can produce certain damage to user's hair and scalp, cause a great deal of inconvenience for the user.
In order to solve the above drawbacks, based on the content of the above embodiments, as an optional embodiment, the heat pump water heater provided by the present invention may further include:
