Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Example one
As shown in fig. 1, a first aspect of the present invention provides a refrigeration method using a heat pump water heater, the refrigeration method including:
s1, acquiring a first indoor temperature in real time, and comparing the first indoor temperature with a set temperature;
s2, when the temperature sensor detects that the first indoor temperature is higher than or equal to the set temperature, the cold air path of the heat pump water heater is controlled to be communicated with the first room, the controller sets the maximum heating temperature of the heat pump water heater to be T1, when the temperature sensor detects that the first indoor temperature is lower than the set temperature, the cold air path of the heat pump water heater is controlled to be communicated with the outside, and the controller sets the maximum heating temperature of the heat pump water heater to be T2.
Preferably, the T1 is smaller than the heating temperature peak value T of the heat pump water heatermax；
The T2 is less than or equal to the heating temperature peak value T of the heat pump water heatermax。
In the technical scheme, the temperature sensor is arranged in the first room, the system can compare the first indoor temperature detected by the temperature sensor with the set temperature in real time, if the first indoor temperature detected by the temperature sensor is greater than or equal to the set temperature, the controller can automatically lead the outlet of cold air generated by the heat pump water heater to the first room, and simultaneously set the maximum heating temperature of the heat pump water heater to be T1, so that when a user heats water by using the heat pump water heater in a toilet, even if the water temperature of the heat pump water heater reaches the maximum heating temperature T1, the maximum heating temperature T1 is less than the peak heating temperature T1 of the heat pump water heatermaxTherefore, after the cold air mode of the first chamber is started, the water temperature of the heat pump water heater has a rising space, and the heat pump water heater worksThe water can be heated by absorbing heat in the air, and cold air is conveyed to the first chamber, wherein T1 can be set according to the needs of users.
When the temperature sensor detects that the temperature of the first chamber is lower than the set temperature, the temperature in the first chamber is lower, and refrigeration is not needed, so that cold air generated by the heat pump water heater is led to the outside, the controller sets the maximum heating temperature of the heat pump water heater to be T2, and T2 can be set according to the needs of a user.
The value of T1 may be set according to the user's needs, or the controller may automatically adjust the value of T1 according to the value of the first room temperature detected by the temperature sensor installed in the first room, specifically as follows:
when the first indoor temperature value detected by the temperature sensor is higher (for example, the first indoor temperature value is more than or equal to 30 ℃), the controller reduces the maximum heating temperature of the heat pump water heater and adjusts the maximum heating temperature to be T1a (wherein, T1a is less than T1), and when the first indoor temperature value detected by the temperature sensor is lower (for example, the set temperature is less than or equal to the first indoor temperature value and less than or equal to 30 ℃), the controller increases the maximum heating temperature of the heat pump water heater and adjusts the maximum heating temperature to be T1b (wherein, T1 is more than T1b and less than T1 b)max) Therefore, when the temperature in the first room is higher, more cold air is needed, the maximum heating temperature of the heat pump water heater needs to be reduced in order to enable the heat pump water heater to provide more cold air, and when the temperature in the first room is higher, the temperature in the toilet is higher, the user can meet the requirement without high water temperature in the toilet, conversely, when the temperature in the first room is relatively lower (namely the set temperature is less than or equal to the first indoor temperature value and less than or equal to 30 ℃), the cold air needed in the first room is less, and the user can meet the requirement with relatively high water temperature in the toilet, the maximum heating temperature of the heat pump water heater is increased at the moment, and the heat pump water heater meets various requirements of the user.
Through above-mentioned technical scheme, the room temperature value of first room of real-time supervision to compare it with the settlement temperature that the user set for, adjust heat pump water heater's cold wind export in real time according to the comparative result, adjust heat pump water heater's the highest heating temperature, and then guarantee the normal operating of kitchen refrigeration function better, promote user experience.
The user can determine or change the specific value of the set temperature according to the actual needs of the user, so that diversified experiences of the user can be met.
Preferably, after the step S2, the method further includes:
s3, when the first indoor temperature is higher than or equal to the set temperature, the controller adjusts the maximum heating temperature T1 set by the heat pump water heater to the peak heating temperature T1 of the heat pump water heatermaxAnd starting the heat pump water heater to provide cold air for the first chamber.
In the above technical solution, when the first indoor temperature is greater than or equal to the set temperature, the controller has set the maximum heating temperature of the heat pump water heater to T1, at this time, the user needs to cool the first room, and after the cold air mode in the first room is started, the controller will automatically change the maximum heating temperature of the heat pump water heater from T1 to T1maxThus, even if the water temperature of the heat pump water heater reaches T1 when the user starts the cold air mode, the heat pump water heater can also be used as the first room to provide cold air.
Preferably, the step S2 specifically includes:
when the first indoor temperature is higher than or equal to the set temperature, opening a first outlet of the wind direction switching device;
and when the first indoor temperature is lower than the set temperature, opening a second outlet of the wind direction switching device.
In the technical scheme, the wind direction switching device is used for switching a cold wind outlet of the heat pump water heater, cold wind generated by the heat pump water heater can be led to a first chamber or outdoors through the wind direction switching device, the wind direction switching device is provided with two wind outlets which are a first outlet and a second outlet respectively, the first outlet is communicated with the first chamber, and the second outlet is communicated with the outdoors;
thus, when the first indoor temperature is detected to be greater than or equal to the set temperature, in order to ensure the normal operation of the heat pump water heater, the maximum heating temperature of the heat pump water heater is set to be T1, then the wind direction switching device is controlled to open the first outlet, when a user needs cold wind in the first room, the cold wind mode can be started, so that the heat pump water heater is started, the generated cold wind is led to the first room through the wind direction switching device, and the value of T1 can be changed according to the needs of the user.
When the temperature in the first chamber is lower than the set temperature, namely the temperature in the first chamber is lower and no cold air is needed at all, the air direction switching device is controlled to open the second outlet, the maximum heating temperature of the heat pump water heater is set to be T2, so that the cold air generated by the heat pump water heater during working can directly flow to the outside and cannot flow to the first chamber, and the value of T2 can be changed according to the needs of users.
Wherein the first room may be one or more rooms in a kitchen, a bedroom, a living room, an office.
Like this when the user can normally use the heat pump water heater, can also refrigerate for rooms such as kitchen, provide air conditioning, still can not bring uncomfortable impression for the user, promote user experience.
Preferably, T1 is 40 ℃ or higher and T2 is 40 ℃ or higher.
