The working principle is further explained below in connection with the climate all the year round.
When the invention is in use, the water-saving device,
(I) summer: when the heat pump host 1 works for refrigeration, the water heater host 5 has hot water demand, works to heat hot water, and simultaneously provides cold quantity for water in the cold/heat circulation system 2 through an evaporator of the water heater host 5, and the addition of the cold quantity can reduce the workload of the heat pump host, which is equivalent to that an air conditioning system obtains the cold quantity freely; at the moment, the water temperature of the cooling/heating circulation system 2 is higher than the dew point temperature of indoor air and is higher than 18 ℃ in most of the time, so that the main machine of the water heater can obtain stable and excellent working conditions and high energy efficiency ratio; when the dehumidification thermoregulator 4 works, the indoor evaporator 32 plays a dehumidification role, and the indoor condenser enables heat energy to enter the cold/heat circulation system through the indoor double-channel heat exchanger and the cold/heat supply branch pipe set and radiate the heat energy to the environment through the heat pump main machine 1; the dehumidification function of the dehumidification thermoregulator ensures that the indoor heat exchanger 3 only needs to bear the sensible heat part of the indoor refrigeration load, so radiation refrigeration or dry coil refrigeration can be adopted to improve the water supply temperature under the refrigeration working condition of the heat pump main unit, thereby improving the energy efficiency ratio of the heat pump main unit; when the whole system works, the power consumption of the heat pump main machine is the main power consumption, and the refrigeration energy efficiency ratio of the whole system is obviously improved by the improvement of the energy efficiency ratio of the heat pump main machine and the cooperative work of the hot water main machine;
(II) in winter: when the heat pump host 1 is in heating operation, the water heater host 5 has hot water demand, the water heater host 5 is in operation, the condenser 55 heats the water in the liner, and meanwhile, the cold energy is released to the water in the cold/heat circulation system 2 through the evaporator of the water heater host 5, and the addition of the cold energy increases the working load of the heat pump host 1; generally, for a fixed building space and system configuration, the heating capacity of the heat pump host 1 is surplus, and the load increased by the water heater host 5 is less than 6% compared with the heating load of the heat pump host 1, so that the system can sufficiently meet the user requirements under the condition, at the moment, the water temperature in the cold/heat circulating system 2 is higher and is more than 30 ℃ at most, the temperature of the evaporation side of the water heater host 5 is high, so that the energy efficiency ratio of hot water production is high, compared with an electric water heater and a gas water heater, the energy-saving effect is obvious, the heating capacity is large, the hot water production speed is high, the habit of large hot water consumption in winter of a user is met, and the defect that the hot water speed is slow when the air temperature of the air source water heater is lower in winter is avoided; the indoor heat exchanger 3 can be a radiant heat exchanger such as a floor heating, a convection radiator such as a fan coil or a radiant convection heat exchanger such as a radiator, for a user with intermittent heating, the floor heating or the radiator has long response time in starting, and the user can feel the increase of the indoor temperature only by waiting for a long time, at the moment, the heating function of the dehumidification attemperator can be started, the heating quantity of the indoor space is forcibly increased on the basis that the indoor heat exchanger radiates the indoor heat, the indoor heating speed is accelerated, the comfort level of the user is improved, and energy waste caused by the fact that the user needs to start the heating for a long time in advance is avoided; therefore, the heat pump host, the indoor heat exchanger, the hot water host and the dehumidification temperature regulator work cooperatively, the comfort level of a user is improved, and the energy is saved and the environment is protected!
(III) spring and autumn: when hot water is needed, the circulating water pump 24 is started, the water heater host 5 detects a 'backwater temperature sensor' of the water heater host and obtains indoor dew point temperature from the main controller 16 of the heat pump host 1, and when the temperature detected by the cold/heat supply temperature sensor 26 is higher than the dew point temperature, the water heater host 5 is started to supply hot water to the inner container and release cold energy to the cold/heat supply circulating system 2; at the moment, (1) if the dehumidification thermoregulator 4 has the dehumidification requirement, the dehumidification thermoregulator carries out refrigeration and dehumidification, and simultaneously releases heat to the cold/heat circulation system 2, so that the heat released by the heat exchanger 62 of the dehumidification thermoregulator, the cold released by the water heater main machine 5 and the cold or heat generated by the heat exchanger 3 and the indoor environment are gathered into the cold/heat circulation system 2, the water temperature in the cold/heat circulation system 2 is maintained at a certain balance temperature, and if the temperature is not lower than the dew point temperature, the compressor of the heat pump main machine is not started to operate; if the water temperature in the cooling/heating circulation system 2 is lower than the dew point temperature, a compressor of the heat pump host 1 is started, and the heat pump host 1 operates according to a heating working condition to ensure that the water temperature in the whole cooling/heating circulation system is always higher than the dew point temperature; (2) If the dehumidification temperature regulator 4 has no dehumidification requirement, the dehumidification temperature regulator does not work, the cold quantity released by the water heater host 5 and the heat generated by the heat exchanger 3 and the heat exchange of the indoor environment are converged into the cold/heat circulation system, the water temperature in the cold/heat circulation system 2 is maintained at a certain balance temperature, and if the temperature is not lower than the dew point temperature, the compressor of the heat pump host 1 is not started to operate; if the water temperature in the cooling/heating circulation system 2 is lower than the dew point temperature, a compressor of the heat pump host 1 is started, and the heat pump host 1 operates according to a heating working condition to ensure that the water temperature in the whole cooling/heating circulation system is always higher than the dew point temperature; therefore, in most cases of spring and autumn, the water heater main machine 5 can indirectly utilize the heat exchanger 3 to exchange heat with the environment, so that heat is supplied to the domestic hot water, compared with the case that the conventional air source heat pump water heater needs to exchange heat with outdoor ventilation, the noise of the water heater is reduced, the size is reduced, the installation is easy, and the energy efficiency ratio is higher.
What has been described above is merely a preferred embodiment of the present invention. It should be noted that a person skilled in the art could make several modifications and variations without departing from the principle of the present invention, which should also be regarded as the protection scope of the present invention.
