Embodiment approach
[0004] Specific implementation method: a group of temperature sensors are set in the linkage control cabinet separately, and the detected temperature is the temperature of the hot water storage tank, constant temperature water tank, roof water tank, etc. During the set time period, when the temperature of the water tank detected by the temperature sensor When the temperature is lower than 42°C, the circulating pump and the host are started sequentially through the time relay to control the contactor. Realize automatic start-up heating. When the temperature of the water tank reaches 45°C, the time relay controls the contactor to turn off the main unit and the circulation pump in turn, realizing the automatic shutdown of the air source or water source heat pump heating function. The water temperature detection time is the shortest time for the unit to turn on the hot water, and the rest of the time is given way to solar heating. The general design principle is to calculate the h...

The invention relates to free solar energy preferential utilization linkage arrangement between a plurality of heat sources and a solar system. Domestic hot water is generally obtained in modes of boiler making, solar system making and heat pump making at present, the boiler making is high in energy dissipation and heavy in pollution, the solar system cannot meet hot-water requirements under rainy or extreme severe weather situations, and the heat pump making relatively saves energy and money, but the heat pump making uses energy-saving energy rather than free energy. The method is that a groups of temperature sensors are arranged in a singly-arranged linkage-controlled control cabinet, detected temperature is the temperature of a heat storage water tank, a constant temperature water tank, a roof water tank and the like, when water tank temperature detected by the temperature sensors is below 42 DEG C in a setting time quantum, a time relay controls a contactor to sequentially open a circulating pump and a host machine to achieve full-automatic heating, when the water tank temperature achieves 45 DEG C, the time relay controls contactor to sequentially close the host machine and the circulating pump to achieve the heating function of full-automatically closing an air source or water source heat pump. A main purpose is that the solar energy preferential utilization linkage arrangement is applicable to various mines and other enterprises and bath and domestic water of resident living areas. The solar energy preferential utilization linkage arrangement has the advantages of preferentially using free energy and saving energy and money, a plurality of heat sources can replenish, and a system full-automatically runs.
Description
technical field [0001] It belongs to energy-saving and environment-friendly renewable energy utilization technology. The invention relates to the production of domestic hot water, especially through the joint control control cabinet to preferentially utilize free solar energy and automatically switch to various heat sources for supplementary production of hot water when the solar energy is not enough. . Background technique [0002] At present, domestic hot water is generally produced by boilers and solar systems. Boiler production consumes a lot of energy and pollutes heavily, and solar systems cannot meet the hot water demand in rainy or extreme weather conditions. Contents of the invention [0003] In order to overcome the above shortcomings, the present invention designs a linkage function setting system for the priority utilization of free solar energy and multiple heat sources such as air source or water source heat pumps and solar energy systems: in a separate linka...
