Description

Technical Field

[0001] The present invention relates to the technical field of comprehensive utilization of household energy, and in particular to an intelligent transmission and distribution system for realizing efficient comprehensive utilization of household energy by utilizing a thermodynamic reverse cycle energy storage system. Background Art

[0002] Household energy consumption accounts for an important proportion of my country's energy consumption, and household heating and cooling energy demand varies greatly with seasons and regions. When used alone, household energy supply appliances such as air conditioners and water heaters have problems such as high energy consumption, complex pipelines, low comprehensive energy efficiency, high operating costs, poor unit working conditions, and potential safety hazards.

[0003] Large central air conditioners can provide cooling and heating for multiple users at the same time, but they lack personalization and freedom. In daily life, the demand for cooling and heating will change with the seasons, living habits, etc., causing problems such as mismatch and imbalance between supply and demand. Summary of the invention

[0004] The purpose of the present invention is to provide a household energy intelligent time-space transmission and distribution system to overcome the existing problems of poor operating conditions, poor efficiency, poor comfort, dependence on units during combined cooling and heating, and difficulty in adjusting operating conditions of household air conditioners and water heaters. Energy centralized management and on-demand distribution are achieved through energy storage and cooling and heating technologies.

[0005] The technical solution adopted to achieve the purpose of the present invention is:

[0006] A household energy intelligent spatiotemporal transmission and distribution system, comprising:

[0007] The energy supply unit includes a compressor, a hot end heat exchanger, a cold end heat exchanger, an air-cooled heat exchanger, and a throttling device; the output end of the compressor is connected to the hot end heat exchanger, the throttling device, and the cold end heat exchanger in sequence through a pipeline to form a loop; the air-cooled heat exchanger is connected in parallel with the hot end heat exchanger and the cold end heat exchanger to form a loop;

[0008] The energy storage unit includes a heat carrier liquid storage tank and a coolant liquid storage tank, which are used to circulate the heat carrier and coolant for heat exchange to the hot end heat exchanger and the cold end heat exchanger respectively through a circulating pump;

[0009] The energy-consuming unit comprises an insulated water tank and a fan coil unit; a hot water circulation pump is connected between an outlet of a liquid distributor and an inlet of the insulated water tank, and a cold water circulation pump is connected between an outlet of a coolant storage tank and an inlet of a liquid distributor; an inlet of the first liquid distributor and an outlet of the second liquid distributor are connected to a heat-carrying agent storage tank, an inlet of the third liquid distributor and an outlet of the fourth liquid distributor are connected to a coolant storage tank, and two outlets of the first liquid distributor are respectively connected to pipelines between the hot water circulation pump, the cold water circulation pump and the coolant storage tank; two inlets of the second liquid distributor are respectively connected to pipelines of the insulated water tank, the fourth liquid distributor and the coolant storage tank; an inlet of the fan coil unit is connected to an outlet of the third liquid distributor, and an outlet of the fan coil unit is connected to an inlet of the fourth liquid distributor.

[0010] Among them, the hot end heat exchanger and the cold end heat exchanger are shell and tube heat exchangers, and the air-cooled heat exchanger is a fin-tube heat exchanger.

[0011] The energy supply strategy of the energy supply unit is as follows:

[0012] When the temperature in the heat carrier liquid storage tank and the coolant liquid storage tank does not reach the preset temperature, it operates in the combined cooling and heating mode; when the temperature in the heat carrier liquid storage tank reaches the set temperature, it operates in the single cooling mode; when the temperature in the coolant liquid storage tank reaches the preset temperature, it operates in the single heating mode, and when both the coolant liquid storage tank and the heat carrier liquid storage tank reach the preset temperature, the energy supply stops working;

[0013] In the combined cooling and heating mode, the heat generated by the hot-end heat exchanger is driven by the heat carrier circulation pump to flow the heat carrier to the heat carrier storage tank, and the cold energy generated by the cold-end heat exchanger is driven by the coolant circulation pump to flow the coolant to the coolant storage tank.

[0014] In the single cooling mode, the hot end heat exchanger and the heat carrier circulation pump stop working, while the air-cooled heat exchanger works to undertake the refrigerant condensation function. The function conversion is achieved by opening and closing the valve.

[0015] In the single heating mode, the cold end heat exchanger and the refrigerant circulation pump stop working, while the air-cooled heat exchanger works to take on the refrigerant evaporation function. The function conversion is achieved by opening and closing the valve;

[0016] The energy consumption unit can realize three operation modes: summer air conditioning hot water supply mode, winter heating hot water supply mode, and domestic hot water supply mode;

[0017] In the domestic hot water supply mode, the hot water circulation pump is turned on to drive the working medium to flow in the pipeline, exchange heat from the heat carrier storage tank to increase the temperature, and then flow through the distributor 1, the hot water circulation pump, the insulation water tank, the distributor 2 and return to the heat carrier storage tank;

[0018] In the summer air conditioning and hot water co-supply mode, the cold water circulation pump is turned on to drive the working medium to flow in the pipeline, exchange coldness from the coolant storage tank to reduce the temperature, flow through the cold water circulation pump, liquid distributor three, fan coil, liquid distributor four and return to the coolant storage tank, the hot water circulation pump is turned on to drive the working medium to flow in the pipeline, exchange heat from the heat carrier storage tank to increase the temperature, flow through the liquid distributor one, hot water circulation pump, insulation water tank, liquid distributor two and return to the heat carrier storage tank;

[0044] In the winter heating and hot water co-supply mode, the cold water circulation pump 18 is turned on to drive the working medium to flow in the pipeline, exchange heat from the heat carrier storage tank 1 to increase the temperature, and flow through the distributor 1 13, valve 19, cold water circulation pump 18, distributor 3 15, valve 23, fan coil 25, distributor 4 16, valve 21, distributor 2 14 and return to the heat carrier storage tank 1; the hot water circulation pump 17 is turned on to drive the working medium to flow in the pipeline, exchange heat from the heat carrier storage tank 1 to increase the temperature, and flow through the distributor 1 13, hot water circulation pump 17, valve 22, insulation water tank 24, distributor 2 14 and return to the heat carrier storage tank 1.

[0045] It should be noted that, in the present invention, the fan coil unit can work independently, and the system design ensures that as long as there is one fan coil unit in use, the cold water circulation pump will work.

[0046] The present invention achieves the effect of overcoming the problems of poor operating conditions, poor efficiency and poor comfort of existing household air conditioners and water heaters through centralized energy storage and cooling and heating technologies.

[0047] The present invention achieves the effect of integrating household energy supply appliances and saving pipelines and main components by optimizing the structural design.
