According to the intelligent backwater air energy heat pump water heater, cold water in the pipeline can not be wasted before the hot water is flown out, the waiting time of the cold water to be drained away can be saved, and the heat pump water heater has the advantages of water resource saving, convenient for use, comfort and the like.
Description
The invention belongs to the air source heat pump water heater technical group field, especially a kind of air energy heat pump water heater that can reclaim cold water.
At present, traditional air energy heat pump water heater at a distance from a period of time do not use hot water, the water in the hot water pipeline will become cold water; When using hot water, must wait for that ducted cold water flows to end, hot water just can flow out; Not only waste water resource and time, use also extremely inconvenient.
In order to overcome the technical disadvantages that above-mentioned existing air energy heat pump water heater exists, the present invention provides a kind of intelligent backwater air energy heat pump water heater.
The technical solution adopted for the present invention to solve the technical problems is that it is made up of main frame, water tank, current inductor and controller.Water circulating pump, electric T-shaped valve, control circuit board, return water temperature sensor, heat exchanger and refrigeration system are housed in the main frame, and main frame is provided with cyclic water outlet, circulation water inlet, backwater and advances to take over mouthful.The water inlet end of water circulating pump connects an electric T-shaped valve in main frame; Two interfaces in addition of electric T-shaped valve advance to take over mouth with circulation water inlet, backwater respectively and are connected; The return water temperature sensor is arranged on the water return pipeline; The water side of water circulating pump and heat exchanger, cyclic water outlet are taken over a mouthful polyphone, and the refrigerant tubing in the heat exchanger connects refrigeration system.Water tank is provided with that cold water advances, hot water goes out, circulation is intake, cyclic water outlet is taken over mouthful and the water tank temperature sensor; Circulation water inlet on the main frame, cyclic water outlet take over mouth respectively with water tank on cyclic water outlet, circulation water inlet take over mouthful and connect, form water fluorine heat exchange closed circuit.Hot water pipeline is arranged a water return pipeline, and water return pipeline connects backwater and advances to take over mouth, forms the backwater circulation loop; Or connect a check valve at the end of hot water pipeline; The port of export of check valve connects cold water pipes, cold water pipes is connected backwater advance to take over mouthful, advances to take over mouthful to connect a check valve at the cold water of water tank; The arrival end of check valve connects cold water pipes, utilizes cold water pipes to form the backwater circulation loop.The current inductor is installed on the hot water out pipe road, and controller, current inductor, water tank temperature sensor, return water temperature sensor, water circulating pump, electric T-shaped valve link to each other with the control circuit board circuit respectively.
When the return water temperature sensor detects temperature and is lower than the detected temperature of water tank temperature sensor; Give control circuit board with this transfer of data; Control circuit board is provided with the control electric T-shaped valve according to controller and promptly opens backwater inlet pipe road, closes the circulation inlet channel; Start the hot water that water circulating pump draws back the water in the hot water pipeline in the water tank in heating, the water tank again and charge in the pipeline, make the water temperature in the hot water pipeline remain consistent with the interior water temperature of water tank.Controller has regularly backwater time parameter setting, the backwater temperature difference value parameter is set.
When controller is set at regularly backwater state following time; As be set at: 7:00-8:30,11:30-12:30,17:00-20:30 (this time period can according to the hot water custom and require freely to set), at this moment between water temperature in section interior hot water pipeline all can keep with water tank in water temperature consistent.As section is outer at this moment when needing to use hot water; Can use manual backwater function; Earlier with hot water tap's switch once, the current inductor is sensed water-flow signal and is transferred to control circuit board, and control circuit board is provided with the control electric T-shaped valve according to controller and promptly opens backwater inlet pipe road, closes the circulation inlet channel; Start the hot water that water circulating pump draws back the cold water in the hot water pipeline in the water tank in heating, the water tank again and charge in the pipeline, controller can be provided with manual backwater duration of runs.
The backwater temperature difference value of controller is set: stop temperature approach like: backwater and be set at 8 ℃, backwater and start temperature approach and be set at 10 ℃ (this temperature approach can require rationally set according to reality; But starting temperature difference setting value, backwater must stop temperature difference setting value) greater than backwater; At this moment; Like the detected real-time water temperature of water tank temperature sensor is 50 ℃; When the return water temperature sensor detected real time temperature and reaches 42 ℃ (50 ℃-8 ℃=42 ℃), control circuit board stopped the return water system running according to this signal; When the detected real time temperature of return water temperature sensor was lower than 40 ℃ (50 ℃-10 ℃=40 ℃), control circuit board was according to this signal enabling return water system running, and so periodic duty keeps the water temperature in the hot water pipeline.
Owing to adopt such scheme, the invention has the beneficial effects as follows, when using hot water, no cold water is emitted, open leading instant-heating and outlet hot, conserve water resource and time, raising comfort.
