The objective of the invention is to overcome the deficiencies in the prior art and a kind of air source hot pump water heater energy-saving control method is provided, it can select best opening time section according to Teat pump boiler design temperature, water tank actual temperature and outdoor environment temperature, makes Teat pump boiler be in efficient running status.
In order to achieve the above object, the present invention is achieved in that it is a kind of energy-saving control method of air source hot pump water heater, it is characterized in that step is as follows:
(a) when the Teat pump boiler energising, the user carries out artificial mode by input module and energy saver mode is selected; After selecting energy saver mode, set water use peak time t1, water temperature ceiling temperature T3 and water temperature lower limit temperature T4;
When (b) Teat pump boiler detects in real time, collect the temperature of outdoor environment temperature sensor T1 and water tank temperature sensor T2 by Temperature sampler;
(c) microprocessor receives the temperature of outdoor environment temperature sensor T1 that Temperature sampler collects and water tank temperature sensor T2 and according to the relational expression of built-in outdoor environment temperature-time function relation formula and the instantaneous heating capacity of Teat pump boiler and outdoor environment temperature, water tank actual temperature, calculates the opening time t2 of best Teat pump boiler automatically;
(d) arrive when calculating the best opening time t2, microprocessor output run signal, Teat pump boiler brings into operation;
(e) when water tank temperature arrived design temperature ceiling temperature T3, Teat pump boiler was out of service;
(f) after out of service, because water tank natural heat dissipation or when setting water use peak water causing water tank temperature to be reduced to water tank design temperature lower limit temperature T4 on a small quantity the time before, microprocessor output run signal is opened Teat pump boiler automatically, up to reaching water tank design temperature ceiling temperature T3;
(g) control mode can select artificial mode to intervene by input module at any time, elected with after the artificial mode, control system adopts the start-stop control mode, detect water tank temperature in real time, when water tank temperature arrives design temperature ceiling temperature T3, Teat pump boiler is out of service, and when water tank temperature was reduced to water tank design temperature lower limit temperature T4, Teat pump boiler (3) was opened.
Described input module is input keyboard or touch-screen.
The present invention compared with prior art has following advantage:
(1) Teat pump boiler can calculate optimum operation time period and startup automatically automatically according to set water temperature and water time, make Teat pump boiler in the highest time period operation of whole day efficiency, thereby energy-saving effect is better;
(2) control method of the present invention is simple and reliable, and is with low cost.
