Description
Technical field
The present invention relates to a kind of control method and water heater thereof of split Teat pump boiler, particularly relate to a kind of control method and water heater thereof of split fast heating type Teat pump boiler.
Background technology:
The Energy Saving Control of general Teat pump boiler is to adopt method for controlling timed power on/off; This is controlled at the high hot water temperature who keeps in the timed power on/off time period in the boiler; Do not guarantee the water temperature in the boiler outside time period at timed power on/off, possibly be cold water in the boiler.This control can be bigger the heat of reduction boiler scatter and disappear, can reach reasonable energy-saving effect.But the Along with people's growth in the living standard needs all to have at any time hot water, and the energy-saving effect of timed power on/off control is lost thereupon.
At present household heat pump water heater generally has two kinds of split type Teat pump boiler and circulating Teat pump boilers, and circulating Teat pump boiler is not by the circulation line of Teat pump boiler main frame, band water pump, form with the boiler and the controller of heat pump water heater of heat pump condenser; Split type Teat pump boiler is made up of the boiler and the controller of heat pump water heater of Teat pump boiler main frame, cold-producing medium tube connector, band heat pump condenser.Controller of heat pump water heater is furnished with hot water temperature's sensor, the start and stop of control Teat pump boiler main frame.These two types of ubiquitous problems of commercially available Teat pump boiler are that because the heating capacity of Teat pump boiler is generally less, heat production water is slow; Need accumulation of heat in the actual use; (be generally 100～600L), so heat-pump water-heater water tank configuration is all bigger so cause at first that difficult installation---modern architecture is skyscraper particularly, the general installing space of not reserving big capacity boiler; Cause difficult installation, can't use this energy-conserving product of Teat pump boiler; Next is that waste is serious---because water tank is big; Promptly enabling to install also generally is to be installed on balcony; Distant apart from the toilet, must bleed off the cold water among the hot water line waste that then can cause water resource during use, and can cause the waste of the energy hot water line's insulation that circulates; It three is that to produce water speed slow, and influence is used---need several hours as heating one case water in the winter time, after hot water uses, then also must wait for several hours; It four is to use inconvenience---and whether whether main frame, boiler etc. are all away from the toilet, have hot water, hot water enough etc. all unclear in the boiler.For circulating Teat pump boiler; Because recirculated water can not be at same position; In the process that hot water uses, can cause a large amount of hot and cold waters to mix inevitably; The available heat water capacity of water tank is reduced, cause the characteristics that effectively to utilize the low hot water temperature's high energy efficiency ratio of Teat pump boiler, cause the increase of system energy consumption.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art; A kind of control method and water heater thereof of split fast heating type Teat pump boiler are provided; The opening and closing of Based Intelligent Control water heater, and design a kind of split fast heating type Teat pump boiler thus, adopt the design of big Teat pump boiler main frame, little boiler; Teat pump boiler is installed as the common electrical water heater, with this solve difficult installation, water resource or the energy waste, produce water speed slow, use problems such as inconvenience.
In order to achieve the above object, the technical scheme of the present invention's employing is: a kind of control method of split fast heating type Teat pump boiler, this method comprise open operation method and shutoff operation method.

Xx is the concrete time instantly, and this moment, hour environment temperature was Tenxx, and initial 2min hourly detects and record environment temperature Ten, is labeled as a hour environment temperature Tenxx, and for example Ten08 is the temperature of 8:00 in morning, and be 8:00～8:02 detection time.
If the typical environment mean temperature be Tena then
Typical environment mean temperature Tena is the mean temperature of the environment of Ten20, Ten21, Ten22 every day in the formula, environment temperature when Ten20, Ten21, Ten22 are respectively 20:00 every day, 21:00,22:00, Tena for every day 22:03 calculate.
Split fast heating type Teat pump boiler calculates using water period t automatically:
Power on for the first time or during 14 days No Computed Datas of less than service time, be t with 6:00～8:00,17:00～23:00.
0:00～23:59 divided as T1 and in 2 minutes, lower the temperature >=4 ℃ the time every day, and writing down this time point is the water time point, if no longer detect the temperature drop of T1 in the 5min, no longer writes down the water time point, recording occurring continuously 14 days, and record is full, and after 14 days the earliest 1 day of automatic removing.
During record water time point, 00:00～5:00,5:00～11:00,11:00～16:00,16:00～00:00 totally 4 periods be will be divided into every day, Ti1, Ti2, Ti3, Ti4 will be designated as respectively.Time point was included in the period before the day part, and back time point is not included in the period.Using water period in period T1～T4 is denoted as t1～t4.
The calculating of using water period t1, N10 equals water time point quantity in the Ti1 period, and N10 calculates as follows before the 0:00 timesharing every day basis.T1 is not calculated in N10＜6 o'clock, N10 >=6 o'clock, and the step of calculating t1 is following:
(N10 * 80%+0.5), int representes to round for step 1, N1=int;
Step 3, get that earliest time point is the t1 starting point in the t11 period; When Tena＜20 ℃, push away 90min before time point; When 25 ℃＞Tena >=20 ℃, push away 40min before time point, when Tena >=25 ℃, push away 20min before time point, time point pusher 20min is the t1 terminal point the latest.
The method of calculating t2, t3, t4 is identical with the method for calculating t1.
