Summary of the invention
Task of the present utility model is to provide a kind of waterpower bleeder mechanism with heat accumulation function, in place of composition heating system supporting with net for air-source heat pump units can be efficiently against the deficiencies in the prior art.
Technical scheme is as follows:
This utility model is made up of accumulation of heat tank body, circulating pump, secondary cycle pump, temperature controller and electronic bypass regulator valve.Primary circuit water inlet pipe and primary circuit outlet pipe on accumulation of heat tank body are connected with the outlet of source pump and the water sucking mouth of a circulating pump respectively, and secondary circuit outlet pipe and secondary circuit water inlet pipe on accumulation of heat tank body are connected (as shown in Figure 1) with the water sucking mouth of secondary cycle pump and the return pipe of indoor heating system respectively.The heat that net for air-source heat pump units produces is transported in heat-accumulator tank by primary circuit, heat in heat-accumulator tank is transported in indoor heating system by secondary circuit, when outside air temperature raises, net for air-source heat pump units is stored in heat-accumulator tank because of the heat that heat supply quantitative change greatly and additionally produces, and the frequent start-stop thus avoiding unit improves the stability of heating and the service life of unit.
The heat that the amount of stored heat of this utility model heat-accumulator tank produces in 10 minutes under standard condition more than net for air-source heat pump units, it is possible not only to reduce the start-stop frequency of unit and can also continue when unit defrosting to provide heat to indoor heating system.
It is provided with electronic bypass regulator valve between secondary circuit inlet tube and outlet tube of the present utility model, when there is fluctuation in the water temperature in heat-accumulator tank, after the leaving water temperature detected is compared by temperature controller with setting value, control electronic bypass regulator valve opens and closes the leaving water temperature with constant secondary circuit.Above-mentioned temperature controller compensates function with outside air temperature, and the leaving water temperature value of secondary circuit is automatically set according to outside air temperature by it.
This utility model compared with prior art has the following advantages that and salience effect: the heat accumulation function of this device solves source pump heating load and do not mates, with heating system thermic load, the problem caused；Source pump intermittent duty and defrosting do not affect the normal heat supply of secondary circuit；Source pump can be run in the paddy electricity period at night, by the heat storage that produces in tank body for peak electricity period, the economy that raising heats.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
The heat that primary circuit is responsible for that net for air-source heat pump units 14 is produced in this utility model is transported in accumulation of heat tank body 1, and secondary circuit is responsible for the heat in accumulation of heat tank body 1 to be transported to heating system 15, and two closed circuits run independently of one another.Primary circuit can also be made up of several independent loops, and each loop connects from different net for air-source heat pump units respectively；The supply water temperature of secondary circuit is automatically set according to outside air temperature by temperature controller 5, and different outside air temperatures uses different supply water temperatures.
When outside air temperature calculating temperature outdoor equal to or less than heating, the leaving water temperature (supply water temperature of heating system) of secondary circuit is identical with the leaving water temperature that source pump 14 sets (such as 40 DEG C), electronic bypass mediation valve 4 is closed, the heat that source pump 14 produces all is transported to indoor heating system 15 (shown in Fig. 2), and now accumulation of heat tank body 1 not accumulation of heat is in direct heating state.
When outside air temperature calculating temperature outdoor higher than heating, temperature controller 5 resets supply water temperature (less than 40 DEG C), and electronic bypass mediation valve 4 is opened, and flow is G2Backwater through bypass valve with from accumulation of heat tank body 1 flow out flow be G3(G3=G1-G2) hot water mixing, make supply water temperature constant to new setting value.Owing to flowing in and out the flow G of accumulation of heat tank body 1 through water inlet pipe 9 and outlet pipe 83Flow G less than primary circuit1, partial discharge is G2Primary circuit hot water flowed to outlet pipe 7 by water inlet pipe 6, the heat that this part hot water carries just is stored in accumulation of heat tank body 1 (shown in Fig. 3), and now accumulation of heat tank body 1 is in the state of limit accumulation of heat limit heat supply.
When the leaving water temperature of primary circuit reaches setting value (such as 38 DEG C), net for air-source heat pump units 14 and a circulating pump 2 are by complete for accumulation of heat tank body 1 out of service accumulation of heat, heat needed for heating system is all from the heat (shown in Fig. 4) stored in tank body 1, and now accumulation of heat tank body 1 is in single heat release state.Night paddy electricity period temperature controller 5 automatically by the water outlet temperature setting of net for air-source heat pump units 14 to 55 DEG C; return water temperature when source pump 14 is shut down is set to 53 DEG C; so accumulation of heat tank body 1 can store the heat that more paddy electricity period produces, and improves the economy of heat pump heating.
Three kinds of states in above-mentioned heat-accumulator tank can occur alternate along with the change of outside air temperature and the different of unit working method, thus completes the task of carrying out heat supporting with net for air-source heat pump units.
