Technical field
The utility model relates to central air conditioner system, relates in particular to a kind of source, many tablelands heat pump main frame automatic start-stop control system that is used for central air conditioner system.
Background technology
See also Fig. 1, structural representation for source, the many tablelands heat pump engine control system of existing central air conditioner system, comprise several earth source heat pump main frames 1 ' that are connected in parallel on terminal load side equipment 2 ' two ends, an and water circulating pump 3 ' of connecting with terminal load side equipment 2 ', operated by rotary motion refrigeration supply water temperature is 7 ℃ in the central air conditioner system, through return water temperature after the terminal load side equipment 2 ' cold scattering is 12 ℃, for earth source heat pump main frame 1 ', intake 12 ℃, 7 ℃ of water outlets are used for terminal load side equipment 2 ' behind the refrigeration cool-down.When the air conditioner load reduction, the cold that terminal load side equipment 2 ' needs reduces, and return water temperature can progressively reduce, and need manually turn off the part main frame this moment, avoids energy waste; When the air conditioner load rising, the cold that terminal load side equipment 2 ' needs increases, and return water temperature raises, and need manually restart earth source heat pump main frame 1 ' this moment, the result of use of assurance air-conditioning system.This control system needs personnel often to observe return water temperature, according to temperature start and stop air-conditioner host.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and source, a kind of many tablelands heat pump main frame automatic start-stop control system is provided, it can realize automatic start-stop, have convenient, the accurate advantage of control, can also energy savings in the comfortableness that guarantees air-conditioning system.
The technical scheme that realizes above-mentioned purpose is: source, a kind of many tablelands heat pump main frame automatic start-stop control system, comprise terminal load side equipment and several and described terminal load side equipment earth source heat pump main frame in parallel, an and water circulating pump that is series between terminal load side equipment and the earth source heat pump main frame, described each earth source heat pump main frame all receives from the current of terminal load side equipment output by described water circulating pump, treatedly return to described terminal load side equipment again, wherein, also be provided with a temperature control equipment on each earth source heat pump main frame, and the input of each earth source heat pump main frame also is in series with a temp probe that links to each other with described temperature control equipment.
The beneficial effects of the utility model are: the utility model is by setting up the loop temperature that temp probe detects each earth source heat pump main frame input; come shutdown temperature is provided with by the temperature control equipment of setting up; the utility model utilizes the air-conditioning return water temperature to control the start and stop of earth source heat pump main frame automatically; do not need personnel to observe; the earth source heat pump main frame can be realized automatic start-stop, and control is convenient, accurate.Can also energy savings when guaranteeing the comfortableness of air-conditioning system.
Description of drawings
Fig. 1 is the structural representation of source, the many tablelands heat pump engine control system of prior art;
Fig. 2 is the structural representation of source, many tablelands of the present utility model heat pump main frame automatic start-stop control system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
See also Fig. 2, there is shown source, a kind of many tablelands of the present utility model heat pump main frame automatic start-stop control system, comprise the earth source heat pump main frame 2 that terminal load side equipment 1 and several and terminal load side equipment 1 are in parallel, an and water circulating pump 3 that is series between terminal load side equipment 1 and the earth source heat pump main frame 2, each earth source heat pump main frame 2 all receives from the current of terminal load side equipment 1 output by water circulating pump 3, treatedly return to terminal load side equipment 1 again, also be provided with a temperature control equipment 4 on each earth source heat pump main frame 2, and the input of each earth source heat pump main frame 2 also is in series with a temp probe 5 that links to each other with temperature control equipment 4.
In the utility model, temperature signal is passed to the start and stop that temperature control equipment 4 is controlled the earth source heat pump main frame, each source, tableland heat pump main frame 2 can independently be provided with the start and stop temperature, when return water temperature reaches the setting lower limit, shuts down by temperature control equipment 4 control earth source heat pump main frames 2; When return water temperature reaches capping, earth source heat pump main frame 2 restarts.Temperature control equipment 4 in the present embodiment adopts existing general equipment all can realize.
In the present embodiment, four earth source heat pump main frames 2 are arranged, shutdown temperature is set to 11 ℃, 10 ℃, 9 ℃, 8 ℃ respectively from left to right.When terminal load side equipment 1 reduces, return water temperature is reduced to 11 ℃, and the earth source heat pump main frame 2 that then is set to 11 ℃ is shut down; When terminal load side equipment 1 further reduces, return water temperature is reduced to 10 ℃, and the earth source heat pump main frame 2 that then is set to 10 ℃ is also shut down.Along with return water temperature progressively reduces, earth source heat pump main frame 2 cuts out by platform, until whole shutdown.
The turn-on temperature of each earth source heat pump main frame 2 is set to 13 ℃, 12 ℃, 11 ℃, 10 ℃ respectively.When terminal load side equipment 1 increases, when return water temperature is increased to 10 ℃, then be set to 10 ℃ earth source heat pump main frame 2 startups; When terminal load side equipment 1 further increases, when return water temperature is increased to 11 ℃, be set to 11 ℃ earth source heat pump main frame 2 startups.Along with return water temperature progressively raises, earth source heat pump main frame 2 starts by platform, until whole startups.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
