Abstract

The utility model discloses an air cooled heat pump module unit program -controlled system, including warm program -controlled system, a PCL controller and a plurality of air cooled heat pump of the group unit module of leading to, the every air cooled heat pump of group unit module is established ties by a plurality of air cooled heat pump units and is constituted, a plurality of air cooled heat pump of group unit modules each other parallelly connected and all with PCL controller electric connection, the PCL controller with the warm program -controlled system electric connection that leads to, it constitutes a set of air cooled heat pump unit module to establish ties through a plurality of air cooled heat pump units, thereby through parallelly connected the connection with the PLC controller of a plurality of air cooled heat pump of group unit modules forming programme -controlled group control, come intelligent control respectively to organize the function of air cooled heat pump unit module according to the load height, under the low -load condition, the minimum load input power of every group unit declines to a great extent, owing to heat the efficiency promotion under the high load capacity condition, its energy consumption also declines to a great extent, can improve simultaneously heats efficiency.

Description

Air-cooled heat pump module unit stored program controlled

Technical field

The utility model relates to a kind of heat sink, particularly relates to a kind of air-cooled heat pump module unit stored program controlled.

Background technology

Due to existing Economic Evaluation requirement, the pressure of factory's electricity consumption is larger.Therefore the Energy Efficiency Ratio for the cooling and warming of heating ventilation air-conditioning system has more and more higher requirement.The air-cooled heat pump type of heating ventilation air-conditioning system many employings in the past screw water chiller-heater unit cooling and warming, the pattern that air-treatment unit carries out heat exchange carries out Operation system setting.

The adjustable range of existing its refrigerating capacity of air-cooled heat pump type screw water chiller-heater unit is 25% ~ 100%, separate unit input power 233kw, refrigerating capacity 630 ~ 650kw (180U.S.RT), heating capacity: 690kw, and global design is 2 standby with 1.The load adjustable extent of its run duration is less, and energy consumption is higher, and cooling and warming efficiency is lower.

Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of air-cooled heat pump module unit stored program controlled, make it have more value in industry.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide one can put forward reduction energy consumption, improves the air-cooled heat pump module unit stored program controlled of cooling and warming efficiency.

A kind of air-cooled heat pump module unit stored program controlled that the utility model proposes, it is characterized in that: comprise a HVAC stored program controlled, a PCL controller and some groups of Air-Cooled Heat Pump Unit modules, often organize Air-Cooled Heat Pump Unit module to be made up of some typhoon cold-heat pump units connected in series, described some groups of Air-Cooled Heat Pump Unit modules are parallel with one another and be all electrically connected with described PCL controller, and described PCL controller and described HVAC stored program controlled are electrically connected.

As further improvement of the utility model, described Air-Cooled Heat Pump Unit module is three groups, often organizes Air-Cooled Heat Pump Unit module and comprises three Air-Cooled Heat Pump Unit.

As further improvement of the utility model, the described maximum energy consumption often organizing Air-Cooled Heat Pump Unit module is 124.8kw per hour.

As further improvement of the utility model, the described maximum cooling capacity often organizing Air-Cooled Heat Pump Unit module is 390kw per hour.

As further improvement of the utility model, the described maximum heating capacity often organizing Air-Cooled Heat Pump Unit module is 426kw per hour.

By such scheme, the utility model at least has the following advantages: form one group of Air-Cooled Heat Pump Unit module by some typhoon cold-heat pump units connected in series, be connected by some groups of Air-Cooled Heat Pump Unit wired in parallel with PLC thus formed and control program control grouping, the running that Based Intelligent Control respectively organizes Air-Cooled Heat Pump Unit module is carried out according to load height, under low loading conditions, the minimum load input power often organizing unit declines to a great extent, due to cooling and warming improved efficiency under high-load condition, its energy consumption also declines to a great extent, and can improve cooling and warming efficiency simultaneously.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.

Embodiment: a kind of air-cooled heat pump module unit stored program controlled, comprise HVAC stored program controlled 1, PCL controller 2 and some groups of Air-Cooled Heat Pump Unit modules 3, often organize Air-Cooled Heat Pump Unit module in series by some Air-Cooled Heat Pump Unit 4, described some groups of Air-Cooled Heat Pump Unit modules are parallel with one another and be all electrically connected with described PCL controller, and described PCL controller and described HVAC stored program controlled are electrically connected.

Described Air-Cooled Heat Pump Unit module is three groups, often organizes Air-Cooled Heat Pump Unit module and comprises three Air-Cooled Heat Pump Unit.

The described maximum energy consumption often organizing Air-Cooled Heat Pump Unit module is 124.8kw per hour.

The described maximum cooling capacity often organizing Air-Cooled Heat Pump Unit module is 390kw per hour.
