Description of drawings
Fig. 1 is the structure chart of the hot and cold water unit that provides of the utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of hot and cold water unit that the utility model provides, this hot and cold water unit is as shown in Figure 1, comprising: temperature sensor 10, hot and cold water group machine 11, water channel 12, backwater channel 13; Wherein this hot and cold water unit also comprises: gather the flowmeter 15 of refrigeration or heating capacity, the ammeter or the ammeter 18 of collection hot and cold water group machine 11 energy consumption parameters; Calculate Energy Efficiency Ratio (Coefficient Of Performance, COP) the control system 16 of range of operation and the control device 17 of control hot and cold water unit according to this ability parameter and this refrigeration or heating capacity in this COP range of operation operation;
Wherein, this flowmeter 15 is positioned at water channel 12, this flowmeter 15 and ammeter 18 respectively with control system 16, this control system 16 is connected with control device 17, control device 17 is positioned at hot and cold water group machine; This ammeter 18 also is connected with hot and cold water group machine 11.
The hot and cold water unit that the utility model provides has increased flowmeter, ammeter, control system and control device; So it can control the hot and cold water unit according to the refrigeration or the heating capacity of flowmeter survey; So it has the advantage of flexible control hot and cold water unit, in addition, because the hot and cold water unit that the utility model provides can let the hot and cold water unit always work in the COP range of operation; Improve power saving rate, had the high advantage of power saving rate.
Need to prove, above-mentioned control system 16 specifically can for: embedded Control plate, Programmable Logic Controller PLC or direct digital controller (direct digital control, DDC).
Need to prove that above-mentioned control device 17 specifically can be guiding valve, control valve, magnetic valve or stator etc.
Compressor with cooling-water machine is that example explains that this ability parameter and this refrigeration or heating capacity calculate the concrete mode of Energy Efficiency Ratio range of operation below,
After startup energy saving in running mode compression machine normally moves startup automatically; The control system selects control output signal kinds (analog signal, data signal, switching signal) to provide control signal regulating load rate according to control appliance kind (magnetic valve, guiding valve or stator etc.): as; When the load regulation mode is three sections magnetic valves adjustings; Load factor is respectively 25%, 50%, 75%, 100%; Control system correspondence provides control instruction respectively, calculates COP value and input database under every kind of load factor; When the load regulation mode is the electrodeless adjusting of analog signal; The control system increases progressively by 10% respectively and provides control instruction; As 10%, 20%, 30%-100%; The control system calculates COP value and input database according to every kind of load factor situation test electric energy with refrigerating capacity, by theory and practical data can know when load factor from little when being fully loaded with variation COP be changed to little size, the COP value was the highest when promptly load factor was about 60% (different type of machines differences).Data collection and analysis will take into full account the channel characteristic and the retardance of water system.
The user is provided with COP minimum operation parameter voluntarily; Be set to 4.0 like parameter; The COP maximum can know to be 5.5 (for example) from the system data library inquiry, and the system that promptly controls seeks output COP value automatically and controls control device more than or equal to the state energy adjustment mode under 4.0 situation according to parameter value is set.Unit will start the back in operation and under the situation of COP value more than or equal to this minimum setting value, move automatically; Be that unit will move between 4.0-5.5 in the COP value; The unloading manner that adds of unit still adopts temperature or cold control mode, as control adds unloading according to supply and return water temperature, when water temperature is higher than setting value, loads; Off-load when water temperature is lower than setting value can only be in the COP range of set value but add the off-load scope.COP minimum operation parameter value also can not be provided with too high, and the setting of this value is please carried out in system's allowable error scope, and setting value is high more, and power saving rate increases, and the water temperature control accuracy reduces.
Unit will (being between the COP range of operation) move between COP setting value and COP maximum under this energy saver mode, avoid the energy dissipation of COP low spot, and the economize on electricity space is huge.
