The utility model discloses an energy-saving device for controlling heating and cooling of a central air conditioner. The device comprises a compressor, a condenser, an evaporator, fresh air units, fan coil units, a throttling valve, a unit controller, a heating and cooling controller, an indoor temperature sensor and an outdoor temperature sensor, wherein an air outlet of the compressor is connected with an air inlet of the condenser through a pipeline; a liquid outlet of the condenser is connected with groups of fresh air units and the fan coil units; liquid outlets of the fresh air units and the fan coil units are connected with the evaporator through the throttling valve; an air outlet of the evaporator is connected with an air inlet of the compressor. When environmental temperature or the tail load of the air conditioner is changed, the temperature of a cooling water outlet and a cooling water inlet of a main unit of the central air conditioner is changed, and the efficiency of the main unit is also changed, so that the main unit of the central air conditioner can run under optimal conversion efficiency at any time, and the aim of saving energy is fulfilled. Related parameters measured during actual running show that energy can be saved by about 35 percent compared with that consumed by a conventional central air conditioning unit and remarkable economic benefits are created.
Description
Technical field
The utility model relates to a kind of central air-conditioning refrigeration plant control technology field, especially relates to the hot and cold two temperature regulation and control energy savers of a kind of central air-conditioning.
Background technology
Central air-conditioning is that megastore, pharmaceutical factory, the conventional of intelligent building building mansion establish each.It can improve people's work and living environment.Improve people's life and the general level of the health, but central air-conditioning is also the equipment of energy consumption maximum in building.Existing central air conditioning plant is realized refrigeration the heat in room must be discharged to atmosphere when freezing summer in, and the heat in atmosphere must be mentioned in room while heating in the winter time, realize and heating.But, when summer environment temperature is very high, to heat release in atmosphere or when environment temperature is very low in the winter time, from atmosphere, absorb heat, the effect that all needs aircondition work long time just can reach refrigeration or heat, therefore the energy consumption of existing central air-conditioning is sizable.
In prior art, take handpiece Water Chilling Units as example, general employing manual mode is a certain steady state value (being for example 7 ℃) by chilled water water outlet temperature setting, this is demand while generally believing that due to this area chilled water leaving water temperature can meet air-conditioning peak load (Design cooling load) 7 ℃ time substantially, and the air conditioner load of actual building is in most of the time operation under sub-load (non-peak load), during this, can meet by suitable raising chilled water leaving water temperature the demand of air conditioner load.According to statistics, the energy consumption of central air-conditioning has accounted for 50% left and right of building energy consumption.Existing central air conditioner system still adopts easy control appliance mostly, does not possess intelligent control function, can not automatically regulate chilled water flow according to end load variations, causes mass energy waste.
Summary of the invention
The utility model object is to provide the hot and cold two temperature regulation and control energy savers of a kind of central air-conditioning.To solve, the existing energy consumption of prior art is large, the wasting of resources is large, production cost is compared with high-technology problem.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the hot and cold two temperature regulation and control energy savers of central air-conditioning, comprise compressor, condenser, evaporimeter, new blower fan group, fan coil, choke valve, generator set controller, two temperature modulator, indoor temperature transmitter, outdoor temperature sensor; The gas outlet of described compressor is connected with the air inlet of condenser by pipeline, and the liquid outlet of this condenser is connected with fan coil with the new blower fan group of many groups, and the liquid outlet of new blower fan group and fan coil is connected with evaporimeter by choke valve; The gas outlet of evaporimeter is connected with the air inlet of compressor; The defeated input that is connected to two warm modulators of temperature signal output of described indoor temperature transmitter and outdoor temperature sensor, the defeated input that is connected to generator set controller of regulating command output of this pair of warm self adaptation modulator.
As preferably, the output of described generator set controller connects respectively the control input end of condenser temperature controller, evaporator temperature controller and compressor.
As preferably, the output of described condenser is provided with temperature sensor, and the output of this temperature sensor is connected with cooling tower, and the cooling fluid in this cooling tower is back in condenser by coolant pump.
The utlity model has that energy consumption is little, production cost is low, greatly saved the advantages such as resource.For handpiece Water Chilling Units, unit overwhelming majority run duration chilled water is set the leaving water temperature that leaving water temperature is set higher than conventional central air-conditioning unit; For the air conditioner refrigerating unit of direct evaporation cooling, at most run durations, the evaporating temperature of its setting is higher than the evaporating temperature of conventional air-conditioning.When environment temperature or air conditioning terminal load changes, the cooling water entry and exit temperature of central air conditioner main machine will change thereupon, and main frame efficiency also changes thereupon.Thereby guarantee that central air conditioner main machine moves at any time under optimal conversion efficiency, make cooling water pump move lower than under rated load through being everlasting simultaneously, realize water pump and main frame power-saving running, reach energy-conservation object.Through actual motion, record relevant parameter and show, energy-conservation 35% left and right of the more conventional central air-conditioning unit of the utility model, remarkable in economical benefits.
