Description
Technical field
The utility model belongs to refrigeration technology field, relates to a kind of air-conditioning.
Background technology
The development of modernization information technology, make the electronic equipment machine room universal day by day, electronic equipment has also proposed unprecedented high request to building environment, special air conditioning for device room is exactly the refrigeration plant that the running environment of constant temperature and humidity is provided for calculator room equipment, its design concept is big air quantity, little enthalpy difference, high sensible heat ratio.Generally, the overall refrigerating effect of air-conditioning comprises two parts, and a part is the sensible heat refrigerating capacity that is used to lower the temperature, and another part is the latent heat refrigerating capacity that is used to dehumidify.Sensible heat ratio is meant that the apparent cold of air-conditioning accounts for the ratio of overall refrigerating effect.Machine room is owing to good airproof performance, and personnel's rareness does not have the moisture source, and it is less therefore to remove humidity load.For sensible heat ratio is 0.9 refrigeration system, and the apparent cold that then is used to lower the temperature is 90% of an overall refrigerating effect, and the latent cold that is used to dehumidify simultaneously is 10% of an overall refrigerating effect.Even that is to say under the situation of, the demand that do not dehumidify qualified in the humidity that controls environment, still there is 10% refrigerating capacity to be used for dehumidifying, in order to keep the humidity in room, have to open simultaneously the electrode humidification function, consume very high electric energy.Therefore, the refrigerating capacity that in fact is used effectively only accounts for 80% of overall refrigerating effect.Under such operating mode, dehumidifying and the coefficient contradiction of humidification have not only caused the waste of refrigerating capacity, have also increased the consumption of electric energy.At present, Research on energy saving and exploitation mainly are divided into both direction in the refrigeration industry: concentrate on the optimal design of refrigeration system component on the one hand; Be new kind of refrigeration cycle and refrigeration system of structure on the other hand.The measure that improves sensible heat ratio mainly contains: 1, increase the fan delivery of evaporimeter, its shortcoming is that the blower fan power consumption can significantly increase, and the machine packet size needs corresponding increase; 2, increase heat exchange area, its shortcoming is that the heat exchanger size increases, and cost increases, and can't satisfy the demand of high heat, high humidity load condition; 3, reduce compressor capacity, its shortcoming is to satisfy high heat, the high humidity load demand to cold equally.
The utility model content
The technical problems to be solved in the utility model provides a kind of sensible heat that passes through the adjusting refrigeration air-conditioner simple and practical, good energy-conserving effect and recently realizes regulating working conditions, to reach the energy-saving type air conditioner of energy-saving effect.
The utility model solves above-mentioned technical problem by the following technical solutions: a kind of energy-saving type air conditioner, comprise compressor, condenser, evaporimeter, be provided with throttling arrangement at condensator outlet, between evaporimeter and compressor air suction mouth, be provided with pressure-regulating device or flow regulator.
Described pressure-regulating device or flow regulator are arranged on the outlet of evaporimeter.
Described pressure-regulating device is a pressure-control valve.
Described flow regulator is a flow control valve.
Described throttling arrangement is a heating power expansion valve.
Described throttling arrangement is an electric expansion valve.
Described throttling arrangement is a capillary.
The utility model changes the adjusting of the evaporating temperature realization sensible heat ratio of evaporimeter by throttling arrangement, pressure-regulating device or flow regulator.The utility model is having only the do not dehumidify operating mode of demand of refrigeration demand to be called dry cooling condition; There is existing refrigeration demand the operating mode of dehumidifying demand to be called wet cooling condition again.During dry cooling condition, required evaporating temperature is higher, then increases the aperture of throttling arrangement, reduces the aperture of pressure-regulating device or flow regulator simultaneously, improves the evaporator evaporation temperature, make this evaporating temperature near or a little more than the dew-point temperature of surrounding air.The refrigerating capacity of this moment all is used for cooling; During wet cooling condition, required evaporating temperature is lower, then reduces the aperture of throttling arrangement, increases pressure-regulating device or flow regulator aperture simultaneously, reduces the evaporator evaporation temperature, makes this evaporating temperature be lower than the dew-point temperature of surrounding air.The refrigerating capacity part of this moment is used for cooling, and a part is used for dehumidifying, just traditional air-conditioning system mode of operation.The utility model is simple in structure, only need to change the aperture of throttling arrangement, pressure-regulating device or flow regulator, just can effectively control the evaporating temperature of refrigeration working medium in evaporimeter, thereby the sensible heat ratio of control refrigeration system, the sensible heat ratio adjustable range is wide, and the regulating working conditions scope is wideer, has solved the dry cooling condition dehumidifying and the coefficient contradiction of humidification down of traditional air-conditioning system, reduced energy consumption, the annual operating cost about 30% of saving.
