Abstract

The utility model relates to a fresh air air conditioner with a two-stage surface cooler. The utility model aims at resolving the technical problems of big energy consumption and low efficiency existing in the prior fresh air air conditioner and providing the fresh air air conditioner with the two-stage surface cooler, which is high-efficiency and energy-saving. The fresh air air conditioner with the two-stage surface cooler comprises a surface cooler and a fan, wherein the surface cooler comprises a first-stage surface cooler and a second-stage surface cooler which are connected in series; the first-stage surface cooler is provided with a coolant inlet and a fresh air outlet; the second-stage surface cooler is provided with a coolant outlet and a fresh air inlet; fresh air and coolant reversely contact on the first-stage surface cooler and the second-stage surface cooler for exchanging heat. For the sake of optimization, a filter screen is arranged on the front of the fresh air inlet. The fresh air air conditioner utilizes the reverse flow of air and the coolant, thereby widening the temperature difference and the enthalpy difference between both sides of the air and the coolant and improving the heat exchange efficiency; and the fresh air air conditioner is particular applied to radiation air conditioning systems.

Description

Fresh air processor with twin-stage surface cooler
Technical field
The utility model relates to a kind of fresh air processor with twin-stage surface cooler.
Background technology
Fresh air conditioner machine at present both at home and abroad commonly used adopts surface cooler and the new air heat-exchange of row more than one, needs bigger cold medium flux, the refrigerant of lower temperature, energy consumption greatly, summer dehumidification rate low.
The utility model content
The technical problems to be solved in the utility model is how to overcome big, the inefficient defective of existing fresh air conditioner function consumption, provides a kind of efficient, energy-conservation, has the fresh air processor of twin-stage surface cooler.
For solving the problems of the technologies described above, originally have the fresh air processor of twin-stage surface cooler, comprise surface cooler and blower fan, described surface cooler comprises the I level surface cooler and the II level surface cooler of mutual series connection, I level surface cooler is provided with refrigerant import and new wind outlet; II level surface cooler is provided with refrigerant exit and fresh inlet, new wind, refrigerant reverse contact heat-exchanging on I level, II level surface cooler.So design, energy-conservation, efficient, the new wind-warm syndrome degree of generation can be also lower than the refrigerant temperature after the heat exchange.In other words, higher refrigerant temperature just can be controlled at new wind on the suitable temperature.
As optimization, be provided with screen pack before the described fresh inlet.So design, the new wind dust that produces is few on the one hand, quality good, on the other hand, can not accumulate too much dust on the surface cooler, influences heat exchange efficiency.
The utility model is divided into I, II two-stage with surface cooler, and the low temperature refrigerant is introduced into II level surface cooler, will supply with I level surface cooler at the medium temperature refrigerant that II level surface cooler heats up by the wet exchange of heat and use.The new wind of outdoor high temperature high humidity carries out heat exchange with I level surface cooler earlier, and new wind has reduced temperature and improved relative humidity, carries out the wet exchange of heat with the water at low temperature of II level surface cooler again, reaches target dew point temperature.
The utility model utilizes air and refrigerant reverse flow, has strengthened the temperature difference and the enthalpy difference of refrigerant and air sides.Improved heat exchanger effectiveness,, can improve the refrigerant temperature of new blower fan, also improved the evaporating pressure of system, saved the energy owing to adopted the processing method of twin-stage surface cooler.Particularly, can under the prerequisite that does not reduce environment temperature, reduce the air water capacity at transition season.Save the energy, improved comfort level, be specially adapted to air-conditioning system.
Description of drawings
Below in conjunction with accompanying drawing the fresh air processor that originally has the twin-stage surface cooler is described further:
Fig. 1 is the structural representation that originally has the fresh air processor of twin-stage surface cooler.
Among the figure: 1 is that I level surface cooler, 2 is that II level surface cooler, 3 is that refrigerant import, 4 is that refrigerant exit, 5 is that new wind outlet, 6 is that fresh inlet, 7 is that screen pack, 8 is that blower fan, 9 is a refrigerant circulation duct between I, the II level surface cooler.
The specific embodiment
Embodiment one: as shown in Figure 1, the fresh air processor that originally has the twin-stage surface cooler comprises surface cooler and blower fan 8, and wherein said surface cooler comprises the I level surface cooler 1 and the II level surface cooler 2 of mutual series connection, and I level surface cooler 1 is provided with refrigerant import 3 and new wind outlet 5; II level surface cooler 2 is provided with refrigerant exit 4 and fresh inlet 6, new wind, refrigerant reverse contact heat-exchanging on I level, II level surface cooler.Also be provided with screen pack 7 before the described fresh inlet 6.
For the direct-cooling type air-conditioning, described refrigerant can be compressible refrigerants such as fluorine Lyons.Described surface cooler is evaporimeter, forms heat pump with blower fan, condenser, expansion valve and compressor etc.
For the indirect-cooling air-conditioning, described refrigerant is the indirect heat exchange medium, can be water or antifreeze water, and described surface cooler is heat exchanger, needs to be equipped with evaporimeter in addition, and this evaporimeter and blower fan, condenser, expansion valve and compressor etc. are formed heat pump.Utilizing this heat pump for water or antifreeze water heat exchange, is new air heat-exchange by water or antifreeze water.
Certainly, described refrigerant can also be underground water or other low-temperature receivers.
Below only be at three kinds of different refrigerants for example, protection domain of the present utility model be not limited to above-mentioned for example, any according to the scheme that above-mentioned mentality of designing proposed, all in its protection domain.
