Description
Technical Field
The utility model relates to a frostless computer lab technical field, concretely relates to outdoor frostless computer lab based on air dehumidification.
Background
The heat source pump is an energy-saving device which utilizes high-level energy to enable heat to flow from a low-level heat source to a high-level heat source, namely, low-level heat energy which cannot be directly utilized, such as air, soil and heat contained in water, can be converted into high-level heat energy which can be utilized, and therefore the purpose of saving part of high-level energy, such as coal, gas, oil, electric energy and the like, is achieved. The air heat source pump is one kind of heat source pump, and it uses air as the low level heat source of the heat source pump, and it is inexhaustible. Has the advantages of integrated cold and heat sources, no cooling water consumption, no need of arranging a corresponding boiler fuel supply system and the like.
In winter, the air heat source pump is in the operating state of heating working condition. The air heat source pump is usually installed outdoors, the minimum temperature t requirement for safe and reliable operation is-15 ℃, and when the temperature is lower than the minimum temperature t requirement, the energy efficiency ratio of the air heat source pump is rapidly reduced. And the highest humidity RH requirement of the safe and reliable operation of the air heat source pump is 65%, and when the humidity is higher than the value, the heat exchange fins of the air heat source pump are easy to frost. The gaps among the heat exchange fins are easily blocked due to the excessively thick frost layer, the heat exchange performance of the heat exchange fins is reduced, the heat supply effect is reduced, and the machine can be stopped when the heat exchange fins are serious.
Currently, there are two main methods for air conditioner defrosting: one is stopping defrosting, namely, the air conditioner is converted from heating to refrigerating, and the high-temperature and high-pressure refrigerant output by the compressor is conveyed to a frosted heat exchanger of the outdoor unit by converting the flow direction of the refrigerant, so that a frost layer on a heat exchange fin of the outdoor unit is melted. The other method is defrosting without stopping, namely, part of high-temperature and high-pressure refrigerant gas output from the compressor flows back to a heat exchanger of the outdoor unit, so that the temperature of the heat exchanger rises continuously to melt frost layers on heat exchange fins of the outdoor unit. Both of the above two ways are defrosting after the heat exchange fins are frosted.

The air heat source pump 2 is installed in the machine room 1, and the air pump 3 and the dehumidifier 4 are both installed outside the machine room 1. The air pump 3 pressurizes air with high humidity, then the air is introduced into the dehumidifier 4 through the first air pipe, and the air is dehumidified by the dehumidifier 4 and then finally enters the machine room 1 through the second air pipe. The air in the machine room 1 is ensured to be dry, and the heat exchange fins of the air heat source pump 2 are not easy to frost. The air outlet of the air heat source pump 2 is communicated with an exhaust pipe 5 arranged on the machine room 1, and the air exhausted from the air heat source pump 2 is exhausted to the atmosphere through the exhaust pipe 5.
The air heat source pumps 2 are provided in number and form an air heat source pump group. The air pump 3 is integrated with an air volume regulating valve, so that the control of the air intake volume can be realized.
No matter whether the humidity value and the temperature value of the outdoor air reach the dehumidification degree, the outdoor air can pass through the air pump 3 and the dehumidifier 4 and then enter the machine room 1. However, when the RH of the outdoor air is < 67% or t > 5.8C, the air introduced into the room 1 does not need to be dehumidified. In order to avoid wasting electric energy and realize natural ventilation of the machine room 1, the machine room preferably further comprises a window 6, a mounting window is formed in a side wall of the machine room 1, and the window 6 is mounted in the mounting window. When the RH of the outdoor air is more than or equal to 67 percent and t is more than or equal to-12.8 ℃ and less than or equal to 5.8 ℃, the window 6 is closed, the air pump 3 and the dehumidifier 4 are opened, and the outdoor wet and cold air is prevented from entering the machine room 1. When the RH of the outdoor air is less than 67 percent or t is more than 5.8 ℃, the window 6 is opened, the air pump 3 and the dehumidifier 4 are closed, the outdoor air freely enters the machine room 1, and the heat exchange fins of the air heat source pump 2 are not easy to frost because the air entering the machine room 1 does not meet the frosting condition.

When the humidity RH of the outdoor air reaches a preset trigger value, such as RH is larger than or equal to 67%, a transmitter integrated by the hygrometer sends a humidity trigger signal to the controller 7; the temperature t reaches a preset trigger value, for example, t is more than or equal to-12.8 ℃ and less than or equal to 5.8 ℃, and a transmitter integrated with the thermometer sends a temperature trigger signal to the controller 7. After receiving the temperature trigger signal and the humidity trigger signal at the same time, the controller 7 sends a first working signal to the air pump 3, and the air pump 3 works; sending a second working signal to the dehumidifier 4, and enabling the dehumidifier 4 to work; and sending a closing signal to the electric window, and closing the electric window. When the humidity RH of the outdoor air is less than 67%, the transmitter integrated with the hygrometer sends a first interrupt signal to the controller 7; at a temperature t > 5.8 deg.c, the transmitter of the thermometer integrated arrangement sends a second interrupt signal to the controller 7. After receiving the first interrupt signal or the second interrupt signal, the controller 7 sends a first stop signal to the air pump 3, and the air pump 3 stops working; sending a second stop signal to the dehumidifier 4, and stopping the dehumidifier 4; and sending an opening signal to the electric window, and opening the electric window.
Preferably, the thermometer is integrated with the hygrometer and forms a thermo-hygrometer. As a prior art, the thermo-hygrometer detects the humidity and temperature of the air in real time and sends a total trigger signal to the controller 7 through its integrally arranged transmitter. When the humidity RH of the outdoor air is more than or equal to 67% and the temperature t is more than or equal to minus 12.8 ℃ and less than or equal to 5.8 ℃, the hygrothermograph sends a total trigger signal to the controller 7, and the controller 7 controls the air pump 3 and the dehumidifier 4 to work and controls the electric window to be closed after receiving the total trigger signal. When the air humidity RH is less than 67% or the temperature t is more than 5.8 ℃, the controller 7 controls the air 3 and the dehumidifier 4 to stop working and controls the electric window to open.
In order to improve the dehumidification effect, it is preferable that the air pump 3 is connected with the dehumidifier 4 to form a dehumidification unit, and the dehumidification unit is provided with a plurality of dehumidification units. A plurality of dehumidification units work simultaneously, and the dehumidification effect is good.
Preferably, the dehumidifier 4 is a membrane dehumidifier. The membrane type dehumidifier mainly uses the pressure difference of water vapor on two sides of a membrane as a driving force, and utilizes the selective permeability of the membrane material to the water vapor to separate the water vapor from other gases so as to achieve the aim of dehumidifying the gases. The membrane process dehumidification can reduce the relative humidity of the air to a very low level, so that the phase change driving potential is very low and frosting cannot be carried out.
