Background
In some specific workplaces, in order to meet specific process conditions, the temperature and humidity of the environment must be stabilized within a certain range, and at this time, a constant-temperature constant-humidity air conditioning unit needs to be installed in the workplace. The air conditioning unit has the following functions: when the indoor temperature is lower than the set temperature range, the unit needs to operate to heat and heat the room; when the indoor temperature is higher than the set temperature range, the unit needs to run for refrigeration to cool the room; when the humidity is lower than the humidity setting range, the humidifier needs to work to humidify the room; when the humidity is higher than the humidity setting range, the unit needs to perform dehumidification operation on the room. By the above regulation of the air conditioner, the indoor temperature and humidity are maintained within the required range to meet the working requirement.
When the existing constant-temperature and constant-humidity air conditioning system operates in a dehumidification mode, the temperature of a room is often reduced, if the temperature of the room is lower than a set temperature range and the humidity does not meet a set requirement, electric heating needs to be started to raise the temperature of the room, and at the moment, a compressor still normally operates to refrigerate and is used for dehumidification. Therefore, the unit refrigeration and the electric heating can work simultaneously, and the running cost is extremely high.

Detailed Description
The principles and features of the present invention are described below in conjunction with the accompanying fig. 1, which is provided by way of example only to illustrate the present invention and not to limit the scope of the present invention.
A novel energy-saving constant-temperature and constant-humidity unit comprises a gas-liquid separator 1, a compressor 2, an outdoor condensing unit 3, an indoor evaporator 4, a reheating condenser 5, a straight-through electromagnetic valve 6 and a reheating electromagnetic valve 7. The gas-liquid separator 1, the compressor 2, the outdoor condensing unit 3, the straight-through electromagnetic valve 6 and the indoor evaporator 4 are sequentially connected in series to form a loop, the reheating electromagnetic valve 7 is connected with the reheating condenser 5 in series, and the reheating electromagnetic valve 7 is connected with the reheating condenser 5 in series and then connected with the straight-through electromagnetic valve 6 in parallel. The direct solenoid valve 6 and the reheating solenoid valve 7 are selectively opened, when the direct solenoid valve 6 is opened and the reheating solenoid valve 7 is closed, the reheating condenser 5 does not work, and a medium in a loop enters the indoor evaporator 4 after passing through the outdoor condensing unit 3; when the straight-through electromagnetic valve 6 is closed and the reheating electromagnetic valve 7 is opened, the medium in the loop passes through the outdoor condensing unit 3, the reheating condenser 5 and the indoor evaporator 4 in sequence.
In order to ensure that the loop keeps a better working state, a low-pressure switch 8 is connected on the loop between the gas-liquid separator 1 and the compressor 2; a high-voltage switch 9 is connected on a loop between the compressor 2 and the outdoor condensing unit 3; and a loop between the straight-through electromagnetic valve 6 and the indoor evaporator 4 is sequentially connected with a filter 10 and a thermostatic expansion valve 11. The outdoor condensing unit 3 is provided with an independent speed-adjusting fan 12, and the reheat condenser 5 and the indoor evaporator 4 are provided with a common air supply fan 13. Through adjusting the rotational speed of speed governing fan 12, realize adjusting the heat dissipation capacity of outdoor condensation unit 3, and then the heat dissipation capacity of accurate regulation reheat condenser 5 reaches the effect of accurate accuse temperature.
The working principle of the utility model is as follows: when the whole equipment runs in summer, the unit needs to run for refrigeration and dehumidification due to high temperature and humidity. At this time, the temperature reduction and the dehumidification are simultaneously carried out, the air is cooled by using the low temperature on the surface of the indoor evaporator 4, and part of vapor in the air is condensed into liquid water to be discharged. When the indoor temperature and the indoor humidity are both higher than the set temperature, the direct electromagnetic valve 6 is opened, and the reheating electromagnetic valve 7 is closed; at this time, the medium is cooled by condensation of the outdoor condensing unit 3, throttled by the thermostatic expansion valve 11, and enters the indoor evaporator 4 for evaporation and cooling. At the moment, the heat is completely discharged to the outside through the outdoor condensing unit 3, and a complete air conditioner cooling and dehumidifying cycle is formed.
When the temperature is lower than the set lower temperature limit and the humidity does not reach the set humidity, the straight-through electromagnetic valve 6 is closed, and the reheating electromagnetic valve 7 is opened. At this time, the medium passes through the outdoor condensing unit 3, enters the reheat condenser 5, is throttled by the thermostatic expansion valve 11, and enters the indoor evaporator 4 for evaporation and temperature reduction. Meanwhile, the outdoor condensing unit 3 carries out frequency conversion adjustment according to the indoor temperature, and the heat dissipation capacity is adjusted through adjusting the rotating speed of the speed adjusting fan 12 of the outdoor condensing unit 3 through frequency conversion, so that the heat dissipation capacity of the reheating condenser 5 is adjusted, the supercooled air is properly heated, and the indoor temperature is maintained within a required range.
When the unit is in the dehumidification and cooling working condition, the added reheat condenser 5 is utilized, the supercooled air is accurately heated by adjusting the heat dissipation capacity of the outdoor condensing unit 3, and the electric heating power is completely replaced under the condition that the energy consumption of the compressor 2 is unchanged. Therefore, the energy consumption of the unit under the working condition is greatly reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
