Description
Technical field
The present invention relates to dehumidifier fields, and in particular to a kind of multistage cold source swimming pool heat pump dehumidifier and its working method.
Background technique
With the continuous improvement of people's living standards, people do not require nothing more than the place that can be swum, to the environment of swimming
More stringent requirements are proposed, also needs to guarantee certain fresh-air ventilation amount, therefore, indoor pool Temperature and Humidity Control is increasingly by wide
General attention.When relative humidity is excessively high, indoor air quality be cannot be guaranteed；When relative humidity is too low, water evaporation is too fast
It undoubtedly will increase input cost.In short, the quality requirements of air are higher and higher in the Room of pond, the function of swimming pool dehumidifier also requires to get over
Come more.Swimming pool dehumidifier uses on a large scale, and energy conservation also becomes the emphasis of concern
High-quality Swimming pool, not only need it is annual keep pond water temperature, pond Room air themperature, relative humidity it is constant, also want
Guarantee that the enough supply amounts of fresh air, fresh air can be used for meeting human health demand, foul indoor air can be discharged, eradicates different
Taste guarantees the fresh comfortable of air.For swimming pool, substantially it is considered that the hot humidity load of water bring is invariable, but
It is to supplement the load of fresh air to be changed at random according to outer work condition, the increasing of fresh air volume, summer high temperature high humidity or winter low temperature low humidity
Air can be very big to unit increase load, bring difficulty to even deviate from out demand model the control of Temperature and Relative Humidity of Indoor Air
It encloses.The air of indoor temperature and humidity relative comfort is exhausted directly to outdoor simultaneously, will cause the waste of the energy.If can be in the spring and summer autumn
Under winter various operating conditions, indoor environment stable conditions were not only guaranteed, but also have been able to satisfy the demand of fresh air volume, while can be by the energy of air draft not
Waste, moreover it is possible to not increase unit load, become the problem for needing to solve.
Simultaneously general swimming pool dehumidifier in order to avoid indoor air temperature it is excessively high, can swim with configuration air-conditioner outdoor unit
Pond is generally located on large-scale building and activity centre etc., these activity centres are normally at bustling central area, external zones
Domain space an inch of land is an inch of gold, periphery greening and arrangement are required to very high, it is clear that and the installation of outdoor unit and arrangement are a very big problems,
One installation for carrying out outdoor unit can destroy the aesthetic feeling entirely planned, two carry out the high temperature air of outdoor unit discharge to surrounding greening and road
It will impact.Outdoor unit is mounted on skyscraper roof, thus the host of dehumidifier and outdoor unit distance by some places
Several floors can be passed through, cause indoor and outdoor machine pipeline length, height difference big, the refrigerating capacity of unit is decreased obviously, and oil return is poor, complete machine efficiency
It reduces, unit durability shortens.Three, complete machine is completed to can ensure that product quality in factory, avoids site operation to unit bring one
It is a little to influence.
In conventional swimming pool dehumidifier, cold water surface air cooler is mounted on behind reheater condenser.Thus the problem of bringing is: one
As cold water temperature it is identical or slightly higher as refrigeration system evaporating temperature, hot humidity load can not be undertaken again, when reheater condenser work when,
It is reheated after will cause refrigerated dehumidification, the process then to cool down again, energy waste.Or cold water surface air cooler can only compressor not
Start when work, this configuration, refrigeration system is needed by whole configuration of load, and surface air cooler is also required to make by whole configuration of load
It is excessively high at unit initial cost.When needing external heat source auxiliary heating, cold water surface air cooler can not be compatible with other other than hot water
Heat medium.When the winter pond Room needs to dehumidify heating, the Surface cooling coil of postposition can not reach requirement simultaneously.
