For humidity control system of the invention, using integrated heat exchanger replacement pair in traditional hot and cold water regulating system
The plate heat exchanger and water side electric heater answered, water route project installation part increase water route water mixing valve regulating system.
Indoor pusher side, refrigerant are recycled by the closing water in refrigerant coil pipe and integrated heat exchanger and are carried out in system operation
Heat exchange, while the reliabilities component such as the electric heating of water side, expansion drum, automatic exhaust steam valve is directly integrated in heat exchanger, is led to
The leaving water temperature for crossing integrated heat exchanger controls the opening and closing of the electric heater in low temperature environment, passes through expansion drum stability contorting
Water route side pressure fluctuation, automatic exhaust steam valve guarantee the air emptying function of the water system of water side.
In the project installation part of complete machine, closed waterway water realizes unit by the opening and closing of triple valve, water mixing valve
Floor 90, air-conditioning (wind disk 80), the functions such as water tank 70.When user needs to realize different function output simultaneously, such as winter
During heating, floor heating and air-conditioning heating carry out simultaneously, therefore closed waterway circulation should run high water temperature circulation and meet sky
Modulate the efficient quick requirement of heat, but floor using but cannot high water temperature circulation in order to avoid cause floor overheating deforming, therefore need
Different heating capacity requirements is exported simultaneously.By increasing water mixing valve in floor side, pass through the aperture control of logic control water mixing valve
Floor water return amount processed reduces floor inflow temperature in high water temperature round-robin basis, realizes that the different heating capacities of different function demand are defeated
Out.
Integrated heat exchanger is by components collection such as plate heat exchanger, electric heater, expansion drum, the safety valves of traditional water route part
At optimization, interior machine mounting area is reduced, using coil heat exchange, the water of the internal flow of refrigerant coil pipe and tank interior exchanges heat, completely
The water route obstructing problem for avoiding plate heat exchanger plate spacing smaller strip from.Meanwhile for water mixing valve adjusted design, in floor return water
It measures in biggish situation, tank interior water temperature reduces temperature fall off rate due to water is sufficient, to realize complete machine frequency
Numerous number of starts is few, and power consumption is small, and energy saving is high.
Pumps design is taken to be installed as water mixing valve back segment, such design avoids causing in traditional design by water pump is preposition completely
Return water be short of power, water route water under high-head along water return pipeline reverse flow return to heat exchanger cause water route adjust it is disorderly
Disorderly, such water mixing valve regulating system optimization, avoids return water insufficient, and mixed water adjusting is unstable, adjusts the problems such as water temperature fluctuation is big.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Heat exchanger of the invention on body part 10 by being provided with buffer tank 30, so as to realize to accommodating chamber 11
It is automatically replenished the function of first medium.Wherein, body part 10 has the accommodating chamber 11 for accommodating first medium, and heat exchanger tube 20 is set
It sets in accommodating chamber 11, for storing first medium, buffer tank 30 is connected buffer tank 30 with accommodating chamber 11.In specifically used mistake
Cheng Zhong, when the first medium in accommodating chamber 11, which is unable to satisfy heat exchanger tube 20, normally to exchange heat, the first medium in buffer tank 30 is certainly
It is dynamic to add in accommodating chamber 11, guarantee that heat exchanger tube 20 normally exchanges heat with this.Heat exchanger of the invention on body part 10 by setting
It is equipped with buffer tank 30, so as to realize to the function of being automatically replenished first medium of accommodating chamber 11, is solved in the prior art
Heat exchanger the problem of cannot being automatically replenished.
Heat exchanger of the invention, which solves interior machine heat exchanger and electric heater independent design, leads to interior machine structure size mistake
The big and frequent start-stop of unit or long-term low-frequency operation problem, using heat exchanger and electric heating Integrated design technology, exchange heat pipe dish
Serpentine design, and be immersed in interior machine vessel water, electric heating heating element is then placed in heat exchange coil central part while being inverted peace
Dress, the interior machine structure size of this design optimization avoid electric heater from bottom and install fixed leakage hidden trouble, while interior equipment is standby
One constant volume water volume, complete machine are controlled according to the temperature sensing package detection temperature being distributed in container internal water, reach set temperature i.e.
End target water temperature water requirements are really realized in shutdown, avoid asking using the frequent startup-shutdown of water management or long-term low-frequency operation out
Topic.
Humidity control system of the invention solves traditional air-to-water heat pump can not warm up blower with using simultaneously
Coil pipe problem, due to air-to-water heat pump specific time can only provide particular water temperature give end use, when user simultaneously
Warm up with needing to open wind disk when, both cannot be considered in terms of water temperature requirement, refrigeration supply water temperature is too low, will appear grounding heat coil tube table
Face condensation, the water supply water temperature over-high then unobvious problem of fan coil refrigeration effect, heating supply water temperature is too low, and fan coil goes out
It now blows a cold wind over problem, the excessively high then easy floor deformation of supply water temperature.In order to solve the above problem, floor heating circuit and fan coil circuit
(or tank hot water circuit) is supplied water using different water pumps, and water mixing valve is arranged on floor heating circuit, and air-cooled cold (heat) water dispenser group presses blower
The operation of water temperature needed for coil pipe (or water tank water heating), grounding heat coil tube aspect use water mixing valve bypass to adjust from the unit booting moment
Section, bypass return water are mixed with water inlet, and refrigeration then improves grounding heat coil tube water supply, and heating then reduces grounding heat coil tube water supply, thus
Above-mentioned floor heating condensation or problem on deformation are avoided, single pumps design waterpower imbalance and ground warming plate can then be solved using double water pump design
Dynamical problem needed for managing mixed water.
