Description

Desiccant adsorption heat precooling and desiccant regenerative heat supply type water source heat pump system

The present invention relates to a water source heat pump system for precooling desiccant adsorption heat and supplying desiccant regenerative heat, and more particularly, to a desiccant capable of preheating and precooling air passing through a desiccant air conditioner using an underground heat source. It relates to a water source heat pump system of adsorption heat precooling and desiccant regenerative heat supply type.

Conventional air conditioning (cooling and dehumidification) was generally performed by an air conditioner. The air conditioning method using the air conditioner is a system in which a refrigerant is circulated between an indoor unit and an outdoor unit to release heat from an indoor side having a low temperature to an outdoor air side having a high temperature.

In the cooling operation of the conventional air conditioner, the refrigerant takes heat from the indoor air in the indoor unit, evaporates, moves to the outdoor unit, compresses the refrigerant by the compressor in the outdoor unit, cools and condenses into the outdoor unit, and releases the heat to the outdoor unit. By taking away the heat of evaporation, the indoor air is cooled and cooling is possible.

In the dehumidifying operation of the conventional air conditioner method, the water vapor contained in the indoor air is cooled to a condensing temperature and the air and moisture are separated.

In general, since the condensation temperature is lower than the temperature suitable for air conditioning, it is not appropriate to supply excessively cooled air to the room as it is because it may impair comfort. Therefore, it is preferable to reheat the cooled air and adjust it to an appropriate temperature before supplying it to the room. Therefore, the operation of cooling and reheating has become necessary.

Accordingly, recently, a desiccant air conditioning system is mainly used. Desiccant refers to a moisture absorbent that absorbs moisture, and the desiccant dehumidification method is a direct air conditioning method in which moisture is removed and separated by a moisture absorbent. This desiccant air conditioning method can supply air of an appropriate temperature and humidity to a room by cooling the dehumidified air.

The desiccant air conditioner has a sensible heat exchanger that exchanges heat with air, a regeneration heater that heats the air that has passed through the sensible heat exchanger, a dehumidifier that removes moisture through the air heated by the regeneration heater and dehumidifies the outside air, and a sensible heat supply after dehumidification. It includes an air conditioner that finally cools the air cooled through the exchanger.

However, these desiccant air conditioners consume electricity to heat the regenerative heater, and the cooling efficiency of the hot air supplied after dehumidification is not high through heat exchange in the sensible heat exchanger. Since it is cooled at the temperature, electrical consumption for driving the regenerative heater and the air conditioner is severe, which increases energy consumption of the desiccant air conditioner, and increases the cooling efficiency and energy consumption for cooling due to the high load of the air conditioner.

In the water source heat pump system of the desiccant adsorption heat precooling and desiccant regenerative heat supply type according to an embodiment of the present invention, the exhaust air passing through the exhaust duct 101 of the desiccant air conditioner 100 is transferred to the refrigerant high-temperature condenser ( 104) preheats the exhaust air before being heated by heat exchange, and precools the supply air before the supply air passing through the supply air duct 102 of the desiccant air conditioner 100 is cooled by heat exchange in the refrigerant evaporator 105. The refrigerant high-temperature condenser 104 heats the exhaust air and the refrigerant evaporator 105 can save energy required to cool the supply air, and it is possible to reduce the energy required for preheating the exhaust air and pre-cooling the supply air. Since the heat source 610 is used, power consumption for cooling can be reduced, and thus energy consumption efficiency of the desiccant air conditioner 100 can be improved.

On the other hand, the inner surfaces of the exhaust duct 101 and the air supply duct 102 of the desiccant air conditioner 100 of the water heat source heat pump system of the desiccant adsorption heat precooling and desiccant regenerative heat supply type according to an embodiment of the present invention An antifouling coating layer made of an antifouling coating composition may be applied to effectively prevent adhesion and removal of contaminants.

The antifouling coating composition contains tetraethyl ammonium hydroxide and methyl ethyl ketone (MEK) in a molar ratio of 1:0.01 to 1:2, and the total content of tetraethyl ammonium hydroxide and methyl ethyl ketone is the total aqueous solution It is 1 to 10% by weight relative to.

The molar ratio of the tetraethyl ammonium hydroxide and methyl ethyl ketone is preferably 1:0.01 to 1:2, and when the molar ratio is out of the above range, the coating properties on the exhaust duct 101 and the air supply duct 102 are reduced or There is a problem in that the coating film is removed due to increased water adsorption on the surface after application.

The tetraethyl ammonium hydroxide and methyl ethyl ketone are preferably 1 to 10% by weight of the total aqueous solution of the composition. If the content is less than 1% by weight, there is a problem in that the coating properties on the exhaust duct 101 and the air supply duct 102 are lowered. , when it exceeds 10% by weight, crystallization is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the composition for antifouling coating on the exhaust duct 101 and the air supply duct 102, it is preferable to apply the composition by a spray method. In addition, the final coating film thickness on the exhaust duct 101 and the air supply duct 102 is preferably 700 to 2500 Å, more preferably 900 to 2000 Å. If the thickness of the coating film is less than 700 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2500 Å, there is a disadvantage in that crystallization of the coated surface is easy to occur.

In addition, this antifouling coating composition can be prepared by adding 0.1 mol of tetraethyl ammonium hydroxide and 0.05 mol of methyl ethyl ketone to 1000 ml of distilled water, followed by stirring.

The reason why the ratio of the constituent components and the thickness of the coating film were numerically limited as described above was that the present inventors showed the optimal antifouling coating effect at the ratio as a result of analyzing the test results while repeating several failures.

A fragrance material for the environment mixed with functional oil may be coated.

The mixing ratio of the fragrance material and the functional oil is 95 to 97% by weight of the fragrance material and 3 to 5% by weight of the functional oil, and the functional oil is 50% by weight of Patchouli oil and tansy oil. It consists of 50% by weight.

Here, the functional oil is preferably mixed in an amount of 3 to 5% by weight based on the fragrance material. If the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant, and if the mixing ratio of the functional oil exceeds 3 to 5% by weight, the effect is not greatly improved, but economical efficiency is poor.

Patchouli oil has good effects on stress relief, tension relief, and sterilization, and Tansy oil has excellent effects on sterilization, bacteriostatic action, and treatment of infections.

Therefore, as the fragrance material mixed with these functional oils is coated on the surface of the refrigerant evaporator 105, the surface of the refrigerant evaporator 105 is sterilized and the stress of the user in the room where cooling is supplied is reduced. can be obtained.

The reason for limiting the components and limiting the numerical value of the mixing ratio for the environmental fragrance material and functional oil is that the present inventors have repeatedly failed several times and analyzed the test results to find that the above components and numerically limited ratio are optimal showed the effect of

The adhesion enhancer may include 60 parts by weight of water, 17 parts by weight of 2-heptadecylimidizol, 15 parts by weight of N-acyl taurate, 7 parts by weight of ammonium persulfate, and 1 part by weight of sodium acetate.

2-Heptadecylimidizol is added to improve adhesion and hardening acceleration, N-acyltaurinate acts as a surfactant, ammonium persulfate acts as a catalyst, and sodium acetate acts as a buffer. .

The reason for limiting the constituent materials and components and limiting the numerical values of the mixing ratios as described above is that, as a result of the present inventors' analysis through test results while repeating several failures, the optimal effect in the constituent components and numerically limited ratios was obtained. showed up

In addition, a vibration absorption unit may be further installed at the lower end of the compressor 200 .
