Abstract

The utility model relates to a domestic fresh air dehumidifier, which belongs to central air-conditioning air treatment equipment, can be used for cooling and dehumidifying air, and can be used for heating fresh air in winter. The fresh air dehumidifier is formed by a chassis, a total heat recovery device, an evaporator, a compressor, an expansion valve, a condenser, a heating coil, an air valve, a filter, a fresh air fan, an exhaust fan and other main equipment. The domestic fresh air dehumidifier has two modes of fresh air and total return air; after being cooled and dehumidified through the total heat recovery device, the fresh air is dehumidified again through the evaporator of a Freon compression-type refrigerating system; the evaporation temperature is lower than conventional water temperature; the dehumidification capacity is strong; and the dehumidification effect is good. The dehumidified fresh air is heated through the heating coil, so that the temperature and the humidity of air supply are controlled. Hot water of the heating coil comes from the condenser of the compression-type refrigerating system, so that a heat source has no need to be provided independently. A total return air work condition can be started through controlling the on and the off of the air valve, so that rapid cooling and dehumidifying are realized.

Description

Family formula fresh air dehumidification machine

Technical field

The utility model belongs to the residential central air-airhandling equipment, can be used for the fast-refrigerating dehumidifying to air.

Background technology

Building energy consumption is the principal mode of energy resource consumption, and building energy conservation has formed global megatrend, also is a basic trend of modern technologies development.Simultaneously, improve Indoor Environmental Quality, improve comfort level, reduce environmental pollution and also become more and more important and urgent.

Generally believe that at present the humiture autonomous control system is a valid approach that solves traditional air-conditioning drawback, has very big development prospect in future.

The humiture autonomous control system, adopt two systems independently of overlapping control respectively with conditioning chamber in temperature and humidity, thereby avoided the reduction of the energy waste that the humiture Combined Treatment is brought in the conventional system and air quality; Regulate humidity by wind system, the terminal temperature of regulating of sensible heat can satisfy the requirement that the room heat moisture ratio constantly changes.

Radiation air-conditioner can well be combined with the low energy consumption green building as a kind of energy-saving air conditioning system, and good prospects for application is arranged, and has also obtained development fast in recent years.Its principle is that cold and hot matchmaker transfers energy to radiating surface by radiant coil, radiating surface again by convection current and radiation and based on the mode of radiation directly and indoor environment carry out heat exchange.

In order to guarantee the operational effect of radiation air-conditioner, generally to be equipped with VMC, and at southern area, especially in summer, if in the direct inlet chamber of the new wind of outdoor high temperature high humidity, the one, increased indoor air humidity, with the risk of dewfall, the 2nd, increased the load of indoor radiating system, so must dehumidification treatments to new wind.

The fresh air dehumidification machine is with after the outdoor air dehumidifying, by the fresh wind tube road with relatively dry and reach target relative humidity air deliver to indoor, to reach comfortableness or manufacturability indoor environment humidity demand.

Adopt maximum still freeze drying in the market, in dehumidifying, temperature is also along with decline.This mode of independent humidity control is called constant temperature dehumidification by the insider, and its basic principle is to be heated to certain temperature again by the chilled air of dehumidifying, and then sends into indoorly, and indoor environment has kept constant relatively under the situation of humidity decline like this.Mainly contain two kinds of technology at present, the one, adopt the chilled water coil cool-down dehumidification, and then utilize hot-water coil pipe or electrical heating to heat up, this just need have extra hot water source, and that electrical heating can consume a large amount of electric energy is uneconomical.Also having a kind of is directly to utilize compression refrigeration equipment to dehumidify, heat up with the condenser heat extraction, if but the dehumidifying duty ratio is bigger, and compressor relatively takes electricity, and condenser heat also can't pass through the new wind of heat separately again and get rid of.

Summary of the invention

The utility model proposes a kind of efficient, energy-conservation fresh air dehumidification machine at above problem, by rational design, solved the problem of present existence, and can follow the ingenious combination of radiation water system.

The utility model relates to a fresh air dehumidification machine, and described family formula fresh air dehumidification machine comprises a casing, has been divided into two zones by baffle plate and full heat recovery device in the casing, and one is the air draft zone, and one is the air-supply zone.Described air draft zone comprises the air draft blower fan at exhaust outlet and exhaust outlet place, full heat recovery device, and be arranged on the return air inlet of return air filter import department.Described air-supply zone comprises the new wind air inlet that is arranged on new wind filter import department, full heat recovery device, the sweat cooling closed circuit that is made of compressor, condenser, evaporimeter, expansion valve, and the new wind blower fan at new wind air outlet and new wind air outlet place.

Compare with existing refrigerated dehumidification equipment, characteristics of the present utility model are:

New wind and air draft are carried out the energy recovery by full heat recovery device, and wetting by heat exchanges, and utilize air draft can realize can reducing place capacity and the power consumption that dehumidifies to the effect of the pre-dehumidifying of pre-cold-peace of new wind.

Thereby refrigeration working medium directly evaporates heat absorption in evaporimeter carries out cool-down dehumidification to new wind, has lower temperature than common water coil, and effect on moisture extraction is better.

Summer air-conditioning water preferentially enters condenser, reclaims the condensation heat extraction of compressor, and water temperature enters heat(ing) coil after raising again, and new wind is carried out heat again.

The baffle plate place in return air inlet and new wind zone is equipped with return air bypass air-valve, and during new wind operating mode, bypath valve is closed, and return air drains into outdoor by the air draft blower fan and carries out energy exchange with new wind.New wind passes through heat reclamation device successively, evaporimeter, and heat(ing) coil is delivered to indoor by new wind blower fan.During the return air operating mode, the return air by-passing valve is opened, and new air-valve and exhaust valve are closed, and return air passes through the return air by-passing valve successively, evaporimeter, and heat(ing) coil, the back of being dehumidified is sent into indoor by new wind blower fan.

Advantage of the present utility model is:

(1) simple in structure, be applicable to family formula installation.

(2) have special full heat recovery device, energy recovery efficiency height, winter operation do not freeze.

(3) adopt the compression refrigeration dehumidifying, effect on moisture extraction is better than water-cooled.

(4) special pipeline connects, and can directly utilize air conditioner water summer, reclaims the condenser heat extraction the new wind after dehumidifying is carried out heat again.

(5) be provided with the return air by-passing valve, have new wind and complete two kinds of operating modes of return air, can realize quick dehumidifying.

(6) dual-use, can heat new wind winter dehumidifier as new blower fan group.

(7) can realize winter aestival aspect supply and return water temperature together with the water system perfect adaptation of radiation air-conditioner.
