Description

Direct-burning type single heat split air conditioner

The utility model relates to a kind of direct-burning type single heat split air conditioner, belongs to fuel oil (gas) conditioner technical field.

Existing heat pump detachable air conditioner is applicable to-5 ℃ to 43 ℃ environment temperature, is being lower than under-5 ℃ the cold environment to move.The electroheating type air-conditioner can move under cold environment, but power consumption is big, and the occasion that is not suitable for being restricted at delivery is used.And common heating boiler is formed big-and-middle-sized heating system mostly, and the villa that disperses for small size, yurt, sentry post, vehicle etc. can't adopt.

The purpose of this utility model overcomes the deficiencies in the prior art exactly, provides that a kind of power consumption is little, efficient is high, heating capacity is at 10000-90000W, air-conditioner that can heat supply under 0 ℃ to-25 ℃ cold environment.

In order to achieve the above object, the utility model is a thermal source with fuel oil (gas), is heat transfer medium with the atmospheric steam.Adopt the structural shape of direct-burning type single heat split air conditioner.The utility model only needs small-power power to drive auxiliary equipment and control circuit, and every generation 10000W heat required electric power is about 100W.Open-air available solar energy cell panel-battery system power supply in the unregulated power supply.The technical solution of the utility model is: convert the chemical energy of fuel oil (gas) to heat energy based on the outdoor unit of direct combustion type atmospheric pressure kiln, the single flow atmospheric pressure kiln produces atmospheric steam after absorbing heat energy; Provide atmospheric steam by steam pipe to indoor units; Indoor units adds hot-air by heat exchanger with the heat of steam, and by cross flow fan to the indoor hot blast that send, by humidifier valve air is carried out humidification, regulate the humiture of room air, reach the purpose of winter air-conditioning; Steam after the heat release becomes water with fixed attention, and unit outside water pipe return chamber enters next circulation again.Only need arrangements of operations at indoor wire remote control devices during operation, just can finish whole programs of sending vapour from lighting a fire to automatically, safely, and control the start and stop of burner according to indoor temperature automatically.In order to ensure starting successfully at the low temperature environment below 0 ℃, outdoor unit of the present utility model adopts heating tape and electric heater for heating light diesel fuel and combustion air, and employing flue gas-air preheater and flue gas-light diesel fuel heater, the completing combustion of diesel oil when moving with the assurance system.

The utility model is made of split type chamber, inside and outside unit, adopt detachable fitting to be connected with pipe fitting, and on-the-spot mounting or dismounting are convenient, can make portablely, is applicable to the application of field work place.The utility model adopts the direct current atmospheric pressure kiln, produces atmospheric steam, security of operation, and quick heating, weight and size are little; Indoor units adopts phase-change heat-exchanger and forces flowing heat transfer, and efficient height, heating load are big.

This device is the energy with diesel oil or combustion gas, and operating cost is low; Systematic working medium is a water, and it is convenient to replenish, environmentally safe.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model direct-burning type single heat split air conditioner.

Fig. 2 is steam-water circulation system figure of the present utility model.

Fig. 3 is a control flow chart of the present utility model.

As shown in Figure 1, the utility model is by outdoor unit 3 with pass inside and outside body of wall 12 junction chambers water pipe 9, steam pipe 10 and the cable 11 etc. of unit and form.Outdoor unit 3 can be placed in away from indoor units 1 about 5-20m place, and noise that produces when making the work of outdoor unit and used heat is away from the room, with peace and quiet in the holding chamber and humiture adapt circumstance.Outdoor unit 3 is made up of fuel oil (gas) burner 4, fuel tank (air receiver) 5, direct current heat exchange coil 7, water circulating pump 8, flue gas-air and light oil preheater 6 etc., its major function is that fuel oil (gas) chemical energy is converted to heat energy, and the water in the heating direct current heat exchange coil 7, carry to indoor units 1 as catalyst carrier behind the generation atmospheric steam.Indoor units 1 is made up of control panel 13, steam inlet pipe 14, steam-air heat exchanger 15, airstrainer 16, shell 17, air door 18, cross flow fan 19, expansion tank 20, humidifier valve 21 and wire remote control devices 22 etc., its major function is that room air is heated and adds wet process, and to indoor air-supply, the comfortable humiture of routine indoor maintenance.The pipe of the inside and outside unit of junction chamber and the effect of bunch of cables 2 are to indoor delivering vapor, return and coagulate water and transmitting electric power and control signal.

Operation principle of the present utility model is as shown in Figure 2: after direct-burning type single heat split air conditioner started, the fuel oil of outdoor unit 3 (gas) burner 4 was lighted, and wind and oil are delivered to combustion chambers burn, produced high-temperature fuel gas; Become atmospheric steam after in direct current heat exchange coil 7, forcing mobile water to absorb heat, deliver to indoor units 1 through stop valve 23 and steam pipe 10; Steam is the condensation heat release in steam-air heat exchanger 15, and heat is forced flow air to absorb by blower fan 19, and hot-air is to indoor conveying; Condensed water is sent direct current heat exchange coil 7 back to through expansion tank 20, water pipe 9 and stop valve 23, water circulating pump 8, finishes a circulation.In order to improve the humidity of room air, by magnetic valve 26, steam jet 25 to the air wetting of handling through air-conditioner.

The hot detachable air conditioner of the utility model list is in order to be applicable to 0--25 ℃ low temperature environment, when starting, adopted heating tape and pre-heating oil of electric heater and combustion air, when normal operation, adopted flue gas-air and light oil preheater 6 to guarantee the completing combustion of light diesel fuel.

Fig. 3 is a control flow chart of the present utility model.After pressing remote controller startup button, power connection, water circulating pump 8 starts running, and the water in the expansion tank 20 is pumped into DC tube, whether adopt the microwave transmitting and receiving transistor to monitor has water to flow in the DC tube, flow if any water, then water shutoff switch is in path, the master controller energising, enter the combustion ignition program, scavenging promptly-ignitor energising produces electric spark-fuel valve energising and opens, and oil gun oil atomizing-fuel oil is lighted, and equipment enters normal operation.If want burn-out or room temperature to reach setting value, the temperature relay closure, its signal input main controller, main controller sends instruction and cuts off fuel valve, burn-out, and burner carries out the back scavenging, be reduced to differential values when following until room temperature, temperature relay is opened a way again, again signal is imported main controller, enters the automatic combustion ignition procedure.In control procedure, burner ON/OFF bang-bang action.

The utility model control system adopts four kinds of protections: (1) water cut-off protection, if water shutoff switch monitors and anhydrously in the DC tube flows the main controller no power when starting; When normal operation, monitor anhydrous flowing in the DC tube, sound and light alarm then, and send instruction by main controller and cut off fuel valve, burner carries out the back scavenging.(2) unsuccessful as lighting a fire, signal input main controller is reported to the police and is carried out scavenging.(3) the undesired or disconnected wind of indoor units cross flow fan can be reported to the police.(4) burner extinguishes in the running, can report to the police and the back scavenging.

The utility model control system comprises combustion ignition, and normal operation and three links of automatic protection are simple to operation, guarantee system safety operation.

The form of its indoor units 1 of the utility model direct-burning type single heat split air conditioner can be wall-hanging, cabinet-type or ceiling-type.
