Abstract

The utility model discloses an air-conditioning unit for cultivation in a mushroom house, which comprises a direct cooling evaporator. The direct cooling evaporator is arranged on an air treatment pipeline, and the air treatment pipeline is respectively communicated with the inside and outside of the mushroom house through a fresh air adjusting valve and a return air adjusting valve. While the temperature required for growth of mushrooms is maintained, fresh air can be supplied into the mushroom house to provide the atmosphere required for growth of the mushrooms. Moreover, the supplied fresh air can be pre-cooled (or preheated) when the air-conditioning unit is connected with an external heat source (or cold source), the work load of the refrigeration system can be reduced, and the working efficiency of the air-conditioning unit can be increased.

Description

Mushroom house plantation air-conditioning unit

Technical field

The utility model relates to a kind of aircondition that is used to regulate air themperature and freshness, especially is fit to regulate the air-conditioning unit of mushroom planting environment.

Background technology

At present, the plantation of traditional mushroom be adopt plastic tunnel, influenced by seasonal temperature bigger.The mushroom plantation needs suitable temperature on the one hand, and when winter temperature hanged down, mushroom will stop growing; When summer temperature was high, mushroom growth was influenced equally, even dead.The mushroom growth process also needs fresh air on the other hand, absorbs the synthetic nutrient of airborne a large amount of oxygen.Traditional mode adopts to be opened booth and replenishes fresh air, brings the variations in temperature in the canopy like this, and the growth of mushroom is had a negative impact.Though common air-cooled air conditioner unit can provide its needed preference temperature of growing, and can not replenish fresh air, the great amount of carbon dioxide that produces in the process of growth of mushroom can not be got rid of, cause the undergrowth of mushroom.

Summary of the invention

Goal of the invention: in order to overcome the deficiency that existing air-conditioning unit can not replenish fresh air, the utility model provides a kind of air-conditioning unit, and this air-conditioning unit can not only provide mushroom growth needed temperature, can replenish fresh air simultaneously.

In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of air-conditioning unit of mushroom house plantation, comprise direct-cooled evaporator, described direct-cooled evaporator is arranged on the air-treatment pipeline, and described air-treatment pipeline is respectively by new wind control valve, return air control valve and mushroom house inside, mushroom house external communications.

Wherein, be provided with surface cooler in the inlet side of direct-cooled evaporator.

Wherein, described surface cooler comprises precooling zone and preheating section, and described precooling zone, preheating section are communicated with the filling well water below 12 degrees centigrade, 50～60 degrees centigrade boiler water by gate valve respectively.

Mushroom house plantation of the present utility model has the following advantages with the air-conditioning unit: 1) when the required temperature of mushroom growth is provided, can replenish fresh air to mushroom house inside, provide the required a large amount of oxygen of mushroom growth to synthesize nutrient; 2) can regulate, replenish what of amount of fresh air according to actual needs, guarantee the internal circulating load of air-conditioning unit air; 3) by external thermal source (or low-temperature receiver) fresh air that is replenished is carried out precooling (or preheating), reduced the live load of refrigeration system, improved the operating efficiency of air-conditioning unit.

Embodiment:

Below in conjunction with accompanying drawing the utility model is done further explanation.

As shown in Figure 1, mushroom house plantation of the present utility model comprises the refrigerant-cycle systems that many nested structures are identical with the air-conditioning unit, refrigerant-cycle systems comprises compressor 6, the output of compressor 6 is communicated with a port of four-way change-over valve 7, No. two ports of four-way change-over valve 7 by shell and tube exchanger 1 respectively with the input of a check valve 3, the output of refrigerating capillary 4 connects, the output of a check valve 3, the input of refrigerating capillary 4 all is connected with an end of reservoir 2, the other end of reservoir 2 respectively with the output of No. two check valves 16, the input that heats capillary 11 connects, the input of No. two check valves 16, the output that heats capillary 11 all is connected with No. three ports of four-way change-over valve 7 by direct-cooled evaporator 8, and No. four ports of four-way change-over valve 7 are connected with the input of compressor 6 by vapour liquid separator 5.

The inner flow passage connected state of four-way change-over valve 7 is divided into two kinds, and a kind of is that a port is communicated with No. two ports, and No. three port is communicated with No. four ports; Another kind is that a port is communicated with No. three ports, and No. two port is communicated with No. four ports.

Shell and tube exchanger 1 is communicated with the outside well water of irritating by pipeline.

Direct-cooled evaporator 8 is arranged on the air-treatment pipeline of air-conditioning unit, also is provided with surface cooler 9 in the inlet side of direct-cooled evaporator 8, and surface cooler 9 comprises precooling zone and preheating section.Precooling zone is communicated with the outside well water of irritating by gate valve 10; Preheating section is communicated with external boiler water by gate valve 10.

The temperature of irritating well water is below 12 degrees centigrade; The temperature of external boiler water is more than 50 degrees centigrade, below 60 degrees centigrade.

Refrigerating state: the output of the compressed machine 6 of cold-producing medium is discharged, through a port of four-way change-over valve 7, No. two ports of four-way change-over valve 7, shell and tube exchanger 1, check valve 3, fluid reservoir 2, refrigerating capillary 11, direct-cooled evaporator 8, No. three ports of four-way change-over valve 7, No. four ports of four-way change-over valve 7, vapour liquid separator 5, get back to compressor 6, discharge by compressor 6 compression backs, finish cold-producing medium circulation under the cooling condition.

Heat state: the conversion of four-way change-over valve 7 inner flow passage connected states, the output of the compressed machine 6 of cold-producing medium is discharged, through a port of four-way change-over valve 7, No. three ports of four-way change-over valve 7, direct-cooled evaporator 8, No. two check valves 16, fluid reservoirs 2, No. two ports that heat capillary 4, shell and tube exchanger 1, four-way change-over valve 7, No. four ports of four-way change-over valve 7, vapour liquid separator 5, get back to compressor 6, discharge by compressor 6 compression backs, finish cold-producing medium circulation under the heating condition.

As Fig. 2,3, shown in 4 and 5, new wind control valve 12 is installed above the cabinet 16 of air-conditioning unit, return air control valve 13 is installed at cabinet 1 rear at the air-conditioning unit, the air intake of air-treatment pipeline is respectively by new wind control valve 12, return air control valve 13 and mushroom house inside, the mushroom house external communications, the air-conditioning unit adopts new wind control valve 12 to replenish fresh air, can also replenish what of amount of fresh air by regulating, also be respectively equipped with new air-valve regulating handle 14 and the air returning valve regulating handle 15 that is used to regulate air mass flow at new wind control valve 12 and return air control valve 13 with return air control valve 13 combination.Blower fan 17, direct-cooled evaporator 8 and surface cooler 9 are arranged on the inside of unit cabinet, and the outlet air end of air-treatment pipeline is by blower fan 17 and mushroom house internal communication.
