Technical Field
[0001] This utility model relates to the field of constant temperature system technology, and in particular to a constant temperature system for culture chambers. Background Technology
[0002] A plant culture chamber is a specialized laboratory environment used for plant tissue culture and propagation. Temperature is one of the important environmental factors for plant growth and development, and the temperature in a plant tissue culture chamber is generally controlled between 20-25 degrees Celsius. Within this temperature range, the metabolic activity and growth rate of plant cells reach their optimal state, which is conducive to rapid propagation and growth. When controlling the temperature in a plant tissue culture chamber, it is also necessary to pay attention to temperature stability, as fluctuations and instability can adversely affect plant growth and development.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.
[0013] The constant temperature system of the culture room includes a compressor 1. A one-way valve a2 is installed at the rear end of the compressor 1. A three-way valve a15 is installed at the rear end of the one-way valve a2. One end of the three-way valve a15 is connected to an air conditioning four-way valve 3, and the other end is equipped with auxiliary compensation.
[0014] The air conditioning four-way valve 3 has an E outlet, an S outlet, and a C outlet. The E outlet is connected to the indoor unit 4. The S outlet is connected to a regenerative gas distributor 6, which is connected to the compressor 1. The C outlet is connected to the outdoor unit 7. The other end of the outdoor unit 7 is connected to a one-way valve b8. The one-way valve b8 is connected to a liquid receiver 9. The outlet of the liquid receiver 9 is equipped with a normally open valve. The normally open valve is equipped with a filter 10. The filter 10 is connected to a solenoid valve 11. The solenoid valve 11 is connected to a sight glass 19. The sight glass 19 is connected to an electronic expansion valve a12. The electronic expansion valve a12 is equipped with a one-way valve d13, which is connected to the other end of the indoor unit 4.
[0015] A temperature probe 5 is installed on the indoor unit 4. When the temperature probe 5 detects that the indoor temperature is higher than the set temperature, the cooling mode is activated. The heat is absorbed by the liquid receiver 9 through the indoor unit 4 and then enters the regenerating gas separator 6. The compressor 1 discharges the heat at the outdoor unit 7, thereby reducing the indoor temperature.
[0016] The indoor unit 4 is also equipped with a one-way valve C22, which is connected to the liquid receiver 9. An electronic expansion valve B14 is also located at the rear end of the sight glass 19, and is connected to the outdoor unit 7. When the temperature probe 5 on the indoor unit 4 detects that the indoor temperature is lower than the set temperature, the heating mode is activated. Heat is released through the liquid receiver 9, the outdoor unit 7, the regenerative gas separator 6, and the compressor 1, before entering the indoor unit 4 to increase the indoor temperature.
[0017] The constant temperature system of the incubation room also includes auxiliary compensation, which includes a three-way valve a15 located between the one-way valve a2 and the four-way air conditioning valve 3. The other end of the three-way valve a15 is equipped with a three-way valve b16. One end of the three-way valve b16 is connected to a constant pressure valve a17, which is connected to the rear end of the one-way valve. The other end of the three-way valve b16 is equipped with a constant pressure valve b18, which is connected to the rear end of the outdoor unit 7.
[0018] An electronic expansion valve c20 is connected between the solenoid valve 11 and the sight glass 19, and the electronic expansion valve c20 is connected to the compressor 1.
[0019] A safety valve 21 is installed above the liquid reservoir 9 to increase the safety of the liquid reservoir 9.
