Heat pump type incubator temperature control device

Abstract

The invention discloses a heat pump type incubator temperature control device. The device mainly comprises a magnetic starter, a double-point temperature control instrument, a low-temperature sensor and a high-temperature sensor, wherein the low-temperature sensor and the high-temperature sensor are arranged in an incubating box and respectively connected with the double-point temperature control instrument; and one end of the magnetic starter is connected with a heat pump host machine compressor, and the other end is connected with the double-point temperature control instrument. The invention favorably solves the problem of frequent starting of the heat pump host machine compressor in a double-point temperature control incubating way; meanwhile, the heat pump type incubator temperature control device is beneficial to the reduction of the starting load of the compressor. In addition, the invention can realize bionic incubation and improve environmental adaptability and survival rate of a hatched young bird.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a temperature control device for a heat pump incubator. Background technique [0002] Traditional electric heating incubators generally use single-point temperature control for incubation, that is, single-point constant temperature incubation is used within a certain incubation period to keep the incubation temperature at a certain set temperature for a certain period of time. The heat pump incubator extracts the heat in the soil of the incubator or the outside air through the thermal cycle of evaporation and condensation as a heat source to maintain a constant temperature for incubation. The power of the thermal cycle comes from the compressor in the heat pump unit. When the heat pump incubator adopts the above control method, as long as the actual temperature in the incubator is lower than the preset temperature, the compressor will start, and frequent starts will shorten the lif...

AI Technical Summary

Problems solved by technology

When the heat pump incubator adopts the above control method, as long as the actual temperature in the incubator is lower than the preset temperature, the compressor will start, and frequent starts will shorten the life of the equipment or even burn out the compressor, because the motor of the compressor The starting current is about 7 times of the rated current, which is often easy to burn the motor insulation paint
