Energy-saving temperature adjusting device and control method thereof

Abstract

The invention provides an energy-saving temperature adjusting device and a control method thereof. The technical problem that an existing temperature adjusting device cannot meet the cooling requirement, the installation space and the cost at the same time can be solved. The energy-saving temperature adjusting device comprises liquid cooling systems and is characterized in that the number of the liquid cooling systems is two; the two liquid cooling systems share a PTC liquid heater and an expansion kettle, and a compressor, a condenser, an expansion valve and a refrigerant circulation pipeline of a heat exchanger are sequentially connected to form a refrigerant circulation loop; the expansion kettle, the water pump, the first electromagnetic valve, a cooling liquid circulation pipeline of the heat exchanger, the second electromagnetic valve and a cooling liquid circulation pipeline of temperature adjusting target equipment are sequentially connected to form a cooling liquid circulation loop, and the first electromagnetic valve, the PTC liquid heater and the second electromagnetic valve are connected to form a heating branch; the compressor, the condenser, the expansion valve, the heat exchanger, the water pump, the first electromagnetic valve, the second electromagnetic valve and the PTC liquid heater are all in electric control connection with the controller.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to an energy-saving temperature adjustment device and a control method thereof. Background technique [0002] Existing temperature adjustment devices are generally equipped with a liquid cooling system. When the working environment of the target equipment is harsh, its temperature generally exceeds the preset upper limit, and a liquid cooling system cannot meet the cooling requirements of the target equipment. If a liquid cooling system is directly added to the temperature adjustment device, not only the installation space requirement is larger, but also the cost is higher. In addition, the existing control method of the temperature regulating device generally directly heats / cools the circulating cooling medium (such as cooling water) at full load, which not only consumes a lot of energy, but also consumes parts quickly.
