Description

Cold air conditioner air source heat pump test device

Technical Field

The utility model belongs to the technical field of heat pump test equipment, concretely relates to cold air conditioner air source heat pump test device.

Background

An air source heat pump is an energy-saving device which utilizes high-level energy to enable heat to flow from low-level heat source air to a high-level heat source. It is a form of heat pump. As the name implies, a heat pump, like a pump, can convert low-level heat energy (such as heat contained in air, soil and water) which cannot be directly utilized into high-level heat energy which can be utilized, thereby achieving the purpose of saving part of high-level energy (such as coal, gas, oil, electric energy and the like).

After the heat pump is produced, whether the cop value (heat generation/energy consumption) of equipment meets the standard or not is detected, so that the product quality is ensured, circulating water is led into a water heat exchanger to be contacted with a heat exchange pipe, high-temperature and high-pressure gas flows in the heat exchange pipe to exchange heat with a water source, so that the circulating water is heated, the water absorption heat value can be known through the rising temperature of water in set time, so that whether the cop value of a product meets the standard or not can be known through detecting whether the rising temperature of the water meets the standard or not, and at present, when the water temperature rises, because the water heating effect of the heat exchange pipe and the water heat exchanger at each position is different, the internal water source cannot rise uniformly, the rising temperature error of general detection is large, the error of a test result is easily caused, and the product quality control does not meet the standard.
