Device for testing energy-saving water source heat pump performance coefficients

Abstract

The invention discloses a device for testing energy-saving water source heat pump performance coefficients. The device comprised a tested unit, a cold water circulation loop, a hot water circulation loop, a mixed water circulation loop and a compensation loop, an evaporator of the tested unit is connected with the cold water circulation loop through a soft connector, a condenser of the tested unit is connected with the hot water circulation loop through a soft connector, and the mixed water circulation loop exchanges heat with the cold water circulation loop and the hot water circulation loop respectively. The device adopts plate-type heat exchangers to respectively replace a hot water tank and a cold water tank, size of a test board is reduced, and the test board is simple and compact in structure. Circulation water quantity is substantially reduced, the temperature of water in cold (hot) plate exchange loops is rapidly achieve needed temperature, time for pre-heating or pre-cooling circulating water is reduced, and accordingly consumption of electrical energy is greatly reduced, and a purpose of saving energy is achieved.

Description

[0001] technical field [0002] The invention relates to an energy-saving water source heat pump performance coefficient testing device. Background technique [0003] In the production process of water source heat pump manufacturers, how to optimize the unit system and how to improve the energy efficiency and reliability of the system is the key technology of the manufacturer. Therefore, it is necessary to carry out operation and debugging for each product to check whether the operation performance of the product meets the relevant national standards; the relevant functional departments of the state also conduct random inspections or other inspections on the products of each manufacturer to ensure that the products of each manufacturer are Pass rate. [0004] Most of the traditional water source heat pump performance testing devices adopt the water tank type, that is, the test bench contains three water tanks, namely the hot water tank, the cold water tank and the mixed (me...

Problems solved by technology

[0007] This kind of conventional performance test bench not only needs a long warm-up (cold) time (for example, it takes a long time to warm up the water in the hot water tank to 30°C before the test in winter), but , The hot water temperature fluctuates greatly (during the actual test, the temperature deviation between the inlet and outlet water will exceed ±1°C), which is difficult to control

This not only wastes power, but also affects test efficiency
