At the same time, due to the poor heat dissipation effect of the cooling tower when the ambient temperature is high in summer, the temperature of the water to be cooled will be high, and the power consumed by the unit will rise linearly. Sometimes the unit will fail and cannot operate normally.
Electric heating or steam is used to heat up the test room, and the operating cost will be relatively high

Abstract
The invention discloses a cold and heat balance device of a heat pump water heater test room. The cold and heat balance device of the heat pump water heater test room comprises a compressor, a three-way adjustment valve A, a heating heat exchanger, a refrigeration heat exchanger, a three-way adjustment valve B, an economizer, a gas-liquid separator, a liquid storage device, a filter, a cold water evaporator, a hot water condenser and a water storage tank. The water storage tank, a water passage of the cold water evaporator and a water passage of the hot water condenser are communicated through one pipe set to form a water circulation system. A refrigerant passage of the cold water evaporator, a refrigerant passage of the hot water condenser, the compressor, the three-way adjustment valve A, the economizer, the gas-liquid separator, the liquid storage device and the filter are communicated through the other pipe set to form a heat pump circulation system. The cold and heat balance device of the heat pump water heater test room has the advantages that the cold and heat balancing, transferring and storage technology is adopted, the temperature requirement of -25-50 DEG C of the test room can be met with a little electric energy serving as driving force, the investment for steam and electric heating equipment is replaced, the investment cost is low, installation and operation are easy, and operation of a system is efficient and saves energy.
Description
technical field [0001] The invention relates to a cold-heat balance device, in particular to a heat-pump hot water machine laboratory cold-heat balance device. Background technique [0002] The air side cooling of the heat pump water heater test room mainly adopts the following methods: when the ambient temperature in the test room is high, a medium-temperature air conditioner is used; when the ambient temperature is low, a low-temperature air conditioner is used. The medium-low temperature air conditioner dissipates heat through a cooling tower. The heating of the air side in the test room mainly adopts electric heating or steam heating. The cooling and unloading mainly adopts multi-head automatic or manual unloading units, so as to achieve the purpose of constant temperature. The initial water temperature of the heat pump water heater relies on the air-cooled hot and cold water machine to raise and lower the temperature. The above-mentioned heating has the following disa...
