Problems solved by technology

However, ordinary ice-storage air conditioners flow low-temperature refrigerants such as brine or ethylene glycol solution in the cold storage coils, which need to be circulated by pumps, and there is a decrease in refrigerant pressure caused by the long pipeline of the direct refrigerant evaporation system. And the disadvantages of difficult oil return; in addition, the liquid low-temperature secondary refrigerant (such as brine or ethylene glycol solution, etc.) is also corrosive to the pipeline of the system

Embodiment Construction

[0024] A heat pipe cold storage air conditioner according to the present invention, comprising an indoor unit 1, an outdoor unit 2, a compressor 21, a condenser 22, a throttle valve 231 for air conditioning, a throttle valve 232 for cold storage, and solenoid valves 241, 242, 243 , 244, 245, 246, evaporator 25 for air conditioning, evaporator 26 for cold storage, heat pipe 27, cold storage tank 28, circulation pump 29. The dry filter, gas-liquid separator and electronic control part are omitted in the accompanying drawings. The indoor units 1 can be connected in parallel in multiple groups as required, and only one group of indoor units 1 is shown in the figure for illustration.

[0025] When performing a conventional air-conditioning refrigeration cycle, the solenoid valves 242, 244, 246 are closed, and the solenoid valves 241, 243, 245 are opened. The refrigerant is compressed by the compressor 21 and discharged, flows to the condenser 22 to release heat, and the condensed ...

Abstract

This invention discloses a kind of heat pipe cooling accumulator air conditioner device. Indoor machine set is composed of fan and heat exchanging coil pipe; for outdoor machine set, upside condensation segment of heat pipe is positioned in evaporator, while the underside evaporation segment in the cooling accumulating tank which is filled with cooling medium; the inlet of compressor respectively connects to the outlets of evaporator using for air conditioner and cooling accumulation, while the outlet to the inlet of condenser; the outlet of condenser respectively connects to the inlets of evaporator using for air conditioner and cooling accumulation through magnetic valve and stop valve; indoor machine set respectively connects to the inlets of evaporator using for air conditioner and cooling accumulating tank through magnetic valve; the evaporator using for air conditioner and cooling accumulating tank all connect to the inlet of circulating pump through magnetic valve; the outlet of circulating pump connects to indoor machine set. This invention has short pipeline. It avoids decreasing of refrigerants pressure.

Description

technical field [0001] The invention relates to a refrigeration air conditioner, in particular to a heat pipe cold storage air conditioner. Background technique [0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. As one of the basic industries of the national economy, the energy industry has achieved considerable development. However, the development of the energy industry still cannot meet the needs of the rapid development of the national economy and the rapid growth of people's daily energy consumption, and the national energy shortage situation still exists. [0003] To solve the current energy shortage problem, we can start from two aspects: one is to develop renewable energy (such as solar energy, biomass energy, wind energy, ocean energy, etc.), and the other is to save the energy currently used. my country's energy utilization efficiency is 10 percentage points lower than t...
