Energy-saving refrigeration transport cart

Abstract

The invention relates to an energy-saving refrigeration transport cart. The transport cart comprises a fuel gas system, a refrigerating system, a control system and an air feeding and returning system, wherein the fuel gas system is composed of a natural gas storage tank, a pressure reducer, an air mixer and an engine, the refrigerating system is composed of a plate-type heat exchanger, a condenser, a liquid pump, a drying filter, a throttling valve, an air cooler, an air conditioner, an electromagnetic valve and an electric valve in a connected mode, the control system is composed of a controller and a temperature sensor, the air feeding and returning system is composed of an uneven hole plate, an air feeding duct, an air returning baffle and an air returning duct, and a solar storage cell panel is connected with the controller through a control switch. Economical and safe natural gas low in pollution is adopted for the transport cart to be used as fuel, waste heat of exhaust gas is utilized to heat refrigerant when power is provided for the cart, and cooling capacity is provided for a refrigerating compartment and a cab; the solar storage cell panel is utilized to supply power to heat an electric heating wire to defrost the air cooler; airflow organization and a temperature field in the compartment can be controlled evenly, and the purposes of saving energy and protecting the environment are achieved.

Description

technical field [0001] The invention relates to a natural gas refrigerated transport vehicle installed with solar battery panels. Background technique [0002] Refrigerated transportation is a very important and indispensable link in the food cold chain. The main purpose is to transport all kinds of meat, fish, dairy products, bean products, quick-frozen food, fruits and vegetables and frozen, refrigerated and fresh-keeping transportation of cold drinks in supermarkets in the food cold chain. As well as specific industrial demand temperature transportation, transportation of medical vaccines. [0003] The main difference between refrigerated trucks and general vans is that refrigerated trucks are equipped with independent or non-independent refrigerated units. The non-independent refrigerated units work with the power of the car engine, which can make the lowest temperature in the matching cargo compartment reach minus 18 degrees. . An independent refrigeration unit must ...

AI Technical Summary

Problems solved by technology

However, there are some shortcomings. The waste heat after oil combustion cannot be utilized, and the exhaust gas pollutes the atmospheric environment; mechanical refrigerated vehicles need to defrost, which increases fuel consumption; the wind speed and air volume near the air outlet of the evaporator are relatively Large, but the wind speed and air volume far away from the air outlet are relatively small, so the use of uniform perforated plates cannot achieve the effect of uniform airflow and temperature in the refrigerated compartment
