Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerating vehicle for transporting food while cooling foodstuffs and other objects to be conveyed stored in a luggage compartment.

[0002]

2. Description of the Related Art Conventionally, when transporting fresh food such as fresh fish, a refrigerating car or a refrigerating car, which is a refrigerating car, is used to maintain freshness. These vehicles are equipped with a refrigerating or refrigerating unit including a compressor, a condenser, an evaporator, and the like, and are provided with a drive device for driving the compressor of the refrigerating or refrigerating unit.

This drive device is mainly a direct drive type drive device for taking out power from a running engine to drive a compressor 1 and the like, as shown in FIG. 7, because it is lightweight and inexpensive in small and medium-sized vehicles. Has been. And, when such a direct connection type freezing or refrigerating device is provided,
The condenser 2 having a heat exchange fan is installed under the floor of the vehicle as an extension of the compressor 1 and the like.

[0004]

However, in the case of the direct connection type, the compressor 1 cannot be driven when the running engine is stopped when the vehicle is stopped. Therefore, a separate compressor driving engine must be provided, but in that case, It increases vehicle weight, increases initial cost and running cost, and causes noise. Moreover, if the compressor driving engine is provided under the floor of the vehicle, the use of the underfloor space of the vehicle in the case of providing various facilities and devices is limited.

The object of the present invention is to eliminate the disadvantages of the prior art and to provide a second refrigerating or refrigerating vehicle in a refrigerating vehicle equipped with a direct-coupling type refrigerating or refrigerating device for taking out power from a running engine to drive a compressor or the like. Cooling operation can be performed even when the running engine is stopped when the vehicle is stopped using the refrigerator.
Moreover, since the drive energy can be obtained from a commercial power source via an outlet, unlike the case where a compressor drive engine is installed, the weight is not large, there is no noise, and the underfloor of the vehicle can be used for other purposes. It is to provide a refrigerated vehicle that can be effectively used.

[0006]

In order to achieve the above-mentioned object, the present invention firstly provides a refrigerating or refrigerating vehicle equipped with a direct coupling type refrigerating or refrigerating device for taking out power from a running engine to drive a compressor or the like. The refrigerating or refrigerating apparatus is a first refrigerating or refrigerating apparatus, and in addition to the first refrigerating or refrigerating apparatus, a second refrigerating or refrigerating apparatus for obtaining a compressor-powered motor power source from a commercial power source is provided in the cabin of the cab. Installed on the roof, secondly, the second refrigerating or refrigerating device should be flat so as not to greatly exceed the height of the luggage compartment on the cab of the cab, and be surrounded by the baffle plate. Third, second refrigeration or refrigeration system and first
Installed side by side with the condenser of the refrigerating or refrigerating machine of the above, and surrounding them with a common wind guide plate. Fourth, (a) aluminosilicate and (b) in the luggage compartment. ) It is a gist to dispose a plate coated with a deodorant paint containing an oxidizing agent and having a pigment volume concentration (including aluminosilicate and oxidizing agent) of 20% to 40% in the coating film. Is.

According to the first aspect of the present invention, when the vehicle is traveling, the first refrigerating or refrigerating device is used, and power is taken from the engine to drive a compressor or the like to perform a cooling operation. To cool the luggage compartment. Further, when the vehicle is stopped, the cooling of the luggage compartment can be continued by using the second freezing or refrigerating device. Furthermore, since the second freezing or refrigerating device can be installed without occupying the underfloor of the vehicle, the underfloor or the like can be effectively used for other purposes. In particular, in a refrigerated vehicle, there is a difference in height between the cab of the cab and the luggage compartment, which is a box-shaped vehicle body, and the box-shaped vehicle body is higher, but the second refrigerating or refrigerating device is mounted on the roof of the cab. It can be installed using the difference.

According to the second aspect of the present invention, in addition to the above-mentioned function, the second refrigerating or refrigerating device is flat so that the height of the luggage compartment is not greatly exceeded above the cabin of the cab. Moreover, by enclosing with the baffle plate, it is possible to reduce the air resistance received in the front portion of the luggage compartment of the box-shaped vehicle body which is higher than the cab of the cabin during traveling, and to save fuel consumption.

According to the third aspect of the present invention, the condenser of the first refrigerating or refrigerating apparatus is arranged side by side with the second refrigerating or refrigerating apparatus and installed on the roof of the cabin of the operator's cab. You can open the underfloor space of the vehicle in this space and use it effectively for other purposes.

According to the fourth aspect of the present invention, the malodor produced in the luggage compartment is eliminated by the deodorant paint applied to the board, and the deodorant paint has an excellent deodorant effect against various malodors. It has excellent deodorant speed and excellent durability. According to this deodorant paint, it is considered that physical adsorption proceeds at a very fast rate until equilibrium adsorption, followed by a chemical reaction. That is, by combining the aluminosilicate of the component (a) and the oxidizing agent of the component (b), the speed of adsorption of the malodor on the aluminosilicate having a large specific surface and the chemical reaction by the adsorbed malodorous oxidizing agent. And synergistically act to deodorize more effectively. Furthermore, by controlling the pigment volume concentration in the coating film within an appropriate range, the deodorant base is effectively deodorized without being hidden by the binder resin in the coating film, and the adsorption and chemical reaction The bad odor captured by the odor is no longer re-released as an odor, and deodorization, which is a drawback of deodorization due to physical adsorption, is suppressed, and the deodorizing effect continues.
